Presenter: [PRESENTER NAME]
Location: [LOCATION]

Objective

The objective of this toolbox talk is to educate participants on the critical safety measures required for working in underground mines, focusing on hazard identification, control measures, and emergency procedures.

Introduction

Working in underground mines presents unique safety challenges due to confined spaces, potential for hazardous gases, and the complexity of evacuation routes. Ensuring safety in these environments is crucial to prevent accidents and ensure the well-being of all workers.

Presenter Note: Engage the audience by asking if anyone has personal experience related to underground mine safety.

Key Points

• Hazardous Gases: Continuous monitoring of flammable and combustible gases is essential to prevent explosions and ensure worker safety .
• Fire Prevention: Implementing fire detection and suppression systems is critical to manage fire risks in underground mines .
• Evacuation Routes: Clearly marked and strategically placed escape ways and refuge stations are vital for safe evacuation during emergencies .
• Proximity Detection Systems: These systems help prevent accidents by stopping equipment before it contacts a worker .
• Regular Inspections: Conducting regular inspections of underground work areas and equipment ensures ongoing safety and compliance .

Hazard Identification

Common hazards in underground mines include:

• Flammable Gases: Can lead to explosions if not properly monitored and controlled .
• Fire Hazards: Ignition sources and combustible materials can cause fires if not managed properly .
• Structural Failures: Unstable mine walls or ceilings can collapse, posing a risk to workers .

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

Control Measures

Discuss the hierarchy of controls:

• Engineering Controls: Install gas detection systems and fire suppression systems .
• Administrative Controls: Regularly update and review work shift reports and conduct mock evacuation exercises .
• Personal Protective Equipment (PPE): Ensure workers have access to self-rescue equipment and are trained in its use .

Safe Work Procedures

1. Conduct a pre-shift inspection of the work area.
2. Ensure all gas detection and fire suppression systems are operational.
3. Review emergency evacuation routes and procedures with the team.
4. Monitor gas levels continuously and respond to alarms immediately.
5. Conduct regular safety drills and training sessions.

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

Personal Protective Equipment (PPE) Requirements

• Self-Rescue Equipment: Must be carried by all workers underground and used during emergencies .
• High-Visibility Apparel: To ensure workers are visible to equipment operators .
• Respiratory Protection: For areas with potential gas exposure .

Real-World Example or Case Study

Discuss a past incident where a lack of proper gas monitoring led to an explosion in an underground mine. Highlight the importance of continuous monitoring and immediate response to alarms.

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

Group Discussion

Discuss the following questions:

1. What are the most common hazards you've encountered in underground mines?
2. How do you ensure your safety and the safety of your coworkers?
3. What improvements can be made to current safety procedures?

Presenter Note: Encourage active participation and facilitate the discussion.

Emergency Procedures

Outline the steps to take in case of an emergency:

1. Activate the emergency warning system.
2. Follow the marked escape routes to the nearest exit or refuge station.
3. Use self-rescue equipment if necessary.
4. Report to the designated assembly area for a headcount.

Questions and Answers

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

• Q: What should you do if you hear a gas alarm?
  A: Immediately back the equipment out of the working face and turn off the power .
• Q: How often should evacuation drills be conducted?
  A: At least annually, with a report made of the exercise .
• Q: What is the role of proximity detection systems?
  A: To stop equipment before it contacts a worker .

Summary

Recap the main points covered in the toolbox talk:

• Importance of gas monitoring and fire prevention.
• Need for clear evacuation routes and regular drills.
• Role of PPE in ensuring worker safety.
• Continuous improvement of safety procedures.

Action Items

List specific actions participants should take following this toolbox talk:

1. Review and familiarize yourself with the emergency evacuation routes.
2. Ensure your self-rescue equipment is in good condition and accessible.
3. Participate in regular safety drills and training sessions.
