DID YOU KNOW?
The first high-sensitivity GFCI (ground fault circuit interrupter) was invented in 1961, helping prevent electrocution by detecting tiny leakage currents. [3] But it only works when your system is properly grounded.
KNOW THE RISK
- Grounding a tool or electrical system means intentionally creating a low-resistance path for electricity to flow safely to the earth. This helps redirect stray voltage in the event of a fault. [1]
- Proper electrical grounding can help prevent electric shocks, fires, and equipment damage. [1]
- If the grounding path is broken at any point, the circuit becomes hazardous, and a fault current could flow through a person instead. [2]
MITIGATE THE RISK
1. Use Grounded Tools and Appliances
- All electric tools or appliances should either be double insulated or have a grounded three-prong plug. Never use a tool with a missing or damaged plug. [2]
2. Never Remove the Third Prong
- The third (round) prong provides the ground connection. Cutting it off disables a key safety feature and creates serious electrocution risk. [2]
3. Always Use a GFCI in Wet or Damp Areas
- Ground fault circuit interrupters (GFCIs) shut off power in milliseconds if a ground fault is detected. These are critical in bathrooms, kitchens, outdoor areas, and job sites. [2]
ELECTRICAL SAFETY REMINDER
You can’t see electricity — but you can protect yourself from it. Proper grounding makes the invisible threat of electrical shock preventable. Inspect your cords, plugs, and outlets regularly, and never ignore signs of electrical wear or damage.
