Objective

To understand electrical hazards and implement preventive measures to ensure safety.

Introduction

Electricity is a powerful and essential part of our lives, but it can also be dangerous if not handled properly. This toolbox talk will cover basic electrical safety precautions and hazard prevention measures to protect ourselves and our colleagues from electrical injuries.

Key Points

• Minimum Approach Distances (MAD): Maintain a safe distance from electrical lines and apparatus. This machine is not insulated and does not provide protection from contact or proximity to electrical current. [13] [14]
• Assume Energized Parts: Always assume all electrical parts and wiring are energized unless known otherwise. Never maneuver machines or personnel inside the prohibited zone (MAD). [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [16] [17] [18]
• Insulating Barriers: The minimum approach distance may be reduced if insulating barriers are installed to prevent contact, and the barriers are rated for the voltage of the line being guarded. These barriers shall not be part of (or attached to) the machine. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [16] [17] [18]
• Weather Conditions: It is not recommended to use the machine during lightning. To prevent injury or machine damage if lightning occurs during operation, lower the boom and shut down the machine in a safe and secure location. [13] [14]

Hazard Identification

Identifying potential electrical hazards is crucial for preventing accidents and injuries. Here are some common hazards to be aware of:

• Contact with energized sources: Electrocution, severe burns, cardiac arrest. (Risk: High)
• Damaged Cords and Equipment: Electrical shock, burns, fire. (Risk: Medium)
• Working in wet conditions: Increased risk of electric shock. (Risk: Medium)

Control Measures

• Use Ground Fault Circuit Interrupters (GFCIs): GFCIs protect against electrical shock by monitoring the current and quickly shutting off the power if a ground fault is detected.
• Regularly inspect electrical cords and equipment: Check for damage such as frayed cords, cracked insulation, and broken connectors. Remove any damaged equipment from service immediately.
• Maintain Minimum Approach Distances (MAD): Always maintain the required clearance from overhead power lines and other energized sources. Refer to Table 1-1 for specific distances. [15]

Personal Protective Equipment (PPE) Requirements

• Insulated Gloves: Wear insulated gloves when working with or near electrical equipment. Inspect gloves for damage before each use.
• Safety Footwear: Wear safety footwear with non-conductive soles to provide insulation from ground.
  • Ensure footwear is in good condition.
  • Replace if soles are worn or damaged.

Emergency Procedures

1. Immediately call for emergency medical assistance.
2. Do not touch the person if they are still in contact with the electrical source.
3. Shut off the power source if it is safe to do so.

Questions and Answers

• Q: What is the first thing you should do if you see a damaged power cord?

A: Remove it from service immediately and report it.

• Q: What should you do if someone is being electrocuted?

A: Call for help immediately and turn off the power source if safe.

Summary

Recap of main points:

• Always assume electrical parts are energized.
• Maintain safe distances from electrical lines.
• Use appropriate PPE and inspect equipment regularly.

Remember: Safety First: Respect Electricity!

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