Arc flash incidents often injure untrained personnel
Electrical injuries are among the construction industry's “fatal four” that caused more than half of construction deaths in 2013, according to OSHA's website.
Arc flashes, which the Workplace Safety Awareness Council said cause about 7,000 burn injuries a year and hospitalization costs ranging from $200,000 to $750,000, happen when electrical current travels through the air from one conductor to another or to the ground.
