Prevention of arc flash events is the key and the top priority of electrical safety at work place. It is first
line of defense.
However, burn trauma centers are still receiving patients injured in electric arc. And what would be the second
or protection line of defense?
Which "domino" you would push first to
have the “domino effect” that would lead to a reliable protection against thermal effects of electric arc. Is it a safety program? Or engineering study of your electrical system
with arc flash capsulations? Or properties of a materials used for thermal protection? Or arc testing of PPE? Or the personnel training to lean what work practices are the best to avoid
injury?
Well, may be just having a close look at
the object of protection – electric arc itself. Latest results of research work, accident investigation show that not all arcs are “burn” even. There are different types of arc behavior that result
in hazard differences. Knowing electric arc properties, we can better design PPE, test methods and work practices.
