Codes and Standards

Below you will find information about the codes and standards you need to know about for arc-flash hazard compliance.

OSHA 29 CFR 1910.132(d)
Requires employers to assess the workplace to determine if hazards are present or likely to be present, and select and have each employee use the types of PPE that will protect them. See this regulation at osha.gov

Standard Interpretation 11/14/2006 - OSHA requirements for warning signs and protection from electric-arc-flash hazards and compliance with NFPA 70E-2004.

Addresses the following questions:

"When work must be performed on energized electric equipment that is capable of exposing employees to arc-flash hazards, does OSHA require the marking of the electric equipment to warn qualified persons of potential electric arc-flash hazards — i.e., as required by NFPA 70E-2004?"

"Is flame-resistant clothing required for employees working on electrical installations covered by Subpart S?"

"How is OSHA enforcing §1910.132 and Subpart S with regard to the latest edition of NFPA 70E requirements?"

"Does OSHA issue Section 5(a)(1) General Duty Clause violations to companies who do not follow the new NFPA 70E requirements?"

2009 NFPA 70E Section 130.3(B)
Requires that an arc-flash hazard analysis be performed and documented to determine the incident energy exposure of the worker, the flash protection boundary and that PPE is used based upon the hazard associated with a task. A revision for the 2009 edition states that "arc flash hazard analysis must be revised at intervals not exceeding 5 years."

National Electrical Safety Code (NESC) ANSI C2-2007, Section 410.A.3
Requires all employers to perform an arc-flash assessment by January 1, 2009. IEEE does not provide a free online copy of their standards. You can order a copy through our Technical Resource Center or contact us to discuss these NESC requirements.

The IEEE is currently undertaking a survey of all Public Service Commissions, Public Utility Commissions, or other appropriate state regulatory bodies to determine the edition of the NESC in effect in each state and how that adoption is promulgated.
