Arc flash is the term describing an extremely dangerous electrical hazard when uncontrolled current passes between two conductors. When voltage is high enough (over 480V), the intense heat of the arc ...

Arc flashes occur when electrical current jumps the gap between two or more energized conductors. Depending upon the amount of current, arc temperatures can exceed 35,000 degrees F. That’s why ...

A few years ago, the term “arc flash” crept into our electrical technical vocabulary. Since that time, performing arc flash calculations remains a challenge for many of us. Calculating incident energy ...

The Occupational Safety and Health Administration (OSHA) has begun to aggressively monitor compliance with passage of the National Fire Protection Association's (NFPA) 70E standard, issued in 2000. In ...

OSHA's job is to ensure safety in the workplace, but in many cases, the agency leaves the methods for achieving safety to other standard-setting bodies. An excellent example of this arc flash safety.

In the electrical industry, and the workplace in general, the phrases "arc flash" and "hazard risk analysis" are generating much interest and attention. Many managers and supervisors are asking "why ...

Arc flash is defined as an explosive release of energy caused by an electrical arc. Typically, the arc results from either a phase-to-ground or phase-to-phase fault created by many possible events.

Industrial and commercial operations are faced with mitigating arc flash incidents associated with low- and medium-voltage circuit breakers, while also meeting government/industry electrical safety ...

The new lift-front face shield of this hood provides a larger viewing area through which users can see the energized equipment. By enhancing the area of view to see potential hazards and users’ ...
