NFPA® 70E-2018 standard for electrical safety requirements
The National Fire Protection Association® 70E® standard covers most workplace activities related to electrical energy or equipment. The 2018 edition continues to focus on risk assessment and introduces human factors, such as human error, as part of the assessment. Emphasis is now placed on the hierarchy of risk controls methods: 1) Elimination; 2) Substitution; 3) Engineering controls; 4) Awareness; 5) PPE.
Major exceptions are vehicles, such as ships, aircraft, and railway rolling stock; railway electrical systems used exclusively for the operation of rolling stock or installations, or used exclusively for signaling and communications; communications equipment, under the exclusive control of communications utilities, and located outdoors or in buildings used exclusively for such installations; and certain electrical installations under the exclusive control of an electric utility.
