An electrical arc-flash is a hazardous electrical explosion caused by faulty conditions or a short circuit that can reportedly generate temperatures of up to 35,000ºF—nearly four times the temperature of the surface of the sun. The dangers associated with arc-flash include severe burns and even death.

Avoiding tight fitting clothing is essential if that clothing is being worn to protect you against the thermal effects of an arc flash. NFPA 70E states that the worker must avoid tight-fitting arc flash gear and that loose fitting clothes provide more thermal protection because of the “air spaces.”

What is an Arc Flash and How Can an Arc Flash Happen? An arc flash is an undesired electric discharge that travels through the air between conductors or from a conductor to a ground. The resulting explosion can cause serious harm to people, fires and damage to equipment. The arc flash occurs during a short circuit.

The implementation of an Arc Flash Risk Assessment can be segmented into three project phases. These may be described as Phase 1 – Data Collection, Phase 2 – Engineering study (Electrical system analysis), and Phase 3 Electrical Safety Program implementation. Beyond building this “baseline project”, there also should be plans for ...

The arc flash and blast will likely vaporize all solid copper conductors. These conductors expand up to 67,000 times their original volume when vaporized. The arc flash and blast produce fire, intense light, pressure waves, and flying shrapnel. When an arc flash happens, it does so without warning and is lightning quick.
