Objective

To understand the required Personal Protective Equipment (PPE) for underground mining operations, including respiratory protection, hearing protection, and protective clothing, ensuring worker safety and regulatory compliance.

Introduction

Underground mining presents unique challenges and hazards that necessitate the use of appropriate PPE. This toolbox talk will cover the essential PPE required for underground mining operations to protect workers from potential hazards and ensure compliance with safety regulations.

Key Points

• Hazard Assessment: Employers are required to assess the workplace to determine if hazards are present, or are likely to be present, which necessitate the use of personal protective equipment (PPE). This assessment should be documented with a written certification that identifies the workplace evaluated, the person certifying the evaluation, the dates of the assessment, and identifies the document as a certification of hazard assessment. [2] [2]
• Respiratory Protection: In underground mining, the air may be contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors. When effective engineering controls are not feasible, appropriate respirators must be used. A written respiratory protection program is required, including procedures for respirator use, maintenance, and fit testing. [6] [6] [6]
• Hearing Protection: Underground mining operations often involve high levels of noise exposure. Hearing protection must be provided and used in areas where noise levels exceed permissible limits. Ear protective devices inserted in the ear shall be fitted or determined individually by competent persons. [6] [1]
• Protective Clothing: Appropriate protective clothing, including coveralls, gloves, and boots, is essential to protect against physical hazards, chemical exposure, and other potential risks in the underground mining environment. The selection of protective clothing should be based on the specific hazards present. [4]
• Head Protection: Hard hats are required to protect against head injuries from falling objects, low clearances, and other overhead hazards. Ensure the hard hat is in good condition and worn properly. [9]

Hazard Identification

• Exposure to harmful dusts, gases, and vapors: Respiratory illnesses, poisoning, asphyxiation (Risk: High)
• High noise levels from machinery and equipment: Hearing loss, tinnitus (Risk: Medium)
• Falling objects and low clearances: Head injuries, fractures (Risk: Medium)
• Chemical exposure from mining materials: Skin irritation, chemical burns, systemic toxicity (Risk: Medium)
• Physical injuries to limbs and body: Cuts, abrasions, fractures (Risk: Medium)

Control Measures

• Use of respirators in areas with hazardous air quality: Ensure proper fit testing, maintenance, and training on respirator use. [5]
• Use of hearing protection in high-noise areas: Provide appropriate earplugs or earmuffs and enforce their use. [3]
• Wearing hard hats at all times: Ensure hard hats are in good condition and worn correctly. [9]
• Use of appropriate protective clothing: Provide coveralls, gloves, and boots suitable for the specific hazards. [4]
• Regular inspection and maintenance of PPE: Ensure PPE is clean, functional, and replaced when damaged. [5]

Personal Protective Equipment (PPE) Requirements

• Respirator: A respirator protects against inhalation of harmful airborne contaminants. Ensure it fits properly and is NIOSH-approved. Inspect before each use and replace filters regularly. [8]
• Hearing Protection (Earplugs or Earmuffs): Hearing protection prevents hearing damage from loud noises. Choose appropriate protection based on noise levels and ensure a proper fit. Clean or replace regularly. [3]
• Hard Hat: A hard hat protects the head from falling objects and impacts. Ensure it fits properly and is in good condition. Replace after any impact. [9]
• Protective Clothing (Coveralls): Coveralls protect the body from physical and chemical hazards. Select appropriate material based on the specific hazards present. Ensure they fit properly and are clean. [7]
• Gloves: Gloves protect hands from cuts, abrasions, and chemical exposure. Choose appropriate material based on the specific hazards. Inspect for damage before each use. [7]
• Boots: Steel-toe boots protect feet from impacts and punctures. Ensure they fit properly and provide adequate support. Inspect for damage regularly. [7]

Group Discussion

Discuss the following questions:

1. What types of respiratory hazards have you encountered in the mine?
2. How do you ensure your hearing protection fits properly?
3. What are the signs that your protective clothing is no longer effective?

Emergency Procedures

1. In case of a fall, immediately assess the injured worker and provide first aid. Contact emergency services for further assistance.
2. In the event of a hazardous gas leak, evacuate the area immediately and notify the supervisor. Use self-contained breathing apparatus if trained.
3. For any injury, report the incident to the supervisor and seek medical attention as needed. Document the incident thoroughly.

Summary

Recap of main points:

• Proper PPE is crucial for protecting against hazards in underground mining.
• Regular inspection and maintenance of PPE are essential.
• Always follow established emergency procedures in case of an incident.

Action Items

Specific actions participants should take:

1. Inspect your PPE before each shift to ensure it is in good condition.
2. Report any damaged or missing PPE to your supervisor immediately.
3. Participate actively in all safety training programs.

Remember: Safety First: Protect Yourself Underground!

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