FAQs

How does an "arc flash" occur?

An "arc flash" is caused by a fault in an electrical circuit that creates a low-impedance path for current to flow through the air. This can be triggered by accidental contact, insulation failure, or equipment malfunction.

What are the primary dangers associated with an "arc flash"?

The dangers include severe burns, electric shock, pressure waves (blast), flying debris, intense light, and deafening sound. These can result in serious injury or death.

What is the difference between "arc flash" and "arc blast"?

"Arc flash" refers to the light and heat produced by an electrical arc, while "arc blast" is the pressure wave resulting from the rapid expansion of air during the arc flash. They occur simultaneously but have distinct effects.

How can I protect myself from an "arc flash"?

Protection methods include wearing appropriate personal protective equipment (PPE) such as flame-resistant clothing, gloves, and face shields; maintaining equipment properly; and following safe work practices. In many cases, the best practice is to de-energize equipment before working on it.
