Flame resistant protective clothing addresses the essential issue of guarding against open flames and sudden flashes. These include things like arc flashes, arc blasts, fires, explosions, and related burns.The two most common hazards Flame Retardant clothing and garments protect against are flash fires and electric arc flash, which we cover in-depth on dedicated resource pages.
Open flames are defined as devices such as candles, boilers, heating units, torches, butane burners, and any other flame producing device. Anyone working around open flames, such as those operating portable torches, should be wearing FR coverall.
Hot work is any process involving flame, spark, or heat production. This includes cutting, burning, welding, grinding, chipping, drilling, and torch-applied roofing. The National Fire and Protection Associations NFPA shows the following workers most at risk for this hazard: construction contractors, ironworkers, sheet-metal workers, roofers, pipe-fitters, utility workers, plumbers, electrical workers, and welders.
Electric current passes through the air between ungrounded and grounded conductors. Temperatures may reach 35,000°F. Electricians and electric utility linemen are those who need to pay close attention to 70E updates and HRC levels.
