Extension cords take a beating on job sites — but they’re not built to handle crushing, cutting, or constant exposure to moisture.
Why It Matters: Damaged extension cords are one of the most common causes of electrical shock and arc flash incidents in construction. Misusing or overloading them can also start fires or damage equipment.
Key Points:
- Inspect cords daily for cuts, exposed wires, or crushed insulation.
- Never run cords through doorways, windows, or pinch points.
- Avoid daisy-chaining multiple cords or using undersized cables for heavy-duty tools.
- Make sure GFCI protection is used with all extension cords, especially in wet or outdoor areas.
- Cords must be rated for job site use (check for “Outdoor” or “Heavy Duty” labeling).
✅ If your cord is cracked, pinched, or overloaded — it’s not job-ready.
Ask the Crew:
- Are all cords in use today rated for the environment and load?
- Do we have a routine for removing damaged cords from service?
