GFCIs don’t last forever — and if they fail silently, your protection is gone.
Why It Matters:
Just like smoke alarms, GFCIs need to be tested regularly. Dust, moisture, age, or internal damage can cause a GFCI to stop working without warning. If you’re relying on a faulty unit, you have zero protection against deadly ground faults.
Key Points:
- OSHA recommends testing GFCIs at least once a month, or before use on jobsites with wet or high-risk conditions.
- Use the built-in “TEST” and “RESET” buttons: Press TEST (the power should cut), then RESET (power should restore).
- If the GFCI doesn’t trip or reset properly, tag it out and replace it immediately.
- Keep a regular log or calendar reminder for GFCI inspections across all work zones and trailers.
- Temporary power systems are especially vulnerable — never assume a GFCI is working just because it’s plugged in.
✅ Monthly tests = constant protection.
Ask the Crew:
- When was the last time we tested our GFCIs?
- Do we have a routine for checking them on this site?
