NFPA 70E requires an evaluation of the arc flash hazard level at each piece of electrical equipment. It also calls for a clear posting of the Personal Protective Equipment (PPE) required to work on each piece of equipment while energized.
An arc flash is a type of electrical explosion that results from a low impedance connection to ground or another voltage phase in an electrical system. There are steps that can be taken to lessen the severity of an arc flash in the event that one does occur.
Allegheny Field Services has extensive knowledge when it comes to arc flash mitigation. AFS has the ability to install devices on existing pieces of equipment that can clear a breaker in a shorter period of time, thus doing less damage to individuals and property.
