What material must be worn under ARC flash PPE?

You have a couple of choices regarding undergarments when dressing for ARC flash applications. Underwear and t-shirts made from 100% cotton is an option since cotton won't melt onto the skin when exposed to high heat and flame. Another choice is to wear fire retardant undergarments designed specifically for welding and other similar tasks.

How do I dress properly to protect against ARC flash injuries?

ARC flash injuries can cause long-term damage, and its important to make sure that you're fitting your PPE correctly to provide the best protection. Choose fire retardant undergarments and tuck them in to ensure the maximum coverage of the skin. ARC flash coveralls, jackets and trousers should be completely closed with all zip closures and button fastenings used. Cuffs should be tucked into ARC flash safety gloves, and the same should be done with trouser or overall seams into welding safety boots. Welding masks and neck protection should be fitted properly, with the skirting overlapping the shoulders and chest where possible.

Once dressed in the ARC flash PPE, no skin or non-fire-retardant materials should be exposed. Take a look in the mirror or get a colleague to check you're completely covered.
