NAICS 22 · Utilities

High-voltage work rules, arc flash, and the standards that keep linemen alive.

Electric power generation, T&D, and water/wastewater utilities operate under some of the most specific safety standards in the code. Cairn maps applicable rules to your work types and surfaces the directives that govern minimum approach distance, FR/AR clothing, and switching procedures.

What we hear from Utilities teams

The compliance questions that won't go away.

Cairn is built around the compliance questions that keep safety directors up at night.

  • Minimum approach distance calculation and crew briefing
  • FR/AR clothing program and arc-flash incident-energy analysis
  • Switching and tagging procedures across IOU and muni operations
  • Confined-space entry into vaults, manholes, and digesters
  • Storm-restoration mutual-aid crew qualifications
