If you read the preamble and supporting material, OSHA went to great lengths to explain what “reasonable” meant. (By the way, the old regulation required pretty much the same thing.)Ĭompanies covered by these regulations were required by January 1, 2015, to assess the workplace to identify employees exposed to the hazard of electric arcs and make a “reasonable” estimate of incident energy to which their employees may be exposed. This requirement was effective immediately upon release, although OSHA stated that the existing requirements in 1910.269 would be acceptable until April 1, 2015. One of the new requirements-1910.269(l)(8)(iii)-is that employers must ensure workers who are exposed to an arc flash hazard do not wear clothing that could melt into their skin if they are exposed to an electrical arc. This article looks at the new requirements for protecting workers from the arc flash hazard. Users of the 1910.269 regulation will find mostly minor changes, except for portions covering information transfer, protecting employees from arc flash hazards, and fall protection. ![]() ![]() Changes made to 1910.269 apply to 1926 Subpart V and vice versa. However, OSHA determined that the hazards and risks covered by the two regulations were very similar, so consistency was needed between them to reduce confusion and simplify their use.ġ910.269 covers electric power generation, transmission, and distribution, while 1926 Subpart V covers construction activities on overhead power lines. There used to be significant differences between OSHA’s 1910.2 Subpart V regulations. ![]()
