Flame Retardant FAQs

FR clothing buys time. It either won't ignite at all, or stops burning the moment the heat source is removed. Ordinary clothing doesn't do that, and that's where serious burn injuries happen. The protection comes from one of two places: fibres that are non-flammable by nature (inherent FR, like Nomex or modacrylic), or fabric that's been chemically treated to resist flame. Inherent FR lasts indefinitely. Treated FR can degrade with repeated washing.

EN ISO 11612 is the one to know. It covers heat and flame protection across convective, radiant, contact heat, and molten metal splash. For welding, EN ISO 11611 applies, with Class 1 for standard work and Class 2 for higher-risk processes. If there's also arc flash or electrostatic hazard on site, EN 1149-5 may be needed on top. The certification number on the label matters. "Flame retardant" on its own, without a standard behind it, isn't enough.

When two risks overlap: needing to be seen, and needing fire protection. Standard hi-vis is almost always polyester, and polyester melts in a flash fire, which makes it a hazard in itself. Dual-certified FR hi-vis is the answer for rail workers (where GO/RT 3279 may apply), oil and gas, utilities, and construction sites near gas mains or live electrical infrastructure. If the risk assessment flags both, standard hi-vis doesn't cut it, you’ll need flame retardant hi vis workwear.

Any role where a risk assessment identifies thermal hazard. The list includes welding, foundry work, oil and gas, electrical and arc flash environments, steelworks, rail maintenance, chemical processing, and utility work. It's not only the person at the heat source either. Workers in the vicinity can be in the risk zone too, and that needs to be factored in.

Follow the care label. Bleach and fabric softener are the two things to cut out completely; both strip FR treatments, sometimes without any visible sign. Treated FR fabrics typically have a service life of around 50 washes before protection drops off; inherent FR fabrics don't have that problem. Check the garment before every shift, and replace anything damaged or contaminated (don't patch and carry on).
