Know which electrical rules apply
Learning objective: Recognize the course scope and when to stop for electrical help.
This course explains federal OSHA electrical safety work practices for general-industry premises wiring and equipment under 1910.331 through 1910.335. It addresses people who use equipment as well as people assigned electrical work. A worker can be exposed without being an electrician: moving a ladder, cleaning near an open panel or using a damaged cord can create a path for current.
Electric shock can injure or kill. An electric arc can cause severe burns, fire and flying debris without direct hand contact with a conductor. Indirect contact through a tool, pipe, ladder or equipment frame also matters. The controls must match the actual hazard, voltage and work conditions.
The employer determines the applicable rules from the work and installation. Construction electrical rules are in 1926 Subpart K and related provisions; this general-industry course does not replace them. Qualified work on or directly associated with power generation, transmission and distribution installations generally follows 1910.269. Communications, vehicle and railway installations have additional scope distinctions in 1910.331(c).
The exclusions for qualified work do not simply exclude everyone nearby. Section 1910.331(b) covers unqualified people working on, near or with the listed installations, and qualified people nearby whose work is not on or directly associated with them. Ask the employer which rule governs your actual assignment.
Keep covers and guards in place, observe warnings and report damage. If you cannot identify a safe method or your assigned limits, stop and contact the designated supervisor or electrical specialist. Do not open equipment to investigate simply because a course mentioned a hazard.
