The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) has cited ASARCO – a metal smelting company – for electrical hazards after an arc flash caused three workers to suffer severe burns at its facility in Hayden, Arizona. The company faces $278,456 in penalties for two willful violations and one serious violation.

OSHA inspectors determined the arc flash occurred after the insertion of a breaker into a 4,160-volt switchgear. OSHA cited the company for its failure to provide a pre-job briefing before work began on the energized switchgear, render the electrical breaker inoperable before work began, and ensure the injured employees had arc-flash protective clothing.

“Employers must not jeopardize the safety of workers,” said OSHA Regional Administrator Barbara Goto, in San Francisco, California. “Arc flash hazards are well known, but can be eliminated when workers are properly trained and protective equipment is provided.”
