An electric arc is a continuous electric discharge of high current between conductors, generating extremely bright light and intensive heat. The arc blast presents a serious hazard (potentially fatal) to employees due to the risk of severe burn injuries caused by the intensive heat.
Permanent protection from non-flammable fibre
DuPont™ Nomex® fibre is inherently flame-resistant, will not melt or drip,and does not support combustion in theair, thus providing excellent arc flashprotection. And because the protection iswoven straight into Nomex® garments, itcannot wear off or wash out over time.When exposed to flame, the man made high-performance aramid fibres wells, becoming thicker and forminga protective barrier between the heat source and skin. This protective barrier stays supple until it cools, helping togive the wearer vital extra seconds of protection to reach safety.
