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 publishing the
National Electrical Code (NFPA 70).
Purpose
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 premises (yards, carnivals, parking lots, and industrial
substations)
# Conductors that connect installations to a supply of electricity
Not covered are - electrical installations in marine, aircraft, auto vehicles, communications and electrical utilities.
Key principles covered are JSA/JHA/AHA procedures to ascertain shock protection boundaries,
arc flash incident energy expressed in calories/cm2,
lockout-tagout, and
personal protective equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, e ...
. 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.
Practices include
- staging a "safe work zone" with boundaries, barricades, signs and attendants.
- proper body positioning to reduce ergonomic risk, use of rescue hooks in Medium Voltage switching.
- human factor analysis, written procedures to reduce incidents not otherwise imminent from above.
