OSHA compliance for utilities: high-voltage rules and arc flash.
OSHA compliance for utilities runs on 29 CFR 1910.269 — some of the most specific safety standards in the code. Electric power generation, T&D, and water/wastewater utilities (NAICS 22) operate under high-voltage work rules where Cairn maps the applicable sections to your work types and surfaces the directives that govern minimum approach distance, arc flash, FR/AR clothing, and switching procedures.

Utilities OSHA compliance, answered
What does OSHA 1910.269 require for utility line work?
29 CFR 1910.269 governs electric power generation, transmission, and distribution — covering minimum approach distance, arc-flash incident-energy analysis, FR/AR clothing, and switching and tagging. Cairn maps the applicable sections to your work type and returns the cited requirement with the interpretation library behind it.
What are OSHA's arc flash and FR clothing requirements?
Under 1910.269, employers must assess arc-flash exposure (incident energy) and provide FR/AR clothing rated for the hazard. Cairn surfaces the current tables, the underlying calculations, and how the agency has applied them in enforcement.
How is minimum approach distance determined for high-voltage work?
Minimum approach distance comes from the voltage-based tables in 29 CFR 1910.269 and its appendices, adjusted for transient overvoltage. Cairn returns the controlling table and the directives behind it so crew briefings cite the right figure.
