Objective

To ensure the safe use, inspection, and handling of extension cords in the workplace to prevent electrical hazards and comply with OSHA regulations.

Introduction

Extension cords are commonly used to power tools and equipment, but they can pose significant electrical and tripping hazards if not properly inspected, used, and maintained. This toolbox talk will cover key safety considerations for extension cords in the workplace. [1] [2]

Key Points

• Regular Inspection: Inspect extension cords before each use for any signs of damage, such as cuts, fraying, exposed wires, or missing ground prongs. Remove damaged cords from service immediately. [1] [1] [2] [3]
• Proper Grounding: Ensure that extension cords are 3-wire type to provide grounding for tools and equipment. Never remove the grounding prong from a plug. [1] [7]
• Avoid Overloading: Do not overload circuits by plugging multiple extension cords or too many tools into one outlet. Use the correct gauge of extension cord for the intended electrical current. [4] [5] [6]
• Safe Usage: Do not run cords through doorways, ceilings, walls, or windows where they can be damaged. Protect cords from traffic and physical damage by using cable protectors. [3] [3]
• GFCI Protection: Use Ground Fault Circuit Interrupters (GFCIs) in wet or damp locations to protect against electrical faults. Test GFCIs regularly to ensure they are functioning correctly. [2] [5] [7]
• Proper Storage: Coil cords properly to prevent pinching and damage. Disconnect cords at the plug, not by pulling on the cord itself. [3] [3]

Hazard Identification

• Damaged or Frayed Cords: Electric shock, burns, fire. [1]
• Missing Ground Prongs: Electrical shock, equipment damage. [2]
• Overloaded Circuits: Overheating, fire, equipment failure. [4]
• Wet Conditions: Electric shock, electrocution. [1]
• Improper Use: Tripping hazards, cord damage, electrical shock. [2]

Control Measures

• Regular Visual Inspections: Inspect cords for damage before each use. Remove damaged cords from service. [1] [1]
• Use GFCI Protection: Utilize Ground Fault Circuit Interrupters (GFCIs), especially in wet or damp locations. Test regularly. [2]
• Proper Cord Management: Avoid running cords through doorways or in high-traffic areas. Use cable protectors. [2]
• Correct Cord Selection: Use the appropriate gauge and type of cord for the intended use. [6]
• Grounding: Ensure all cords have a functional grounding prong and are plugged into grounded outlets. [1]
• Avoid Overloading: Do not overload circuits or use multiple cords connected together. [2]

Personal Protective Equipment (PPE) Requirements

• Safety Glasses: Wear safety glasses to protect eyes from potential electrical arcs or flashes.
• Insulated Gloves: Use insulated gloves when handling extension cords in wet conditions or when there is a risk of electrical contact.
• Appropriate Footwear: Wear appropriate footwear to provide insulation from electrical hazards.

Real-World Example or Case Study

Bernard was using a coring machine powered by two extension cords, one of which was missing its grounding prong. He received a shock and suffered an electrical burn. This incident highlights the importance of inspecting cords and ensuring proper grounding. [2]

Group Discussion

Discuss the following questions:

1. What are the most common causes of extension cord damage on our site?
2. How can we improve our inspection process for extension cords?
3. What steps can we take to prevent tripping hazards related to extension cords?

Emergency Procedures

1. 1. Disconnect the power source immediately if safe to do so.
2. 2. If someone is in contact with a live wire, do not touch them. Use a non-conductive object to separate them from the source.
3. 3. Call for emergency medical assistance (911).

Questions and Answers

Do you have any questions about extension cord safety?

• Q: What should I do if I find a damaged extension cord?

A: Remove it from service immediately and report it to your supervisor.

• Q: Can I repair a damaged extension cord with electrical tape?

A: No, damaged cords should never be repaired with tape. They must be removed from service. [3]

Summary

Recap of main points:

• Inspect extension cords before each use. [1]
• Ensure proper grounding and GFCI protection. [2]
• Avoid overloading circuits and protect cords from damage. [4]
• Use extension cords safely and store them properly. [3]

Action Items

Specific actions participants should take:

1. Commit to inspecting extension cords before each use.
2. Report any damaged cords immediately.
3. Follow safe practices for cord usage and storage.

Remember: Safety First: Inspect, Protect, Respect Extension Cords.

Report all hazards, near-misses, and incidents to your supervisor immediately.
