An Arc Flash is an electrical explosion resulting from a low impedance connection to ground or another voltage phase in an electrical system. High temperatures cause rapid heating of surrounding air and extreme pressures, resulting in an arc blast.

Risks associated with arc flash include burns and injury due to heat, flying objects, and pressure blasts. While it’s not always possible to completely prevent arc flashes, you can take steps to greatly reduce the likelihood of someone suffering a serious injury or death. 

Most Arc Flash Incident can be avoided with proper training, planning, job preparation, procedures, and equipment in place.
