Big Bill FR HRC1 Nomex IIIA 4.5 oz Plain Weave Coverall

Nomex® IIIA
General Garment Information....

Garments of Nomex® consistently provide outstanding thermal performance because Nomex® IIIA:
-- Is inherently flame resistant
-- FR apparel made with Nomex® helps protect against heat and flames
-- Provides permanent flame resistance that won't wash out or wear away.
-- Minimizes break-open and maintains a stable, inert barrier between the fire/arc and skin, protecting the wearer from direct exposure
-- Forms a tough, protective char when exposed to flame, and stays supple until it cools
-- Meets NFPA 1975 for firefighters’ stationwear
-- Meets the ASTM F-1506 standard for workers’ apparel as protection from electric arc exposure.
-- Complies with NFPA 70E Standard for Electrical Safety in the Workplace
-- Complies with NFPA 2112 Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire

Garments made with Nomex® thermal technology are extremely durable and resist abrasion, tears and chemicals.  They’re also an excellent value, lasting three to five times longer than other standard and protective fabrics, including 100% cotton and flame-retardant treated (FRT) cotton. Garments of Nomex® are as comfortable to wear as other work clothing. Lightweight, breathable fabrics of Nomex® brand fiber are designed to transport moisture away from the skin, which helps wearers feel cool and dry. Side-by-side wear tests show that fabric weight is the single greatest factor in controlling garment comfort, and that the lightweight comfort of Nomex® is often preferred over other protective fabrics.
