OSHA Standards 29-CFR, Part 1910. Occupational Safety and Health Standards. 1910 sub part S (electrical) Standard number 1910.333 specifically addresses Standards for Work Practices and references NFPA 70E.

OSHA 1910.132(d), and 1926.28(a) states that the employer is responsible to assess the hazards in the work place, select, supply, and require the use of the correct Personal Protection Equipment ( PPE ), and document the Arc Flash Analysis results. OSHA considers the NFPA 70 and 70E standard a recognized industry practice. And the administration’s field inspectors carry with them a copy of the NFPA 70E and use it to enforce safety procedures related to arc flash.

The employer is required to conduct and Arc Flash Hazard assessment in accordance with OSHA 29CFR1910.132(d)(1). Employers who conduct the hazard/risk assessment, and select and require their employees to use PPE, as stated in the NFPA 70E standard, 2004 Edition, are deemed in compliance with the Hazard Assessment and Equipment Selection OSHA Standard. In addition, The NFPA 70E 2004 indicates that any electrical enclosure likely to be serviced by an employee or worker, have an Arc Flash Warning Label attached or "Field Marked" based on the ANSI z535 sign standard.
Electrical inspectors across the country are now enforcing the new labeling requirements set forth in the 2002, 2005 and 2008 National Electric Code (NEC).

ITU has been at the forefront in not only providing "Practical Advice" about how to implement a Safety Training Program, But in providing fast and effective Arc Flash Analysis and Labeling of electrical distribution systems.

“The Arc Flash Analysis was conducted by ITU quickly and professionally. It was just what we asked for and needed. The professionalism at ITU was “Top Notch”, all questions were addressed quickly and accurately. The project was completed to our complete satisfaction!”          Keith Watkins, Oberlin College, OH
