The intense energy and very short duration of an electric arc flash represents a very unique exposure — one that requires flame resistant garments durable enough to withstand temperatures that approach 35,000 °F. Once ignited, regular cotton or poly/cotton work clothes can continue burning even after the source of the ignition is removed. But Westex brand fabrics will self extinguish and provide guaranteed flame resistance for the life of the garment. See the videos and charts for proof of Westex fabrics’ superior FR properties.
This video explains how arc flashes happen, how they are measured and how wearing the right FR clothing can keep workers safe and in compliance with industry standards.
