Location: [LOCATION]

Objective

To educate participants on the safe practices for inspecting, repairing, and using extension cords to prevent electrical hazards and ensure workplace safety.

Introduction

Extension cords are commonly used in various work environments to provide power to tools and equipment. However, improper use or damaged cords can lead to electrical hazards, including shocks, burns, or even fires. Understanding how to properly inspect and repair extension cords is crucial for maintaining a safe workplace.

Presenter Note: Engage the audience by asking if anyone has personal experience with extension cord hazards.

Key Points

• Inspection Before Use: Always visually inspect extension cords for external defects such as loose parts, deformed or missing pins, or damage to the outer jacket or insulation before use on any shift [1].
• Handling and Storage: Handle cords carefully to avoid damage. Do not use cords for raising or lowering equipment, and avoid fastening them with staples or hanging them in a way that could damage the insulation [1].
• Grounding: Ensure that cords used with grounding-type equipment contain an equipment grounding conductor and are not altered in a way that interrupts the grounding connection [1].
• Repair and Testing: Remove damaged cords from service until they are repaired and tested to ensure safety. Conduct tests before first use, after repairs, and at regular intervals [2].
• Proper Use: Use cords only for their intended purpose and ensure they are suitable for the conditions of use and location [3].

Hazard Identification

• Electrical Shock: Damaged cords can expose live wires, leading to electrical shock.
• Fire Hazard: Overloaded or damaged cords can overheat and cause fires.
• Trip Hazard: Improperly placed cords can create tripping hazards in the workplace.

Presenter Note: Encourage participants to share any additional hazards they've encountered.

Control Measures

• Elimination: Use permanent wiring instead of extension cords whenever possible.
• Engineering Controls: Use ground-fault circuit interrupters (GFCIs) to protect against electrical shock [4].
• Administrative Controls: Implement a regular inspection and maintenance program for all extension cords [2].
• PPE: Use appropriate personal protective equipment when handling or repairing cords.

Safe Work Procedures

1. Inspect the cord for damage before use.
2. Ensure the cord is rated for the intended use and environment.
3. Use GFCIs when working in wet or conductive environments.
4. Remove damaged cords from service immediately.
5. Repair and test cords before returning them to service.

Presenter Note: If possible, demonstrate the safe work procedure or use visual aids.

Personal Protective Equipment (PPE) Requirements

• Insulated Gloves: Use when handling cords in wet conditions.
• Safety Glasses: Protect eyes from potential sparks during repairs.
• Non-conductive Footwear: Prevent electrical shock in conductive environments.

Real-World Example or Case Study

A worker was electrocuted when using a damaged extension cord that had exposed wires. The incident could have been prevented with proper inspection and use of a GFCI.

Presenter Note: Ask participants if they can relate this example to their own experiences.

Group Discussion

Discuss the following questions:

1. What are the common causes of extension cord damage?
2. How can we improve our current inspection procedures?
3. What additional safety measures can we implement?

Presenter Note: Encourage active participation and facilitate the discussion.

Emergency Procedures

1. Disconnect power immediately if a cord is damaged.
2. Report the incident to a supervisor.
3. Do not attempt repairs unless qualified.
4. Follow lockout/tagout procedures if necessary.

Questions and Answers

Encourage participants to ask questions and provide answers to common questions related to the topic.

• Q: What should I do if I find a damaged cord?
  A: Remove it from service immediately and report it for repair.
• Q: How often should cords be tested?
  A: Before first use, after repairs, and at intervals not exceeding three months [2].
• Q: Can I use an extension cord in wet conditions?
  A: Only if it is rated for wet conditions and used with a GFCI.

Summary

• Always inspect cords before use.
• Handle and store cords properly to prevent damage.
• Use GFCIs to protect against electrical shock.
• Remove and repair damaged cords immediately.

Action Items

1. Review and update the extension cord inspection checklist.
2. Schedule regular training on electrical safety.
3. Implement a GFCI testing program.
