Putzbrunn, (May 21, 2026) – Firefighters typically wear the same protective clothing for all operational responses, whether they are carrying out technical rescue or structural firefighting assignments. Their protection is designed to meet the most extreme conditions such as a flashover in a structural fire.

But firefighters do not tackle structural fires on a daily basis. Most operational responses are for rescue operations, accidents or small fires. This means that they are often responding to incidents ‘over protected’ by gear that was designed for more extreme conditions, potentially raising the risk of heat stress.

Added to this, their needs not only differ, they can even be conflicting, compromising their operational effectiveness in one scenario for effective protection in another. Freedom of movement and high visibility are essential for technical rescue professionals. Wildland fire operations call for garments that are lightweight and heat-resistant. Firefighters tackling a building fire need maximum insulation and protection against exposure to heat and flame.

“The challenge is to reconcile conflicting needs to remove the compromise in operational effectiveness and mitigate the risks of overprotection. Freedom of movement, weather protection and thermal protection cannot be optimized in one garment. A garment that fulfils the requirements of all operational scenarios will always involve trade-offs,” says Christophe Didelot, the firefighting and technical rescue product specialist at GORE-TEX® Brand.

Two garment layers instead of a one-fits-all configuration

GORE-TEX® Brand is presenting an innovative new design concept for fire garments at INTERSCHUTZ 2026 that solves this paradox. Instead of combining multiple requirements in one garment, the concept presents two adaptable garment layers based on existing product technologies.

Each can be worn alone or in combination, depending on the mission:

• Layer 1 for technical rescue operations and other frequent call-outs is based on the GORE-TEX® CROSSTECH® PYRAD® Stretch Product Technology. It is lightweight and designed for freedom of movement and comfort.
• Layer 2 uses GORE-TEX® CROSSTECH® Product Technology and is a stand-alone solution for wildland fire call-outs and outside operations. It fulfils the performance requirements of EN 469 level 1 and EN ISO 15384.
• The two layers can be worn in combination so that together they provide EN 469 level 2 protection for structural firefighting.

Instead of incorporating the required protective features into one and the same garment, they are now integrated into two adaptable clothing layers. This means that the lighter Layer 1 is worn alone for technical rescue operations and Layer 2 for wildland fire call-outs. For structural firefighting operations the two layers are worn together.

So, two garment layers now meet the needs of three operational scenarios. This also reduces the number of garments required, simplifying procurement and maintenance and saving time, effort and expense.

The decisive factor is not maximum performance at all times, but the appropriate garment for the specific purpose.

A proven principle from other sectors

GORE-TEX® Brand has been developing modular clothing systems and the underlying product technologies for multiple professional scenarios for many years. These solutions are focused around a layering principle which interprets clothing as a system of fine-tuned, carefully coordinated layers rather than a standard uniform.

Examples of these are the Nordic Combat Uniform (NCU) of the Nordic Defence Cooperation and the Flexible Layering Systems of the German police. These concepts are based on a clearly defined layering construction. The individual garment layers are carefully chosen depending on the climate, physical demands and intervention type. Each individual layer may not meet all the requirements, and not all components will be worn together.

These layering systems are developed and tested by Gore in realistic situations. Durability testing and wet laboratories, a rain tower, as well as climate and environmental chambers are used for this purpose. These are complemented by field tests conducted by end-users.

The underlying motive is to analyze how heat, moisture, physical demands and protection influence each other during operations. The result is a garment system whose performance is achieved at the system level – through the coordinated interaction of the individual layers and not through isolated individual components.

Putzbrunn, (4th March 2026) – The heat shimmers, sweat burns in the eyes, every move must be right: In such moments, climate comfort determines how long concentration and performance are maintained. What was previously often fraught with compromises – flame retardancy on the one hand, lightness, and breathability on the other – is combined in the new PYRAD® product technology by GORE-TEX LABS®, thus complementing the GORE-TEX® brand's product portfolio of flame-retardant, membrane-free laminates for military combat suits.

Many conventional flame-retardant textiles usually come with a dilemma: Although they provide reliable protection against heat and flames, they are often heavy, stiff, and hardly breathable. For soldiers, this means an additional burden in the field - and in extreme cases heat stress, limited freedom of movement and faster fatigue. The new generation of laminates with PYRAD® product technology by GORE-TEX LABS® solves this issue: It offers protection in the event of sudden flames and ensures a more comfortable and cooler feel with its extremely low weight, high air permeability and stretch content - even when using heavy equipment.

Paving the way for combat suits that can be used worldwide

"With the new technology, the GORE-TEX® brand is expanding its product portfolio of flame-retardant, membrane-free laminates for ground troops, air force and navy combat suits – and now covers all climate zones and mission profiles," explains Andreas Marmsoler, Strategic Marketing for the Defence sector at the GORE-TEX® brand: "In addition to the robust generation for temperate to cool climates, a much lighter, more elastic solution is now available. They impress with excellent moisture regulation, quick re-drying, and high wearing comfort in warm to hot climates, especially during high-intensity use.

Depending on the application scenario, the new generation can be combined with other, more robust laminates in a combat suit. For example, lightweight materials can be used in less stressed areas such as the chest or legs, and more resistant laminates in high-wear zones such as shoulders, elbows, or knees.

High-performance material for practice

The compact structure of the material is made possible by the PYRAD® product technology, which is based on a physical effect: it consists of countless small reactive graphite particles that are evenly incorporated into the fabric. When in contact with flames or a flash flame, they form a stable, self-extinguishing carbonisation layer that reliably protects the wearer.

Maximum safety with a high level of comfort – proven in the field

Practical field tests with special forces and naval personnel in the Middle East, the Mediterranean and the Pacific prove the performance of the new technology: The combat suits durably withstood the wear and tear from plate carriers, thorns, brambles, and abrasive surfaces without losing function or producing disturbing noises when moving. Especially in hot climates, the comfort advantage over conventional materials was clearly evident at medium to high activity – with many users referring to lower fatigue and thus higher operational readiness.

“Studies show that firefighters worldwide prefer lighter boots, which is exactly where our EXTRAGUARD upper technology comes in,” explains Johannes Krieg, product specialist at GORE-TEX Professional Fabrics. “In cooperation with HAIX we have developed a new generation of athletic fire boots that are taking comfort and safety on the job to the next level.”

Innovation on three layers

EXTRAGUARD upper technology is made of three functional layers: a highly abrasion-resistant and flame retardant outer protective layer, an insulating mid-layer offering protection against mechanical impact and an innovative low water absorption construction. The entire construction is seam-sealed with the tried and tested GORE-SEAM® Tape and combined with a GORE-TEX CROSSTECH® inner lining. The outcome: a boot that is durably waterproof, breathable and chemically resistant, protects against pathogens and is still very comfortable. FIRE EAGLE 2.0 EXG boots reliably protect wearers against heat and flame and comply with DIN EN15090:2012 as well as the requirements of F2A.

Wearer trial: Munich’s fire services are convinced

A wearer trial conducted in cooperation with Munich’s fire services showed the boots deliver what they promise. 22 firefighters tested the new fire boots for roughly 12 months during various fire service activities including technical rescue operations, fire incidents, severe weather events, and emergency responses. 73% of the participants said the boots were “lightweight”, while 9% even thought they were “very lightweight”. The test boots also made a good impression when it came to re-dry: 73% said it was “good”, while 27% said it was “very good”. 91% of the firefighters said they would also continue wearing the boots during regular duties.

Revolutionary technology for real emergencies

The EXTRAGUARD upper is 40% lighter than conventional materials and hardly absorbs any moisture from the outside. This ensures that the HAIX FIRE EAGLE 2.0 EXG offers lasting lightness when worn for hours in wet conditions, dries faster and is durably waterproof even in extended periods of heavy water exposure. External moisture can hardly penetrate beyond the low water absorption construction layer, ensuring reduced conduction heat loss and preventing the feet from being robbed of warmth. Feet stay dry and warm, even in wet and cold conditions.

The HAIX FIRE EAGLE 2.0 EXG needs no breaking in and fits right from the start. There is hardly any need for additional reinforcements in the boot construction. This improves weight, breathability and wearer comfort. Its robustness minimises signs of wear and it is easy to clean: simply rinse the boots under the tap or hose them down. Specific care products are not necessary.

A long product life translates into sustainability

The EXTRAGUARD upper is extremely robust, thus extending the product life of the HAIX FIRE EAGLE 2.0 EXG firefighting boot, while reducing its ecological footprint. Using few resources and minimising CO2 emissions, the material also sets new standards in terms of its production.

HAIX FIRE EAGLE 2.0 EXG fire boots are immediately available for purchase from the HAIX website and from specialty retailers in UK sizes 2 to 11.5 (EU 35 to 47), as well as in extra large sizes 12 to 15.5 (EU 48 to 51).

The specialist for technical functional textiles will be presenting the laminates for this system at Enforce Tac 2024 in Nuremberg (February 26 - 28, 2024) at booth 7A 537.

The basic idea behind the system comes from the military: layers of clothing that can be flexibly and modularly adapted to the operating conditions. After all, no two days are the same in the police force: Police officers have to withstand heat, cold, wind, moisture, chemicals, and flames on duty. Every deployment has high demands on freedom of movement, especially when wearing additional protective equipment.

Three layers of clothing for tailored protection and comfort

The three layers of the flexible system can be worn individually or flexibly combined with each other. GORE-TEX Professional has developed customised laminates for each layer:

Layer 1: Daily Duty Uniform (DDU)

This lightweight base layer offers protection and comfort for everyday use. It is highly abrasion-resistant and therefore durable, breathable and quick-drying. The uniform is equipped with the innovative PYRAD® technology for flame protection.

Layer 2: Insulated Riot Suit

The second layer can be worn over the Daily Duty Uniform (DDU) in cold or wet weather. With the comfort and appearance of softshell clothing, it can be equipped with either GORE-TEX technology for moisture protection or WINDSTOPPER® technology by GORE-TEX Labs for absolute protection from the wind. PYRAD® technology is always included.

Layer 3: Hardshell Riot Suit

Like the Insulated Riot Suit, this additional layer offers durable protection against moisture as well as common chemicals, heat, and flames. The Hardshell Riot Suit can be combined with any of the other clothing layers. It is optionally available with lightweight PYRAD® technology or as a 3-layer laminate with aramid outer fabric.

PYRAD® technology for reliable protection against heat and flames

PYRAD® technology is based on a physical effect: countless small and reactive graphite particles are evenly and permanently incorporated into the fabric. If the particles are activated by sudden heat or flames, they suddenly expand by more than ten times their original size, forming a stable, gapless carbon layer. This greatly reduces the flow of heat through the fabric and stops the spread of flames. As a result, no holes form, there is no afterburning and no dripping.

GORE-TEX FR Stretch for maximum freedom of movement

Stand, run, defend yourself: A high degree of freedom of movement is essential in the field, especially when additional protective equipment such as impact protection has to be worn. To improve the mobility and fit of the clothing, the laminates can therefore be combined with the new, flame-retardant, and waterproof GORE-TEX FR Stretch laminates. This allows unprecedented freedom of movement and fewer restrictions - regardless of whether the body protection is worn under or over the clothing. Clothing worn close to the body also increases its breathability.

Tested, approved, and procured by most Swiss cantons

Following extensive tests, most Swiss cantons will be using the system's laminates in future: "The Flexible Layering System fits perfectly into our new overall range of flame-retardant clothing for the non-peaceful law enforcement service. In addition to the high level of functionality in terms of weather and flame protection, we are impressed by the light weight and high level of comfort," said Daniel Bernasconi, Project Manager for the cross-corps renewal of work uniforms (KEP).

The Riot Collection is tailored to provide protection in each layer of clothing, from first layer to outer layer, so that they work together to meet varying weather, activities and operational challenges. The garments incorporate the inherent flame-retardance and heat-resistance that comes with PYRAD® technology.

A new PYRAD® Duty Uniform by GORE-TEX LABS combines lightweight, highly breathable comfort with flame retardance. The riot suit has very low water pick up, with fast redry for everyday comfort.  

 The GORE-TEX PYRAD® Riot Suit is lightweight, abrasion resistant, waterproof, breathable and comfortable while still protecting the wearer from liquids, common chemicals, heat and flash fire.  

Insulated versions offered from different laminates for the Riot Suit are ideal for officers for use in colder months. They can be designed using body mapping that ensures the insulation is only added where needed, reducing unnecessary bulk and improving freedom of movement. 

The unique flame-retardant GORE-TEX Stretch technology offers additional freedom of movement, not only, but especially in combination with protective vests. 

The GORE-TEX Professional product collection with flame-retardant protection solutions makes the job easier as it is lighter, softer and more comfortable than conventional clothing. With high levels of comfort and protection, officers will not be hampered by becoming too wet, too cold or too warm and can better concentrate in the task in hand.  

Katja Christof, Product Specialist at GORE-TEX Professional, said: “We are continuously innovating to expand and enhance the choice of high-performance protective clothing solutions available to police forces.  The GORE-TEX Professional Riot Product Collection delivers critical protection for officers and offer much greater flexibility to forces so that they can procure garments that are designed to meet their own specific operational needs. This will result in improved comfort and protection for officers, helping them to better perform their day-to-day duties and deal more effectively with the challenges of modern-day policing.”  

All the materials in the PYRAD® range are highly durable and designed to withstand the rigours of operational deployment in challenging environments with high abrasion resistance. They are available in a wide range of colours to suit the different corporate identity needs of police forces.

Paul Jennewein, product specialist at GORE-TEX Professional for flame-retardant military clothing, explains: "The PYRAD® product technology takes soldiers' equipment to a new level. It offers critical protection against sudden flames whilst also providing a high level of comfort and freedom of movement, thanks to the lightweight fabric." 

Durable heat and flame barrier with and without membrane  

PYRAD® product technology is used for combat suits either without a membrane or with a GORE-TEX® membrane, depending on the situation and weather conditions. PYRAD® technology by GORE-TEX LABS provides effective protection against sudden heat and open flames - and combined with an integrated GORE-TEX membrane, also protects against common chemicals, common fuels such as gasoline and diesel, most diluted acids and alkalis. 

Combat suits with PYRAD® textile technology without a membrane are ideal for operations in warm areas. Soldiers then only need one combat suit with integrated flame protection. They are also suitable as a battle dress uniform (BDU), especially for physically demanding activities: the uniform contains only one textile layer and can therefore also be worn comfortably under a combat suit. 

PYRAD® technology from GORE-TEX LABS in a fitness-for-use test 

Gore had the "fitness for use" and operational suitability of the PYRAD® product technology simulated in a test emergency scenario. Both types of combat suits underwent tests which were conducted in a strictly controlled environment and with safety as a top priority:

Accident during refueling of military vehicles or aircraft 
Under combat conditions when refueling military vehicles and aircraft, fuel can get onto soldiers' clothing and ignite through contact with an ignition source such as open fire, sparks or extremely hot surfaces. In the test, a GORE-TEX PYRAD® Defence FR rain suit was sprayed with a diesel-petrol mixture and ignited by a small gas deflagration. 

Heat and flames from improvised explosive devices 
Improvised explosive devices (IEDs) are a threat to soldiers on missions around the world. In the test a PYRAD® combat garment by GORE-TEX LABS was confronted with two large gas explosions, a continuously burning gas flame as a heat source and lycopodium used as an additional fire effect in the background. 

"The tests under real conditions have impressively shown that the PYRAD® technology delivers what it promises: our technology protects emergency personnel who stand up for our society - under the toughest conditions," Paul Jennewein, product specialist at GORE-TEX Professional for military clothing, evaluates the fitness-for-use tests.

Working closely with manufacturers and users of protective workwear, GORE-TEX Professional (Gore) has deep insights into the needs of wearers. Now, the functional apparel specialist has combined its expertise in workwear design trends with innovative PYRAD® technology. It protects industrial workers and people in the energy supply industry from the thermal hazards of electrical arcing, flames, and heat

High-tech safety materials ensure that electrical engineers and industrial workers can rely on their personal protective equipment (PPE). But time and again PPE is perceived as complicated, often heavy, and uncomfortable. This can lead to it not being worn, or not being worn correctly and as a result the protective function is also impaired.

Consulting starts with design and cut

With its design ideas, GORE-TEX Professional inspires the industry and supports PPE manufacturers in implementing state-of-the-art protective clothing. Because design and cut are becoming increasingly important for wearer acceptance.

Up-to-date design, ergonomic cut, well thought-out details, and lightweight high-tech materials that are pleasant to the touch ensure that PYRAD® jackets and trousers garments provide optimum protection and are extremely comfortable to wear. The more comfortable people feel in their PPE, the more focused their performance is at work. Only when worn correctly does it protect the user and the environment.

What wearers want - modern, lightweight PPE

From wearer trials, testing and feedback discussions, it is clear that wearer comfort and modern design is a key demand for end users and procurers. Workers want to wear modern and comfortable safety clothing in a professional environment, in the same way they wear functional and contemporary garments for sports and leisure.

What already exists in the workwear sector is now also possible for highly functional PPE. Gore has developed ideas that combine material science, technological knowledge, and design for high-performance PYRAD® protective workwear, illustrating what modern PPE can look like today.

Protective clothing with GORE-TEX PYRAD® product technology is durably waterproof and windproof, at the same time breathable and up to 45% lighter than conventional PPE within the same protection class. The garment can be combined as needed: offered with a 2-layer laminate in the form of lightweight, quick-drying rainwear for indoors and outdoors, or with a 3-layer laminate for extreme weather situations. Comfort Mapping -  (this considers the distribution of heat and moisture production in various parts of the body and uses contrasting textile materials for different parts of the garment) - prevents overheating on warm days or during heavy work. Assorted colour combinations, such as high visibility with solid colours, are also available. The arc rated protective clothing also integrates design elements from outdoor sports such as body-hugging cuts, ergonomically shaped sleeves, smart pocket solutions and detachable hoods.

Interview with GORE-TEX Professional designer Reza Jamshidi-Azad

How did you go about identifying these trends for PYRAD® protective workwear?

We talked to users of workwear and protective clothing about comfort, function, materials, and product details - and had them explain to us what their job looks like and what their needs are. At the same time, we keep a close eye on what is happening in fashion and sports.

Which professional groups are addressed by the different design trends?

Basically, all occupational groups that need PPE can avail themselves of all trends with the appropriate elements.

Why is it increasingly important that PPE not only protects, but is also stylish?

People love stories. And storytelling is also increasingly happening through clothing. It is a way of expressing pride in belonging to a particular company. What brands are in fashion, the factors of fit and design are in workwear. Ultimately, this is exactly what affects how PPE works: If it is comfortable and pleasing, the PPE will be worn gladly, continuously, and correctly - and can fully fulfill its protective function.

“The high breathability of PYRAD® switch suits is important for thermal regulation because end users are often working in arc flash risk areas indoors and in confined spaces. This means wearers no longer have to compromise between breathable comfort and reliable safety protection”, says Miguel Calixto, Arc/FR  Workwear product specialist at GORE-TEX Professional.

Switching suits, made up of bib trousers, jacket and full (bee-keeper style) hood are worn together when there is any risk of an arc flash incidents: IEC 61482-1-2 Class 2 and IEC 61482-1-1 APTV ≥40cal/cm².

Until now, typical Class 2/ 40 cal garments that are required to protect workers against the thermal hazards of electrical arc flashes with high incident energy risk exposures have been made from multi-ply fabric systems resulting in them being bulky, restricting movement, heavy and uncomfortable to wear. 

Science & technology behind new PYRAD® switch suits by GORE-TEX LABS

Gore’s research and development team have combined 4 functional components into a durable single-ply material that interact with each other. The fabric weighs in ≤330 g/m² which means it is up to 20% lighter than other products currently available in the market. It consists of a nylon outer shell, PYRAD® fabric technology by GORE-TEX LABS, an advanced membrane, and a flame-resistant backer.

Nylon outer shell: this fabric can be dyed into a number of different colour fast shades, has tensile strength and offers excellent abrasion and wear resistance.

PYRAD® Fabric Technology: this adds durable heat, flame, and arc resistant protective properties to the nylon outer shell. The flame-resistant protection from PYRAD® fabric technology is not a chemical treatment or coating. It is inherent to the fabric and as a result it is durable for the life of the product and doesn’t wear off over time. It is made up of countless dots which rapidly react to heat during an arc flash exposure, even before the outer shell has chance to burn.  The reaction of the dots causes them to expand by more than 10x larger than their original size and form a stable insulating protective shell of carbonaceous char. This blocks the transfer of heat to skin and stops flame propagation.

Membrane: an extremely light weight and wafer-thin membrane which provides highly breathable and thermally stable properties for strength, flexibility, and mechanical integrity.

Flame resistant backer: this component further reduces the transfer of heat to the wearer. Miniscule air pockets caught between the Gore membrane and this backer expand instantly on contact with heat to form an additional layer of protection.

Key Benefits and Features

When compared to multi-layer switching suits, the benefits of Arc Rated PYRAD® switch suits by GORE-TEX LABS made from the single-ply fabric technology include:

• Reduced bulk and high freedom of movement meaning less muscle fatigue,
• A unique combination of the lightest weight fabric with Class 2/ 40 cal arc protection,
• Breathable garments so wearer feel more thermally comfortable.

Extensive tests have proven that during arc flash exposure the laminate provides best-in-class mechanical integrity:

• Blocks convective and radiant heat,
• Stops flame propagation,
• Forms a carbonaceous char meaning, the laminate keeps its physical integrity and will not flake or disintegrate, and no holes are formed.

EU Multi norm compliance of the Arc Rated PYRAD® switch suits by GORE-TEX LABS includes:

• Protective clothing against the thermal hazards of an electric arc, IEC 61482-1-2 Box test Class 2 (7 kA) and IEC 61482-1-1, Open-air arc test ATPV ≥ 40 cal/cm²

The speed and strength of wind has a great influence on how cool a worker feels during outdoor work or operations. Personal protective clothing with PYRAD® WINDSTOPPER® technology by GORE-TEX LABS technology offers the lightest weight Class 2 arc protection for cold and windy conditions. It is totally windproof and thus protects against unpleasant cooling caused by wind chill. In addition, it provides maximum breathability for improved wearing comfort in windy weather. The laminate's lightweight construction facilitates freedom of movement for Personal Protective Equipment (PPE) wearers, ideal for physically demanding jobs that require dexterity and flexibility. "PYRAD® WINDSTOPPER® technology by GORE-TEX LABS provides the most consistently warm Class 2 arc protection for cold, windy and moderately rainy weather conditions - without compromising weight or breathability", summarises Miguel Calixto, FR/ARC Multinorm Workwear Product Specialist at GORE-TEX Professional.

The PYRAD® WINDSTOPPER® laminate technology by GORE-TEX LABS consists of 3 layers - a water-repellent face fabric for protection against moderate rain, a special membrane that completely blocks wind while incorporating protective PYRAD® technology, and a soft backer for balanced thermal comfort protection. PYRAD® WINDSTOPPER® technology by GORE-TEX LABS is versatile and suitable for a variety of garment types including jackets, trousers, and coveralls.

PYRAD® technology: real-time protection through stable char layer

The PYRAD® product technology is based on a physical effect: it consists of countless small reactive dots homogeneously distributed over the fabric. When the fabric is strongly heated by a sudden flame or arc flash exposure, the dots react and expand by more than 10 times their original size to form a stable, gapless carbon layer that effectively inhibits heat flowing through the fabric. The result: no holes in the textile, no burning of clothing worn underneath, no burns on the skin even when exposed to the strongest heat.

Proven protection and comfort

PYRAD® WINDSTOPPER® technology by GORE-TEX LABS has been tested to IEC 61482-1-2 (Arc Rating Class 2) and IEC 61482-1-1 with an ELIM (Incident Energy Limit) value of ≥40 cal/cm² and an ATPV value (Arc Thermal Performance Value) of ≥45 cal/cm².  This ensures reliable and constant arc fault protection.  In addition, the innovative technology combination also meets EN ISO 11612 standards (ISO 11612 Class A1, A2, B1, C1, D1, E1, F1) for flame retardancy and EN 13034 for protection against liquid chemicals. It is EN ISO 11611 compliant and provides protection against sparks and metal particles during welding. The laminate of PYRAD® WINDSTOPPER® Technology by GORE-TEX LABS also has antistatic properties according to EN ISO 1149 3/5 and is available in high-visibility colors (Hi Vis Yellow and Orange) that comply with EN ISO 20471. The excellent breathability of the technology is certified by EN ISO 11092.

Sustainable manufacturing and material selection

The PYRAD® WINDSTOPPER® technology by GORE-TEX LABS is manufactured using PFC-free DWR (durable water repellency). Thanks to the use of 100% recycled polyester in the outer fabric plus a liner made from a carefully selected blend of fibres, the technology has a low environmental footprint (as measured by the MSI Higgs Index). It also complies with OEKO-TEX® Standard 100 and California's Prop 65.

The PYRAD® Technology by GORE-TEX LABS laminate combines three components in a single-ply fabric. Each component  is an integral part of the fabric structure: the 100% recycled polyester face fabric, a special ePTFE membrane which, for the first time, has the protective PYRAD® technology integrated onto both sides of this membrane, and a backer which is partly made from recycled content. This new application of PYRAD® technology onto both sides of the special ePTFE membrane has enabled Gore to use new sustainable textile components for the face and backer fabric to reduce the overall weight (280g/m²) and improve the suppleness of the fabric. “This unique construction of PYRAD® Technology by GORE-TEX LABS allows for an extremely lightweight and comfortable, yet durable and highly functional garment design with the highest level of arc flash protection" explains Miguel Calixto, FR/ARC Multinorm Workwear Product Specialist at GORE-TEX Professional.  With a water vapor transmission resistance (Ret value) of less than 13m² Pa/W, the new generation of technology features high breathability, resulting in less body heat accumulation - and providing a comfortable thermal wearing experience, especially during physical work.

"The new laminate's Class 2 arc protection rating gives engineers and workers in the industrial and electric utility sectors assurance that they are not only optimally protected from possible arc faults but are also completely comfortable. With this knowledge, they can fully concentrate on their important tasks," says Miguel Calixto. PYRAD® technology by GORE-TEX LABS can be used to manufacture lightweight arc flash PPE for everyday use that is just as comfortable to wear indoors as it is outdoors on warm dry days. 

Low environmental footprint due to sustainable material selection and production

The technology also scores in terms of sustainability: PYRAD® technology by GORE-TEX LABS is manufactured using non-fluorinated treatments. The 100% recycled polyester outer face fabric ensures its low ecological footprint (measured by the MSI Higgs Index), and the innovative technology also complies with the OEKO-TEX® Standard 100. In addition, the backer is also constructed using partly recycled content.

PYRAD® technology: real-time protection through stable char layer

The PYRAD® product technology is based on a physical effect: it consists of countless small reactive dots homogeneously distributed over the membrane. When the dots are strongly heated by a sudden flame or arc disturbance, they react and expand by more than 10 times their original size to form a stable, gapless carbon layer that effectively inhibits heat flow. The result: no burns on the skin, no burning of clothing worn underneath, no holes in the textile even when exposed to the strongest heat.

Maximum safety through comprehensive protection

PYRAD® technology by GORE-TEX LABS has undergone rigorous testing in the GORE-TEX Professionals laboratories and meets the requirements of arc protection class 2 according to the European standard (IEC 61482-1-2 (Box test class 2), IEC 61482-1-1 (Arc rating ATPV ≥ 35 cal/cm²; ELIM ≥ 30 cal/cm²). In addition to arc protection, the new technology offers heat and flame protection (ISO 11612 class A1, A2, B1, C1, D1, E1, F1), antistatic properties (EN 1149-3/-5), protection against chemicals (EN 13034 type 6) and welding protection (EN ISO 116111 class 1 A1+A2 compliant).

Following the trade launch of PYRAD® Technology by GORE-TEX LABS at A+A 2023, garments utilising this new technology should be available from Gore’s licenced manufacturing brand partners in the course of 2024.

Gore fabrics products provide comfort and protection in challenging environments and in everyday life, enabling wearers to safely and confidently achieve and experience more. From hiking in downpours to defense operations and fighting fires, Gore’s deep understanding of consumer and industry needs drives development of products with meaningful performance advantages. gore-tex.com and goretexprofessional.com

New arc rated GORE-TEX PYRAD® stretch technology is the result of intensive research and development. It combines GORE-TEX Professional’s (Gore) proprietary technologies with different engineering techniques: the resulting arc rated Class 2 fabric technology has a unique stretch attribute which provides electrical workers with an extremely comfortable, easy to wear and lightweight solution to arc rated foul weather protection.

This multi-norm compliance fabric technology stands far above other existing arc rated hardshell rainwear solutions, as typically norm compliant PPE for electrical workers is heavy and bulky, restricts freedom of movement and absorbs water. This new fabric technology is remarkably different because it has 50% more stretch than other existing products available. It is waterproof, lightweight, flexible, and noticeably soft and comfortable to wear. Unlike other fabrics which serve this industry to protect workers against the risk of an accidental arc, it is also remarkably quieter when worn.

Arc Rated GORE-TEX PYRAD® Stretch Jackets and Trousers deliver flexible comfort and improved overall fit and are 45% lighter than other Class 2 arc protection rainwear. Workers can easily bend, kneel, climb, and stretch without any restriction of movement thanks to the innovative new GORE-TEX PYRAD® stretch technology.

Miguel Calixto, product specialist at GORE-TEX Professional comments: “The new arc rated GORE-TEX PYRAD® Stretch fabric technology has been developed with real-work situations and end user needs in mind and I believe we are setting new standards in arc rated multi-norm protective apparel, combined with lightweight stretch wearer comfort.”

The fabric consists of 2-layers in combination with a flame-resistant liner, an outer shell fabric and an advanced elastic ePTFE membrane, coupled with the protective GORE-TEX PYRAD® fabric technology. Its increased stretch is the result of the elasticity of the laminate, which is determined and conforms to EN ISO 20932-1:2020 + A1:2021. At a load of 30N the new GORE-TEX PYRAD® stretch laminate achieves an elongation of more than 12% in warp direction. It recovers over 85% of its original shape after being stretched. Typically conventional, non-elastic fabrics stretch less than 5% and recovery back to its former shape is poor. The elastic properties are durable and will not deteriorate in use or when laundered.

Multiple Wearer Benefits

New GORE-TEX PYRAD® Stretch Jackets and Trousers are ergonomically designed to support natural freedom of movement without constricting the wearer. Arc Rated GORE-TEX PYRAD® garments are durably waterproof and resistant to common hazardous liquids. They totally block out the wind, even in the stormiest conditions, which eliminates any wind chill factor and helps to maintain a comfortable wearing temperature. Additional wearer comfort is achieved because jackets and trousers engineered with GORE-TEX PYRAD® stretch technology delivers a 25% increase in breathability. This helps to prevent a buildup of moisture on the inside of the garments.

How does the GORE-TEX PYRAD® fabric technology work?

During an arc flash exposure, GORE-TEX PYRAD® fabric technology (countless reactive dots) rapidly reacts to the heat even before the outer shell starts to burn. The reaction of the dots causes them to expand by a magnitude of more than 10x higher than its original size and form a stable insulating protective shell of carbonaceous char with the face fabric (without melting or dripping) stopping flame propagation, blocking convective and radiant heat from the arc flash exposure, and reducing the heat transfer to wearers skin. In addition, the physical integrity of the laminate is maintained after heat and flame exposure, which means no break or hole formation.

Norm Compliance of the new GORE-TEX PYRAD® stretch technology includes:

• Protective clothing against the thermal hazards of an electric arc, IEC 61482-1-2:2014 class 2 (7 kA), IEC 61482-1-1:2019, arc rating (Arc rating ELIM ≤ 40 cal/cm²; ATPV ≤ 46 cal/cm²) tested with 120 g/m² aramid/viscose (50:50) lining.
• Clothing to protect against heat and flame, EN ISO 11612 A1, A2, B1, C1, D2, E3, F1 clauses 7.2 – 7.6 (code letters B, C, D, E, F) tested with 120 g/m² aramid/viscose (50:50) lining.
• Protective clothing for use in welding and allied processes, EN ISO 11611 class 1 A1+A2 clauses 6.8 – 6.10 tested with 120 g/m² aramid/viscose (50:50) lining.

Paul Jennewein is a product specialist for flame-retardant (FR) mission combat clothing at GORE-TEX Professional. At the test site, he wants to test two scenarios that users in the military are exposed to: one is an accident during refueling of a vehicle or aircraft, and the second scenario involves an infantryman who gets caught in the explosion of an improvised explosive device (IED). The tests were performed by a professional stunt team in a controlled environment, secured by fire fighters.

Accident during refueling of military vehicles or aircraft

When refueling vehicles and aircraft under combat conditions at all times of the day and night, fuel frequently spills onto the clothing of the refuelers. Clothing wetted with flammable fuel can subsequently be ignited by contact with an ignition source such as sparks, extremely hot surfaces or the like. A Defense FR rain suit with GORE-TEX PYRAD® technology was tested. Jan Singh simulated this tank accident by spraying the right side of the suit with diesel and gasoline and then igniting it close to the ground by means of a small gas deflagration.

Heat and flames from improvised explosive device

Improvised Explosive Devices (IEDs) unfortunately continue to be a threat for soldiers on missions globally. In this scenario, the effects of the heat and flames caused by an IED on mission combat clothing are examined. Flame-retardant combat uniform made of PYRAD® fabric technology By GORE-TEX LABS, as worn by defense personnel in many European countries, is used. Jan Singh simulated this scene using two large initial gas explosions and a continuously burning gas flame as an additional heat source. Lycopodium was used as an additional fire effect in the background.

The greatest environmental impact in a lifecycle of personal protective equipment occurs during production and distribution. Extending the longevity, or useful life, of a product is therefore the single most influential factor to improve its environmental impact. This is especially true if a product can be repaired and re-used again. Following this spirit, Wenaas, an international supplier of workwear solutions from Norway, together with GORE-TEX Professional, developed a smart repair kit for arc rated GORE-TEX PYRAD® personal protective equipment (PPE) to help their customers prolong the garments’ product life.

Electrical workers often need to move through difficult, thorny terrain to locate a fault on the power network and climb high poles. During these activities their PPE can get stuck behind something sharp or spines, which, despite the robustness of the material, could result in a puncture or small tear of the outer fabric. While the garment overall would still be fit for use, a tiny puncture could result in a potentially dangerous situation for the wearer in case of an electric arc. By applying the patch, propagation of the tear is avoided, and garment lifetime extended.

“Norwegian electrical utility workers came to us with a problem: some of their employees had small punctures in their Wenaas GORE-TEX PYRAD® garment from walking through dense forest before reaching their service location”, illustrates Kristin Lien, product developer at Wenaas. “Together with Gore we concluded that it makes financially and environmentally no sense to replace the entire garment. GORE-TEX PYRAD® garments are top of line. Our collective goal is to let customers keep their garments as long as possible before having to replace them. Therefore, we developed the repair kit – a win-win solution: cost-effective as well as a very sustainable solution.”

Repair Kit for the garment

The repair kit consists of four GORE-TEX PYRAD® fabric patches: two round patches (diameter 7,6 cm) and two square patches (10 x 5 cm). These allow for the repair of small and medium-sized punctures or tears of the fabric – for larger damages two or more patches can be combined. The kit comes in two color versions: fluorescent yellow and navy blue. No special skills are involved to repair the garment: the patches have glue on the backside – a short instruction video shows that all that’s needed is a hairdryer and / or an iron to permanently attach the patch. After repair the risk of harmful incidents is avoided by using a protection patch made of GORE-TEX PYRAD® arc-protective materials and can be washed as usual. And in the rare case the fabric is damaged in the exact same place again, a new patch can even be applied over the previous patch. “The feedback from our customers is very positive”, concludes Lien, “the repair kit absolutely solved their problem.”

Jonas Andersson, sales Associate at GORE-TEX Professional says: “Our sustainability approach is about providing exceptional long-lasting products while at the same time reducing the environmental footprint. The idea of the repair patch is to avoid further tear propagation which could result in losing the required protection. And through these patches, users can contribute to our effort and do something meaningful.”

Northern Powergrid manages and maintains the electricity distribution network that powers everyday life for more than 8 million people across 3.9 million homes and businesses in the North East, Yorkshire and northern Lincolnshire. Its network of 63,000 substations and 60,000 miles of overhead power lines and underground cables safely delivers the electricity bought  from energy suppliers. As a 24/7, 365 business, it’s there for customers through a team of some 2,700 people including around 1,300 frontline utility workers. In an evolving energy industry, Northern Powergrid and its people have a key role in creating and managing future energy systems that increasingly interact with customers and smart and low carbon technologies.

Electrical Workers Needs

Utility and electrical engineering offer challenges to its workers, especially those who have to work daily in changeable weather conditions but with the potential risks of  the thermal hazards of electric arc flash.

Colleagues had remarked that the traditional wet weather PPE provided was bulky and heavy,  that it was often too warm to wear during strenuous work and that it took a long time to re-dry at the end of a shift. Arc rated PPE needs to offer the highest levels of protection for utility workers against the potential daily risks of thermal hazards from an electric arc, without weighing down the end user with garment bulk. When working with live electrical systems there is always a remote risk of a worker being exposed to an incident involving a high temperature arc flash. Such incidents are extremely rare but nevertheless, companies need to protect their engineers by procuring Class 2 arc rated protective workwear with flame retardant properties.  Garments which are Class 2 arc rated refer to the protection level of European Norm    IEC 61482-1-2 (Box test), which stands for: protective clothing against the thermal hazard of an electric arc. 

For wearer comfort, garments need to be light to wear – wet or dry – so they are able to be worn for long shifts, in changing weather conditions. Protective garments also need to be robust and durable to not only last, which makes them more cost effective but also help the environment because they have a longer wear cycle and need replacing less often. For engineers working at height, up on poles or platforms, PPE should enable free movement, be flexible and offer high visibility for safety.

In addition, Northern Powergrid workers may face a difficult journey before they start work to reach their assigned repair site. Sometimes, they are required to move through difficult terrain to locate a fault on the power network so clothing needs to be robust enough to protect the workers from more general hazards.

For these roles, the correct balance of protection, ruggedness, comfort and ergonomics is an essential prerequisite for the workers’ PPE.

Northern Powergrid’s PPE Developments

Sean Johnson, a Safety Engineer at Northern Powergrid for 39 years, responsibilities include legal standards, policy, accident investigation, risk assessments and operational controls.

Back in 2009, Sean was part of a project team at Northern Powergrid which analysed the protective characteristics of arc flash safety clothing through a study of the potential risks for operatives working within the network. This study helped determine what levels of protection were needed for the different roles and risks a frontline utility worker could face as part of their job.

Using this information, Northern Powergrid commissioned a number of key industry players to develop a specification that would answer protection requirements. The working group found solutions that would provide comfort, protection and the correct corporate palate, which at that time was black and red. Following wearer trials and agreeing the specification, a competitive tender was won by J & K Ross, UK based specialists in PPE, Health & Safety Clothing distribution. In 2013 Northern Powergrid clothing sets for the 1,300 strong workforce were produced and distributed in one logistical hit and within one month all colleagues had all the protective garments they required to work safety and with complete protection. The clothing sets contained a previous generation of GORE-TEX Heat and Flame wet weather garments arc rated Class 2 (Box test). One layer of clothing provided in excess of 8 cal/cm² of protection, while two layers would provide in excess of 30 cal/cm² of protection based on both the Arc Thermal Performance Value (APTV) and E_LIM Value.  

Recent Developments at Northern Powergrid

In 2020, Northern Powergrid set about developing new products with Gore, J & K Ross and Gore’s licenced manufacturing partner MSA Bell Apparel. Together, they started exploring how the new arc rated GORE-TEX PYRAD® technology might be adopted by the Northern Powergrid team.

Arc Rated GORE-TEX PYRAD® product technology is a waterproof, windproof and breathable multi-norm compliant lightweight flame-resistant fabric.  In the case of an arc flash exposure, the fabric stops flame propagation by rapidly reacting and forming a stable insulating protective shell of  carbonaceous char with the face fabric (without melting or dripping) Its functional protective mechanism reduces the transfer of heat to the wearers skin and blocks the heat flow from the arc flash exposure making it suitable for an end user who requires protection levels to protection levels to IEC EN ISO 61482-1-2, arc rated to Class 2 (Box test).

Based on arc flash testing according to IEC 61-482-1-1 (open arc test), it offers an incident energy limit value (ELIM) of 42 cal/cm² of protection. Additionally, it is electrostatic dissipative and protects against liquid chemicals. Being up to 50% lighter than other Arc rated Class 2 fabrics in the market, arc rated GORE-TEX PYRAD® product technology is the only solution that offers the perfect balance of multi-norm protection, comfort and durability.

The Procurement Project Team   

The vital importance of multi-protection PPE for Northern Powergrid colleagues was appreciated and understood by the working group. Severe weather protection, as well as the correct electric arc protection were top of mind.

Northern Powergrid identified it would need severe weather arc rated jackets, hoods, salopettes and a number of coveralls. Northern Powergrid assembled a wearer trial team which was made up of lines people, jointers and fitters. Working with the wearer trial team J & K Ross and MSA Bell Apparel listened to their feedback and requests and modified designs. Working closely with the GORE workwear team, GORE-TEX PYRAD® fabric technology was supplied in hi-vis orange. This ensured workers could be safely seen and identified as Northern Powergrid at distance – as other outdoor workers typically wear yellow and had the additional benefit that flying insects wouldn’t be attracted to the orange. 

GORE’S manufacturing brand partner, MSA Bell Apparel, produced small quantities of design prototypes in their UK facility using GORE-TEX PYRAD® fabric, which were fully tested in GORE’s state-of-the-art laboratory testing facilities to ensure they were fit for purpose.

The trial team feedback resulted in design improvement, specific to the worker’s needs, such as a request for a Nelson pocket on the jacket which was large enough to hold a switching book. End users also requested changes to the jacket cuffs so gauntlet gloves could easily be put on over these. A traditional jacket cuff proving too wide to allow this to easily happen. This resulted in a narrower cuff being incorporated into the design of the new jacket.

Only when all members of the procurement project team and the wearer trial team were fully satisfied with the final and fully tested design did the MSA Bell Apparel go into full production.

Chris Ross explained how he welcomed the introduction of GORE-TEX PYRAD® fabric technology to the market: “When it was launched, PYRAD was very much needed in the electrical PPE sector. It’s a brilliant fabric because it’s not stiff or heavy and provides complete comfort and protection.”

In July 2021, MSA Bell Apparel supplied the new issue of hi-vis orange jackets, hoods, salopettes and coveralls to J & K Ross for distribution. Industrial laundering company, phs Besafe supplied  unique bar codes which were then fitted by J & K Ross to every garment and these  were then assigned to every  Northern Powergrid industrial colleague. The bar-coding system allows phs to collect garments from depots, professionally clean and then return them directly back to the individual’s locker.

Harsh Weather Calls for Robust Protection

With 47 years of working at Northern Powergrid , Training Engineer David Reed is perfectly qualified to explain why quality PPE provision is required to cope with the reality of outdoor utility work: “Whatever weather comes we just have to be out in it and working. Weather can be an absolute enemy to utility workers.” 

Outdoor electrical workers are not afforded the luxury of staying indoors when the weather turns harsh. Indeed, extremes of weather, such as heavy storms, gale force winds, hale, snow and driving rain are a reality during autumn and winter months for those working on the front line to maintain, repair or upgrade Northern Powergrid’s electricity network.

The winter of 2021/2022 saw the UK – and Northern Powergrid’s operating area -  exposed to a series of severe and disruptive storms that provided real life testing for the newly supplied GORE-TEX PYRAD® jackets, salopettes and coveralls.

The multi-protection, multi-norm garments needed to do the following:

• offer Class 2 arc flash rated protective properties to IEC 61482-1-2
•  provide flame resistance
• contain antistatic properties: EN 1149-3/-5 
• provide protection against rain: EN 343 class 3/3
• dry out overnight and be ready to wear for the next day
• offer breathability so the inside of garments remained dry/ comfortable
• be comfortable to wear so that the garments are worn correctly by end users
• offer high visibility: EN ISO 20471 HI-VIS orange, which would not fade after laundering
• be durable to withstand the daily challenges of the utility worker  

Questionnaire Feedback

After several months of using their GORE-TEX PYRAD® garments, during some of the most extreme storm conditions to hit the UK for several years, Northern Powergrid’s frontline teams were asked to give their feedback via a questionnaire, distributed by team leaders. The job roles of respondents included:  jointers, apprentice fitters, faults coordinators, field engineers, apprentice cable jointers and overhead lines people working in the north of England covering North and West Yorkshire, Teesside and Humber regions.

Key findings include:

• Half of the respondents regularly work with a harness and at height; of these workers all stated they felt sufficiently warm whilst wearing their garments, 58% felt pleasantly dry and 83% found the ergonomic fit of the garment to be very soft and very flexible.
• The entire cohort, 100%, stated that the garments kept them dry.
• When considering the weight of their protective garments 19% found them to be very lightweight, 81% found them to be a comfortable weight.
• When asked how the GORE-TEX PYRAD® garment compared to their previous garment when worn in heavy rain, 84% found the new garments better, 16% found they functioned at the same level.
• Survey participants were asked to state how long their garments take to dry after being exposed to rain all day. 54% stated it took less than six hours, 30% considered it took less than 12 hours, (with 16% of the cohort unsure of the exact drying time.)

Within the questionnaire, Northern Powergrid team members were asked to state in their own words which design features they most valued about their GORE-TEX PYRAD® garments. The majority of responses related to the lightweight quality of the jacket and the fact they were totally waterproof. Additional responses referenced the design and position of the pockets, that the elasticated cuffs on the wrist help to stop the jacket from rising up when stretching. They also mentioned that the new cuff design meant putting on gauntlet gloves was now easier and that the hi-vis orange colour means that flying insects were not attracted to the jacket.

Individual Interview Feedback

In addition to the quantitative feedback from Northern Powergrid’s workforce, one to one interviews were conducted to gain qualitative insights from the end users.

For apprentice linesman Callam Hickling, 25, the toughest part of his job is being out in bad weather climbing poles with leg garter spikes and a harness, for him, good fitting kit is really important. He explains how he finds working outside in the elements: “Heavy wind and rain doesn’t help. Windchill can be an issue because its cold and windy when you are on top of a pole a good 10 metres, if not more, from the ground.” 

Commenting on his GORE-TEX PYRAD® jacket and salopettes Callam said: “I feel confident that the kit is going to protect me in bad weather. A while ago I worked for 16 hours in the rain and I was bone dry. The kit is dry by the next day for when I needed to next use them.”

When PPE doesn’t perform and isn’t fit for purpose, the impact on the wellness of utility workers should not be underestimated.  Jordan Ellis comments: “If I had gotten wet during those long 16-hour days recently would not have felt the best or particularly good the next day. I would definitely have been full of cold and would have been aching. Because the kit kept me warm, I think this helped my body so I could go out again the next day in the lashing rain and storm.”

Fellow apprentice linesman Bayley Rowlands, 22, noticed the difference in weight between his new kit and his previous issue: “They are really good being waterproof and they don’t let rain soak in.  They are lighter than the old kit  aswell and I do feel the difference in weight. The jacket fits really well and there isn’t any constriction of moment.”

Jordan Ellis, 22, evaluated his new GORE-TEX PYRAD® jacket and salopettes during a major incident before Christmas. Jordan explained the first time he really put his new kit to the test: “During Winter last year, I was wearing both my jacket and the salopettes and I had to climb up a pole because we had a conductor down and it was chucking it down with rain. It was dark because it was 7.30 in the evening by then and still raining. I had everything done up on my kit. I had thought I’d be freezing cold in my kit but I was ok, I got warm.  I was completely dry inside and I was really impressed that the kit was this good. Underneath it felt absolutely fine, bone dry, after a long 16-hour shift.”

Training Engineer David Reed, 63, is well versed to talk about the real hazards of working with live electricity and the need for quality PPE. After 43 years of working in this industry he explained: “I’ve never been exposed to an arc flash. Over the years I’ve seen electric arc and I’ve been close to one when we were on lines that were live and I’ve seen arcs a metre long.  I think the correct kit now will make a difference to the people coming through now so they can protect their bodies against all risks. I think it’s a great thing that Northern Powergrid is investing money in kit for our safety.” 

Conclusion

From the initial set up of the project through to the design modifications and the roll out of the new GORE-TEX PYRAD® jackets, salopettes and coveralls Northern Powergrid, Gore, J & K Ross, MSA Apparel and PHS have worked collaboratively with the focus on the end goal. The resulting fit for purpose waterproof and durable PPE provides Class 2 arc rated protection and lightweight wearer comfort for Northern Powergrid colleagues who work hard all year round on the front-line to provide high level service to its customers.

Sean Johnson, Safety Engineer at Northern Powergrid concludes: “Our teams work hard throughout the year to provide the high quality of service expected of them. They are exposed to the elements and the potential risk of heat, flame and thermal hazards associated with working with live electricity. Health and safety is our top priority and we have worked hard as an organisation to equip them with the durable, multi-norm Class 2 arc protection they deserve so they can remain focused on the task in hand and go home safe and well at the end of their shift.”

To me, Paul Jennewein is like MacGuyver: he has every piece of gear you can think of with him in testing situations. Paul is a product specialist for flame-retardant (FR) mission combat clothing. At the test site, he immediately feels at home and tells me that he wants to test two scenarios that users in the military are exposed to: one is an accident during refueling of a vehicle or aircraft, and the second scenario involves an infantryman who gets caught in the explosion of an improvised explosive device (IED). The tests were performed by a professional stunt team in a controlled environment, secured by fire fighters.

Accident during refueling of military vehicles or aircraft

When refueling vehicles and aircraft under combat conditions at all times of the day and night, fuel frequently spills onto the clothing of the refuelers. Clothing wetted with flammable fuel can subsequently be ignited by contact with an ignition source such as sparks, extremely hot surfaces or the like. A Defense FR rain suit with GORE-TEX PYRAD® technology was tested. Jan Singh simulated this tank accident by spraying the right side of the suit with diesel and gasoline and then igniting it close to the ground by means of a small gas deflagration.

Heat and flames from improvised explosive device

Improvised Explosive Devices (IEDs) unfortunately continue to be a threat for soldiers on missions globally. In this scenario, the effects of the heat and flames caused by an IED on mission combat clothing are examined. Flame-retardant combat uniform made of PYRAD® fabric technology By GORE-TEX LABS, as worn by defense personnel in many European countries, is used. Jan Singh simulated this scene using two large initial gas explosions and a continuously burning gas flame as an additional heat source. Lycopodium was used as an additional fire effect in the background.

Arc-rated GORE-TEX PYRAD® garments protect technicians from high-voltage current

The construction division of Samsung C&T is currently building the world’s largest semiconductor production line in Pyeongtaek, Korea, where the arc-rated GORE-TEX PYRAD® garment was adopted to ensure worker safety for parts of the facilities.

“Safety is the number one principle of management in Samsung C&T. We put priority on providing a safe workplace for our employees. Gore’s arc protective garment was selected due to the superior level of safety and comfort over alternatives.”

To make the final selection, a comparative assessment was conducted based on the feedback of workers exposed to the risk of accidents on site who tried out various options. The assessment covered characteristics such as protection, pleasantness, comfort, lightness, durability, and design. IEC certification was confirmed to see if performance met globally-accepted tests. Lastly, a series of tests were implemented before surveying demand and placing an order.

GORE-TEX PYRAD® stands out in flame retardancy, protecting the body from sudden threats of heat and flame

Technicians were very pleased with the arc protective garment engineered with GORE-TEX PYRAD® technology. They evaluated it to be much lighter compared to existing products, pleasant thanks to moisture permeation, and comfortable. Reliability of safety was another factor for satisfaction, arising from flame retardancy of details such as zippers and Velcro as well as rigorous testing. GORE-TEX PYRAD® also provide excellent tensile strength and color fastness to light and rubbing, making the garment protected against wear and tear, and discoloration.

Arc-rated GORE-TEX PYRAD® garment, the optimal protection against sudden electric arc and flame

According to Samsung C&T’s on-site safety manager, power is shut down before carrying out most electric work. However, workers and supervisors are required to wear an arc protective garment when wiring high-voltage electric switchboards in case of potential risk. On sites dealing with advanced processes, power is turned on in stages rather than all at once to manage wire load, requiring live wire work. An electric arc flash under such a situation will expose technicians to heat above 20,000 ˚C. FR garments and arc protective garments are required for live wire work with an open distribution board or switchboard to protect the technicians.

As verified under IEC 61482-1-1, GORE-TEX PYRAD® is heat resistant, minimizing the risk of skin burns. At the same time, it provides another level of pleasantness based on strong waterproof, windproof, and permeability performances. Users can enjoy great levels of comfort and freedom of movement with 45% lighter fabric over competitors. Furthermore, unparalleled durability based on strong wear resistance and color fastness provides longer life and protection.

Above all, the Gore solution offers improved thermal safety and insulation performance. Thus, the garment maintains its functions even after exposure to heat and flame. Enhanced thermal protection minimizes injuries such as burns. Flame resistance is the property to self-extinguish when flame or heat source disappears. It does not mean that the material does not burn. GORE-TEX PYRAD® is also self-extinguishing, without melting or dripping at high temperature. This is crucial given that dripping is the cause of burn for general synthetic textile. The outstanding thermal safety also helps maintain the lining intact in original form even when the other shell of a laminate is burnt.

The comparative analysis of conventional FR garments and the arc-rated GORE-TEX PYRAD® garment was conducted at the Hwaseong E-PTJ site of Samsung Electronics. Both were donned by workers for technical assessment on performance against electric arc flash, flame, and laminated fabrics. It was confirmed that the Gore product meets the IEC standards with its performance and improved features.

Riot police and closed police units can experience very different deployment scenarios. The majority of operations are peaceful, accompanying law enforcement missions. Increasingly, however, there are also operations in which the law enforcement officers are confronted with massive violence and are also directly attacked. Particularly shocking escalations, such as those that occurred in 2017 at the G20 summit in Hamburg, are just one example of the increased threats during operations. Molotov cocktails that have been seized testify to the fact that the danger of arson attacks directly on officers is real.

There are no defined test procedures for throwing a Molotov cocktail. In order to test "fitness for use" and the protection of GORE-TEX PYRAD® product technology in a simulated emergency, Katja Christof, Product Specialist at GORE-TEX Professional for police clothing, had this situation recreated. Under controlled conditions and with high safety requirements, a Molotov "attack" was simulated.

The instruction to the stuntman was the same as the police operational training: first, grasp the situation, second, find an escape route and actively move away from the fire, and third, extinguish any liquid that may be burning on the surface of the clothing by rolling on the floor or tapping it out. Jan Singh simulated throwing a Molotov cocktail - a gasoline/diesel mixture in a bottle onto the ground in front of the stuntman.

This project was still in its infancy, but it has already caught the attention of everyone involved, as we wanted to test the flame resistance of various GORE-TEX PYRAD® product constructions. Of course, the products are tested extensively in the Gore lab environment before they are used, such as horizontal external flame (EN ISO 15025-A), measurement of transmitted energy and prediction of burn risk using a sensor-equipped manikin (ISO 13056:2017) also known as Pyroman or ThermoMan. These are mostly tests that simulate extreme situations in a standardized test environment. But what happens to the garment in a real, mock end-use situation such as Molotov cocktail attack on a federal police officer. How does the garment look, how does the wearer of the garment feel about it? Initially, we had the idea that we would test it ourselves on a discarded mannequin and record it by means of photographs. 

But then, this was the outcome of the project:

·         two days test trials

·         five different fire situations

·         a professionally trained stuntman team

·         a special effects technology team working for film and television productions

·         three photo and two video cameras

·         plenty of new insights for the GORE-TEX Professional product specialists.

Molotov cocktail & Co.

Specifically, we wanted to test GORE-TEX PYRAD® product designs to see how the technology would perform, for example, in a Molotov cocktail attack on riot police or a refueling accident during a military aircraft refueling operation. But we also wanted to explore the use of technical rescue personnel, for example in a car accident, where liquids can suddenly ignite.

Special effects

After an initial conversation with special effects expert Jan Singh, it was clear that we would do the tests with a professional stuntman instead of a mannequin. The background to this decision was that certain sequences could be simulated much more realistically. With Jan Singh and his team, we had experts at our side who have been producing special effects such as fire, explosions, rain, snow, bullet holes in car windows, and much more for television productions or advertising for 22 years. For our experiments, we needed scenarios that were as realistic as possible, because we did not want to create huge explosions or special effects, as they are often used in Hollywood productions for the sake of entertainment.

Professional stuntman, test site and safety precautions

In order to be able to carry out such scenarios safely, we had to find a suitable location. A gravel pit operator in Bavaria granted us the necessary permission for the tests and - in close collaboration with the Stuntteam Germany - organized the local fire department to supervise the tests. The latter not only provided a professionally trained stuntman, but also took care of additional protection of the stuntman and filmcrew during the tests to exclude any risk of injury.

Test setup

The first day was a trial day. First, we had to discuss exactly the tests we had received based on user feedback with the special effects team and the stunt team. To simulate this, we set up a wooden dummy and tested the respective fire situation directly on the dummy. At the same time, we discussed the situation with the stunt team and instructed the stuntman exactly what to do in which situation. Paul Jennewein, Product Specialist GORE-TEX Professional for Defense, said he had already gained very important insights for his product development on the trial day. Then, on the next day, it was time to implement the five test scenarios. More about this in the next blog post.

Working with electricity in any environment can be highly dangerous. SPIE technicians work at great heights on pylons supporting high-voltage overhead lines, maintain the electrical substations of regional network operators and install lighting or information systems on high ceilings. Operating giant data centres with their huge electricity consumption is no less dangerous. The work of these technicians can have potentially fatal consequences in environments in which they are at risk of exposure to arc flashes. Such incidents arise from electrical arching between two parts of an electrical system. They produce clouds of plasma reaching temperatures of 5,000°C, burning clothing and causing severe burns within milliseconds.

This is why workplace safety is such a major concern. “The company has two guiding principles,” explains Dr Oliver Polanz, head of HSEQ (health, safety, environment, quality) at SPIE Germany and Central Europe. “Firstly, optimising workplace health and safety through leadership, good discipline and a culture of change. Secondly, no compromising when it comes to workplace health and safety.” At SPIE, this also applies to their employees’ workwear: “In situations in which personal protective equipment needs to be worn, it should have an ergonomic fit and be as lightweight as possible,” says Oliver Polanz. “Wearer acceptance is incredibly important when it comes to protective clothing. People will only wear it, if they feel comfortable in it.” The fact that SPIE employees are given a say in health and safety issues is evident in the day-to-day workings of the company. The employees had become increasingly dissatisfied with their existing multinorm workwear. It had a poor ergonomic design and did not offer adequate protection in wet weather. Furthermore, it caused excessive sweating during strenuous work because of poor breathability. One of the outcomes was frequent workplace absences due to colds.

Lightweight: innovative arc rated waterproof garments

The company set about looking for a replacement for their existing foul weather workwear. They conducted a detailed analysis, held consultations with Iturri, their supplier, did their own market research and discussed the issue with leaders and works council representatives. Ultimately, a decision was made in favour of waterproof workwear equipped with the innovative GORE-TEX PYRAD® product technology. This technology is durably waterproof and windproof and thus ideally suited to outdoor work in wind and rain. In addition to the waterproof GORE-TEX membrane, it features two textile layers: the outer fabric with the PYRAD^® by GORE-TEX LABS product technology and an inner lining. This innovative functional fabric means that GORE-TEX PYRAD® protective garments provide the highest level of class 2 electric arc protection. A porous insulating barrier forms on the lightweight outer fabric made of polyester or polyamide within milliseconds of sudden exposure to heat, or the moment at which an electric arc incident occurs. This barrier blocks the convective heat flow during arc exposure and keeps the wearer safe. All this happens “in real-time”. But what makes this solution more comfortable for the wearer? When wet or dry, this innovative material is up to 45% lighter than previously available flame retardant waterproof fabrics. This results in a lightweight garment that is still highly breathable, waterproof and windproof. This is essential because SPIE technicians work outdoors, whatever the weather. They have even been known to work on pylons in wind conditions reaching gale force six.

This fabric technology also allows for the manufacture of protective garments that feature extra benefits to comply with additional standards, such as those covering high visibility, chemical resistance and antistatic protection. There are also all sorts of ways in which the protective clothing can be tailored to suit individual needs. Consequently, SPIE conducted several wear trials before going ahead with procurement. This saw GORE-TEX PYRAD® foul weather garments being tested in strategic areas of the business and at various times of the year. Garment manufacturer Iturri supplied SPIE with various prototypes, each time taking into consideration the suggestions of the trial participants. This approach has certainly led to more wearer acceptance. The new protective garments were either leased or purchased, depending on the needs of the different areas of the company.

For everyday wear: lightweight protective workwear with class 2 electric arc protection

Ordinary foul weather garments do not always provide the level of protection SPIE employees need to go about their work. “There are many sectors in which customers specify that our technicians must wear clothing that complies with the requirements of class 2 electric arc protection,” explains Oliver Polanz. “These workers can find themselves pushed to their limits, especially on hot summer days or in exceptionally hot buildings.” In such situations too much heat can build up inside the garment. In other words, not all foul weather garments produced for protection against electric arc hazards are entirely suitable for everyday wear.

Having seen how satisfied their employees were with the GORE-TEX PYRAD® fabric technology, SPIE decided to try out the same technology in a set of lightweight protective garments intended for everyday wear: when waterproof protection is not required. The first step was to run a series of field tests with arc rated PYRAD® by GORE-TEX LABS garments – a version of the smart technology developed for lightweight protective clothing for daily use. This material is windproof and extremely breathable. It can be worn in comfort all day long, even in dry environments and on warmer days. This is because body warmth does not accumulate inside the garment, not even during physically strenuous activities.

The ingenious thing about this technology is that, for the first time, a special membrane, the lightweight PYRAD® by GORE-TEX LABS - consists of three components in a one ply solution: the outer shell, a wafer-thin non-flammable ePTFE membrane with an incorporated PYRAD® by GORE-TEX LABS technology and a flame-retardant backer. As a consequence, the functional fabric feels thinner and is far more flexible than other options available in this sector. It weighs less than 330 g/m2 and is up to 50 percent lighter than previously available flame retardant textiles, offering significantly enhanced freedom of movement without compromising on protection.

Early field tests revealed that the SPIE workers were just as satisfied with this non waterproof version of the PYRAD® by GORE-TEX LABS product technology: “We had ten sets of clothing on the go. The feedback we received from our workers was overwhelmingly positive,” Oliver Polanz explains. The approach adopted previously with garment manufacturer Iturri had been so successful that the same procedure was used again. It took several months and multiple field tests before the new safety workwear, designed around the specific requirements of the company, was ready for production. These garments were also tested in a wide variety of typical working environments and weather conditions. Iturri manufactured a series of prototypes, each time in the required quantities and reflecting the suggestions of the test participants. Workers can now choose between two alternatives depending on the working environment: the lightweight arc rated PYRAD® by GORE-TEX LABS protective garments for day in day out use and, whenever necessary, the wet weather version, the arc rated GORE-TEX PYRAD® foul weather garments.

To operate effectively, officers need to have full confidence and trust that their gear will protect them from the most extreme risks if a situation escalates quickly.  The GORE-TEX PYRAD® Riot Suit provides reliable protection from sudden incidental heat, flash fire, chemical penetration and inclement weather.

The GORE-TEX PYRAD® Riot Suit is inherently flame retardant and has been proven in independent test to protect the wearer from incidental heat and flash fire associated with petrol bombs and exploding cars. The suit also protects from common chemicals, including gasoline and most diluted acids and alkalis.

Working long shifts outside in in heavy, cumbersome gear can be very uncomfortable for officers. The GORE-TEX PYRAD® Riot Suit is lightweight and wears and feels like regular rainwear, delivering high levels of comfort for long periods of wear outside. It is less stiff and more flexible than traditional fire-resistant fabrics and absorbs less water so that it dries quicker. 

It is vital that officers have the best protection to prevent their concentration levels being inhibited by becoming too hot, wet or cold, hampering their decision making in rapidly changing situations. The GORE-TEX PYRAD® Riot Suit is waterproof, windproof and breathable, keeping the wearer dry from the outside elements while allowing sweat to pass out through the garment in warm conditions. This helps officers to keep their focus on the task at hand.

Katja Christof, Product Specialist at GORE-TEX Professional said: “The new GORE-TEX PYRAD® Riot Suit really is a game changer in personal protection for public order policing. It delivers the critical protection required from the most extreme risks such as incidental flash fire, while at the same time achieving high levels of comfort and freedom of movement. The lightweight fabric eliminates the traditional compromise between comfort and protection in a suit that is designed to achieve consistently high levels of performance throughout its operational lifetime.”

The new suit will withstand the toughest conditions with high resistance to abrasion and almost no pilling, and is available in a wide range of colors.

Gore Associates Paul Jennewein  and Thomas Meyer test immersion protection garments using GORE-TEX PYRAD® product technology from Viking-Life Saving Equipment in Lake Chiemsee, Germany.

Arc rated GORE-TEX PYRAD® fabric is a multi-functional and multi-norm solution for electrical workers who are exposed to the risks of an electric arc, electrostatic discharge and who often have to operate in foul weather conditions. Today, GORE-TEX Professional announced the introduction of a concept for arc-rated 3-layer overtrousers to its PYRAD® portfolio of products. Trousers utilising arc rated GORE-TEX PYRAD® fabric technology allow end users to stay Class 2 arc protected, dry, comfortable and focused on their work not their PPE. When compared to other Class 2 arc protection rainwear trousers currently available they are significantly lighter, less bulky and, in fact they are exceptionally comfortable to wear, remain dry on the inside and provide quick re-drying properties.

The concept of arc-rated overtrousers is constructed from GORE-TEX PYRAD® which is a 1-ply fabric with 3 layers: a face fabric, GORE-TEX membrane plus PYRAD® fabric technology and a flame-retardant backer. To support the introduction of this new technology to our partners, the GORE-TEX Professional design team has developed a new concept for overtrousers that is durable to stand up to tough working environments and designed so that they are easy to put on over existing non-weather protective clothing. The beneficial and functional design elements include: pre-shaped legs, safety zips which run from the hem to the knee so there is no need to remove safety boots to get them on or off and the back is shaped higher than the front to ensure all day wearer comfort in all working positions. As part of their concept design program, GORE-TEX Professional provides this overtrouser design as a service to customers.

Importance of protecting your legs

Legs account for approximately 36% of the body’s total surface area, once they become wet or cold this can impact on the overall warmth and well-being of the rest of the body. It is well documented and scientifically proven that chilled legs put a strain of the immune system. In addition, cold leg muscles have a higher risk of sustaining injury because muscle strength decreases as temperatures fall. GORE-TEX PYRAD® 3-layer overtrousers tackle such issues head on because they provide durable waterproof and windproof protection against rain and wind, which is key to preventing the wearer from getting wet and cold.

Arc rated GORE-TEX PYRAD® 3-Layer overtrousers are a protective and intelligent choice for all electrical workers who demand and deserve the following wide range of protective features: Class 2 arc rated protection, weather protection, flame protection, protection against the hazards of an electric arc, protection against electrostatic discharges and highly visible functionality.

In the electrical engineering industry, an awareness of standards of safety wear has by necessity and law been around for some years, with research, new product developments and new standards emerging in this ever-developing field. Protecting engineers exposed to electrical hazards whilst carrying out their daily work is paramount. Electric arc standards are not only subject to change from time to time but can be a source of confusion and doubt for employers who have a duty of care to their employees. Employers must ensure that risk assessments and the resulting PPE specifications are correct for each working scenario.

Key points and facts about electrical arc protection.

1. THERMAL ARC PROTECTION IEC 61482-2 this is the basic legal requirement for PPE in this sector and thus of crucial importance. It is the key standard that covers protective clothing against the thermal arc hazards of an electric arc. The IEC 61482-2 standard includes various aspects of garment design and employers must only procure PPE which carries this level of arc flash protection. In order for a garment to reach or exceed the requirements of this IEC standard it must pass one or ideally both test methods used for testing the clothing and material.  These can be separated into EN 61482-1-1 known as the Open Arc Test Method and EN61482-1-2 known as the Box Test Method.

2. THE OPEN ARC TEST is a method for determining the Arc Thermal Protection Value (ATPV) of a garment, based on the Stoll Curve, which is itself a graph that shows the point at which greater protection should be provided in order to avoid injuries due to heat energy transfer levels. The ATPV shows how much thermal energy any arc flash PPE can withstand to avoid the wearer getting second-degree burns. Thus, the Open Arc Test produces an arc rating.

3. ATPV/EBT RATING this is, simply put, a measurement of a fabric’s ability to protect an individual from a burn due to exposure to incident energy resulting from an arc flash. This thermal resistance rating is measured in calories per square centimetre. Arc Ratings are calculated using at least 20 data points and a logistic regression to determine the incident energy level of a 50% probability that there is enough heat transfer to cross the Stoll Curve (ATPV), or for the material to break open and create exposure, called EBT or the Energy Breakopen Threshold. The higher the numerical rating/value, the higher the level of protection.

4. ELIM VALUE – this stands for Incident Energy Limit Value and has been added to the 2019 revision of the IEC 61482-1-1 Open Arc Test standard. The ELIM value is defined as the numerical value of incident energy attributed to a product below which all product responses are below the Stoll curve and without break open. The ELIM is calculated as the average the three highest incident energy data points just below the so-called mix zone. The “mix zone” is the range in testing between the lowest incident energy level that crossed the Stoll Curve, and the highest incident energy level that did not cross the Stoll Curve.

5. BOX TEST METHOD is another method of testing using electrodes arranged in a particular order in a box to produce the electrical arc. This method of testing does not produce an arc rating per se. Rather, it determines the Class Rating of specific garments. Protective wear passing this test will be rated Class 1 or Class 2.  The Box Test standard defines two testing conditions, Class 1 and Class 2, according to different arc incident energy levels.

6. BOX TEST CLASS 1 tests at an arc current of 4kA and a duration of 500ms. This classification is given when clothing material and material pass the test of lower level of simulated arc exposure which is carried out in laboratory conditions.  PPE at this level is the basic requirement and affords a lower level of protection to end users.

7. BOX TEST CLASS 2 a higher test than Class 1, tests at an arc current of 7kA and a duration of 500ms, so PPE at this level is more secure. Class 2 is attributed to clothing material and clothing when both pass the performance criteria in laboratory conditions at the higher level of arc exposure.

Today, innovations are being made in regard to providing Class 2 PPE which is lightweight, breathable and provide comfort to the wearers, such as new Arc Rated GORE® PYRAD® Protective clothing for everyday wear. Understanding the levels of protection needed to ensure the adherence of the best and highest safety levels required for workers at risk of the potential dangers of arc related incidents need not be confusing. Keeping up to date on the key terms, safety tests and new protection standards, mentioned here, is a firm step in the right direction. It is always advisable to engage with established and trusted PPE manufacturers who will guide through wearer trials and the procurement process.
