Working in hazardous environments exposes you to many risks, including injuries from flames and electric arcs. That’s why it’s crucial to wear protective FR workwear designed to resist ignition and slow flame spread. But you likely have questions about how these specialized garments actually keep you safe. Read on for answers to some frequently asked questions about fire-resistant clothing.
What Fabrics Are Used to Make Fire-Resistant Workwear?
The key to FR workwear is fabrics made with fire-resistant fibers blended with natural fibers like cotton or wool. Common fire-resistant materials include modacrylic, treated cotton, FR rayon, FR linen, carbonized fibers, and fiberglass. These fabrics resist ignition, self-extinguish when exposed to flames, and are less conductive of heat. Popular name brands for these FR textiles include NOMEX, Tecasafe, Kermel, BASOFIL, and Lenzing FR.
How Is Fire-Resistant Clothing Tested?
Before being approved for use as personal protective equipment, or PPE, FR fabrics and garments must meet strict industry testing standards. Examples include NFPA 2112 and EN ISO 11612, which expose materials to intense heat and open flames to test for limited flame spread, charring behavior, residual heat release, and other measurements. Only clothing that passes and carries certifications based on these tests gets to be called FR workwear.
Does Fire-Resistant Clothing Require Special Care?
To retain its fire-resistant properties even after repeat cleaning and wear, FR workwear does require the following specific laundering instructions. Key things to avoid are fabric softeners, chlorine bleach, and washing with common clothing, which can compromise the fire-resistant treatment. Tumble drying and hot pressing should also be avoided. With proper FR-specific cleaning and care, however, certified FR garments maintain protection for the expected lifetime declared by the manufacturer.
Why Wear Fire-Resistant Clothing Under Non-Fire-Resistant Outerwear?
In some professions, you need protective outerwear that provides water resistance or other attributes not offered by FR fabrics. That’s why the layered approach is recommended: certified FR garments, including shirts, pants, and underwear closest to the skin, then non-FR outershells like raincoats or winter parkas on top. This ensures your FR gear’s thermal and flame resistance continues actively working to help protect and self-extinguish if it’s exposed to sparks or flames.
Do I Need Fire-Resistant Clothing For Electrical Arc Protection?
Exposure to dangerous electric arc flashes is another significant risk in many workplaces. While fire-resistant textiles provide some arc protection, clothing designed specifically for this threat should be worn. Arc rating is measured differently than simple flame resistance. Garments like arc flash shirts and pants, arc flash hoods, and other gear must carry an ATPV or HRC rating indicating the level of protection they deliver. Your arc flash risk assessment dictates the minimum rating required.
How Often Does Fire-Resistant Clothing Need Replacing?
Unlike normal garments, FR workwear is classified as personal protective equipment vital to your safety. As they wear from use and laundering, fabrics lose durability and protective qualities over time. That’s why FR standards include maximum laundering cycles, typically 50 commercial or 100 home washes. Garments should be retired and replaced once they reach these thresholds, as indicated by special tracking labels. Workwear showing damage like tears or holes should be taken out of service more quickly.
What Role Does Fire-Resistant Workwear Play in Multi-Hazard Protection?
Today’s high-performance FR workwear leverages innovative fabrics and designs to provide protection beyond basic flame and heat dangers. Multi-threat garments add enhanced tear strength, electric arc ratings, static control properties, UPF sun protection, high-visibility colors, and more. Combining FR workwear compliant to NFPA 2112 or similar with other PPE gives you reliable defense against multiple hazards in a single layer. That convenience empowers you to work confidently even in complex, risky environments.
Here’s answers to some top frequently asked questions about fire-resistant and arc flash protective workwear. Remember that not all FR clothing delivers equal protection, so always look for genuine certification. Getting properly outfitted in multi-threat garments tailored to your specific risks allows you to focus on doing your hazardous job safely.
