Using GFCIs and Inspecting Extension Cords

Electrocution | OSHA Fatal Four

The Problem

Extension cords and temporary wiring are common tools on job sites, but they also pose serious electrical hazards. Faulty cords, damaged insulation, or the absence of a Ground Fault Circuit Interrupter (GFCI) can result in electric shock, fires, or even fatalities. Today, we’ll discuss how to inspect extension cords and use GFCIs properly to protect ourselves and our coworkers.

Identify the Hazards

  • Electric Shock: Caused by damaged cords, frayed insulation, or improperly grounded circuits.
  • Overloading: Using cords not rated for the load can cause overheating and fires.
  • Moisture Exposure: Extension cords used in wet conditions increase the risk of shock without proper protection.‍
  • Lack of GFCI Protection: Without GFCIs, there’s no safeguard against ground faults, which can occur when electricity escapes its intended path.

Safety Practices and Preventative Measures

To mitigate these hazards, always follow these steps:

  1. Inspect Extension Cords Before Use:

    • Look for cuts, cracks, or frayed insulation.
    • Check plugs and prongs for damage or looseness.
    • Ensure there are no exposed wires.
  2. Use GFCIs on All Circuits:

    • Connect all extension cords to outlets equipped with GFCIs.
    • Test GFCIs before use by pressing the “Test” button to ensure they trip, and then the “Reset” button to restore power.
  3. Select the Right Cord:

    • Use cords rated for the electrical load of your equipment.
    • Ensure cords are UL-listed and designed for outdoor use when used outside.
  4. Protect Cords From Damage:

    • Do not run cords through doorways, windows, or sharp edges.
    • Avoid placing cords in high-traffic areas where they may be stepped on or driven over.
    • Use cord covers or mats to protect them if necessary.
  5. Avoid Wet Conditions:

    • Never use extension cords or electrical equipment in wet areas unless they are specifically rated for such conditions.
    • Use proper PPE, such as rubber-soled boots and insulated gloves, in damp environments.
  6. Regular Maintenance and Reporting:

    • Remove damaged cords from service immediately.
    • Tag defective cords and report them to your supervisor for repair or replacement.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

E.g. A worker on a construction site once plugged a damaged extension cord into an outlet without a GFCI. The cord had a cut in the insulation, and when it came into contact with a puddle, the worker suffered a severe electric shock. This incident could have been prevented by using a GFCI and inspecting the cord before use.

Employee Responsibilities

  • Inspect all extension cords and GFCIs before each use.
  • Report damaged cords or defective GFCIs to your supervisor immediately.
  • Use only cords rated for the job and avoid makeshift repairs.
  • Follow OSHA requirements for using GFCIs in temporary wiring systems.

Employer Responsibilities

  • Provide GFCIs and extension cords that meet OSHA standards.
  • Ensure all temporary wiring is inspected and maintained regularly.
  • Replace damaged cords or defective GFCIs promptly.
  • Train employees on the proper use and inspection of electrical equipment.

Discussion & Questions

  • "What are some common issues you’ve encountered with extension cords or GFCIs on our site?"
  • "How do you ensure cords and GFCIs are safe to use?"
  • "Does anyone have an example of a near-miss or incident involving these tools?"

(Allow employees to share concerns or experiences and address their questions.)

Commitment/Action Plan

Starting today, let’s commit to inspecting every extension cord and GFCI before use. If you find any damage or defects, report them immediately. Let’s work together to ensure a safe and hazard-free workplace.

Wrap-Up

Electrical hazards are preventable when we follow proper safety protocols. By using GFCIs and inspecting extension cords, we can avoid unnecessary injuries and maintain a safe environment for everyone. Thank you for your attention and your commitment to safety.

Standards Overview

  • OSHA Standard 1926.404(b): Requires the use of GFCIs for all 120-volt, single-phase, 15- and 20-amp receptacles on construction sites.
  • Temporary Wiring Safety: OSHA mandates regular inspection and proper grounding of all extension cords and temporary power sources.

These standards are in place to prevent injuries and ensure electrical safety.
