All about arc flash: definitions, dangers, stats, causes and prevention
Definitions and Statistics
According to the National Fire Protection Association (NFPA), arc-flash is an electric current that passes through air when insulation or isolation between electrified conductors is no longer sufficient to withstand the applied voltage. The flash is immediate, but the result of these incidents can cause severe injury including burns. Each year more than 2,000 people are treated in burn centers with severe arc flash injuries.
