What is arc flash safety?
The NFPA defines an arc flash hazard as “A source of possible injury or damage to health associated with the release of energy caused by an electrical arc.” In other words, if an arc fault could occur which has enough energy to cause substantial damage, injury, fire or other harm, there is an arc flash hazard.
What happens during an arc flash?
Arc flash is the light and heat created from an arc fault explosion. Temperatures of an arc flash can reach as much as 2,800 to 19,000 °C (5,000 to 35,000 °F). The arc flash can also melt metal, cause lung and eyesight damage and even lead to hospitalization or death.
Who needs an arc flash study?
