An arc flash is defined as a hazardous explosion of energy from an electrical circuit, or a type of discharge that results from a low-impedance connection through air to ground or to another voltage ...

This is the final installment of a three-part series on the importance of arc flash labeling of electrical equipment. In Part 1, which ran in the September 2011 issue, we considered the low-level task ...

Electricians face many challenges on the job, including shock, electrocution, arc flash, and arc blasts, all of which can cause lasting injuries or death. Construction electrical work is considered ...

An arc flash occurs due to a phase-to-ground or phase-to-phase short circuit. The extreme heat, light, and pressure blasts associated with these events make it necessary to take precautions when ...

Arc flashes present a serious hazard involving electrical equipment that is more common than many would believe. Due to OSHA’s reporting requirements for arc ...

Every day, an estimated five to 10 arc flash incidents occur and more than 2,000 people are hospitalized each year, according to The National Fire Protection Association (NFPA). With arc flash and ...

Incident energy is directly proportional to the total arcing time. Because of this, most strategies for arc flash hazard mitigation focus on faster detection and clearing of the arc flash. The two ...

Electrical crews rarely operate in ideal conditions. Most of the time, crews are making repairs and improvements in vast, open spaces. That makes workers more vulnerable to risks and hazardous ...
