Toolbox Talk:

Know the Signs of GFCI Failure on the Jobsite

June 22, 2025

GFCIs can fail quietly or obviously — either way, you must catch it before someone gets shocked.

Why It Matters:

GFCIs are your first defense against electrocution. But like any piece of equipment, they can wear out, get damaged, or malfunction. If you don’t recognize when a GFCI isn’t working right, it creates a false sense of security and puts lives at risk — especially when working with water, wet tools, or metal surfaces.

Key Points:

  • Buzzing, clicking, or overheating are signs of internal GFCI problems.
  • If you press TEST and nothing happens, or the outlet still has power after tripping, the unit is faulty.
  • Tools plugged into a bad GFCI might spark, overheat, or run inconsistently.
  • Physical damage, like cracked outlets or broken reset buttons, means immediate removal from service.
  • Report and replace any suspect GFCI immediately — do not “work around it” or tape over it.

✅ A failed GFCI is more dangerous than none at all — because it fools you into thinking you’re protected.

Ask the Crew:

  • Have we seen any suspicious outlets this week?
  • Do we know how to test and recognize a failing GFCI?
