Electrical self-inspection checklist

Electrical current exposes workers to a serious, widespread occupational hazard. Many workers are unaware of the potential electrical hazards present in their work environment, making them more vulnerable to the danger of electrocution. Electrical injuries consist of four main types: electrocution (fatal), electric shock, burns, and falls caused as a result of contact with electrical energy.

The Occupational Safety and Health Administration (OSHA) provides requirements for electrical safety in general industry within 29 CFR 1910.302 through 1910.399. NFPA 70, National Electrical Code (NEC), 2014 Edition and NFPA 70E, Standard for Electrical Safety in the Workplace, 2015 Edition, published by the National Fire Protection Association (NFPA), provide detailed requirements for electrical installations and safety when working around electrical equipment. This checklist can be used to help identify common electrical hazard concerns and best practices, but should not be used as a substitute for compliance with OSHA regulations or NFPA codes and standards. Any question answered “No” should be thoroughly investigated and corrective actions taken.
