Extension cords and temporary power cables are lifelines on a jobsite — but they’re also a major source of electrical hazards when damaged or misused.
Why It Matters:
Damaged cords and unprotected connections are among the top electrical violations cited by OSHA. Cuts, frays, or crushed wires expose workers to shock, arc flash, or even fires — especially in wet or high-traffic areas.
Key Points:
- Inspect all cords daily for cuts, nicks, exposed wires, or missing grounding prongs.
- Use only heavy-duty, outdoor-rated cords approved for jobsite use (12-gauge or thicker for high load).
- Protect cords from traffic:
- Never run cords across drive lanes or where they’ll be crushed by equipment.
- Use cord ramps or hang cords overhead when possible.
- Never repair a cord with electrical tape or make homemade splices — replace or tag out.
- Keep connections dry and elevated. Use weatherproof covers and cable protectors for outdoor use.
- Label circuits and keep loads balanced when using multiple tools or generators.
✅ Your cords carry power — and risk. Treat them like safety gear.
Ask the Crew:
- Are any cords frayed, missing prongs, or taped up?
- Do we have a plan to keep cords out of walkways and work areas?
- Are our temporary circuits properly labeled and protected?
