NFPA 70E, titled Standard for Electrical Safety in the Workplace, is a standard of the National Fire Protection Association (NFPA). The document covers electrical safety requirements for employees. The NFPA is best known for its sponsorship of the National Electrical Code (NFPA 70).
NFPA 70E addresses employee workplace electrical safety requirements. The standard focuses on practical safeguards that also allow workers to be productive within their job functions. Specifically, the standard covers the safety requirements for the following:
- Electrical conductors and equipment installed within or on buildings or other structures, including mobile homes, recreational vehicles, and other premise (yards, carnival, parking lots, and industrial substations)
- Conductors that connect installations to a supply of electricity
Not covered are - electrical installations in marine or aircraft, auto vehicles, communication & electrical utilities.
Key principles covered are shock protection boundaries, arc flash energies, Lockout-Tagout, PPE (Personal Protective Equipment). While the various OSHA, ASTM, IEEE and NEC standard provide guidelines for performance, NFPA 70E addresses practices and is widely considered as the de-facto standard for Electrical Safety in the Workplace.
