What is Arc Flash?
An arc flash is a release of energy caused by an electric arc. The flash causes an explosive expansion of air and metal. The blast produces:
A dangerous pressure wave
A dangerous sound wave
Shrapnel
Extreme heat
Extremely bright light
These dangers can result in blast injuries, lung injuries, ruptured eardrums, shrapnel wounds, severe burns and blindness. Arc Flash injuries can also result in death. Statistics gathered by the Ontario Ministry of Labour show that arc flash injuries represent a large percentage of the electrical injuries that occur in Ontario Workplaces. The nature of an electrical worker’s job can put the worker close to energized electrical equipment. As a result, electricians can be exposed to an arc flash during the course of a normal work day.
