OSHA outlines its violations online at, but these terse reports do not address causes. Rather, they highlight the hazard violation: unexpected energization, working near live equipment without training, exposure to electrical shock hazards, and unguarded parts of live electrical equipment. These alone encompass a "who's who" of what can go wrong in a plant when the focus on safety wavers. They also paint a disturbing picture of the poor safety condition in which plants can sometimes find themselves.
