What is NFPA 70E?

NFPA 70E, Standard for Electrical Safety in the Workplace®, establishes requirements for protecting employees from electrical hazards associated with the installation, operation, maintenance, and repair of electrical equipment. The standard provides a framework for implementing electrical safety programs, performing risk assessments, establishing safe work practices, and protecting qualified workers from arc flash and shock hazards.

An effective electrical safety program helps organizations identify and reduce workplace electrical hazards through engineering analysis, documented procedures, employee training, appropriate personal protective equipment (PPE), and ongoing program management. By implementing consistent electrical safety practices, facilities can improve worker safety, reduce operational risk, and support compliance with current electrical safety requirements.

Core elements of an effective NFPA 70E program

Protecting employees from electrical hazards requires more than Power System Studies alone. NFPA 70E promotes a comprehensive approach to workplace electrical safety through documented programs, hazard assessments, employee training, safe work practices, and ongoing evaluation of electrical systems. Organizations should regularly review these core elements to strengthen electrical safety programs and support compliance with NFPA 70E.

  • Electrical safety program

Establish and maintain a documented electrical safety program that defines responsibilities, policies, procedures, and safe work practices for employees who work on or near electrical equipment.

  • Safe work practices

Develop procedures that prioritize establishing an electrically safe work condition whenever possible and define the controls required when energized work cannot be avoided.

  • Personal Protective Equipment (PPE)

Select and maintain PPE appropriate for the identified electrical hazards and the results of arc flash and shock risk assessments.

  • Arc flash risk assessments

Evaluate electrical systems to identify arc flash hazards, determine incident energy levels, establish arc flash boundaries, and identify appropriate protective measures before energized work is performed.

  • Employee training

Provide ongoing training so qualified and unqualified employees understand electrical hazards, safe work practices, personal protective equipment (PPE), and their responsibilities under NFPA 70E.

  • Equipment maintenance

Maintain electrical equipment in accordance with manufacturer recommendations and applicable standards, recognizing that properly maintained equipment contributes to safer operation and more accurate hazard assessments.

FAQs



Is NFPA 70E required by OSHA?

While OSHA does not adopt NFPA 70E as a regulation, the standard is widely recognized as a best practice for electrical safety in the workplace and is frequently referenced to help organizations develop electrical safety programs and safe work practices.

Does NFPA 70E require an arc flash study?

NFPA 70E requires employers to perform an arc flash risk assessment. Arc flash studies provide the analysis used to determine incident energy levels, arc flash boundaries, and equipment labeling that support those assessments.

How often should an arc flash study be updated?

NFPA 70E recommends reviewing and updating arc flash studies at intervals not to exceed five years or whenever significant changes are made to the electrical distribution system.

How often should arc flash labels be reviewed?

Arc flash labels should be reviewed whenever an arc flash study is updated or when modifications to the electrical system could affect incident energy calculations or equipment labeling.

Who should receive NFPA 70E training?

Employees who may be exposed to electrical hazards should receive training appropriate to their job responsibilities. Qualified persons require additional training on electrical hazards, safe work practices, PPE, and risk assessment procedures.

What is considered a qualified person under NFPA 70E?

A qualified person has demonstrated the skills and knowledge necessary to recognize electrical hazards, understand the construction and operation of electrical equipment, and safely perform assigned work in accordance with NFPA 70E.

What is the difference between an arc flash study and an arc flash risk assessment?

An arc flash study is an analysis that calculates available fault current, incident energy levels, arc flash boundaries, and equipment labeling requirements based on the electrical distribution system. An arc flash risk assessment, as required by NFPA 70E, uses the results of the arc flash study along with the specific work task, equipment condition, and likelihood of occurrence to determine appropriate risk reduction measures and personal protective equipment (PPE) requirements before work is performed.
