What HR and Safety Teams Need to Know About MSHA Part 62

Mining operations face unique hearing conservation challenges. The Mine Safety and Health Administration (MSHA) has established Part 62 regulations to protect miners from occupational hearing loss. Understanding these requirements helps HR and safety teams create effective hearing conservation programs for their mining workforce.

MSHA vs. OSHA: Key Differences

Both MSHA and OSHA set their action level at 85 dB(A) over an 8-hour time-weighted average, but MSHA's enforcement and implementation requirements have specific nuances for mining operations. MSHA regulations apply to all mining activities, including surface and underground operations, while OSHA covers general industry.

MSHA's Part 62 includes specific provisions for:

• Mobile equipment operators who move between different noise environments
• Underground mining conditions where noise levels can vary significantly
• Surface mining operations with heavy machinery

Enrollment Requirements

When miners are exposed to noise at or above the 85 dB(A) action level, MSHA requires immediate enrollment in a hearing conservation program (HCP). This enrollment must happen regardless of whether the exposure is expected to be temporary or permanent.

Mining companies must provide training within 30 days of enrollment. This training covers hearing anatomy, the effects of noise exposure, proper use of hearing protection, and the miner's role in the hearing conservation program.

Testing and Monitoring

Miners in the HCP must receive:

• A baseline audiogram within 6 months of enrollment
• Annual audiometric evaluations
• Follow-up testing if hearing changes are detected

The baseline audiogram must be preceded by at least 14 hours without occupational noise exposure, similar to OSHA requirements. This can be challenging in mining operations with around-the-clock schedules, but proper planning can accommodate this requirement.

Hearing Protection Requirements

MSHA requires mining companies to provide hearing protectors at no cost to miners. The protection must be appropriate for the specific noise environment and properly fitted. Companies must also ensure miners receive training on:

• Proper insertion and removal techniques
• Care and maintenance of hearing protectors
• Recognition of damaged or worn-out protection

Record Keeping for Mining Operations

Mining companies must maintain detailed records including:

• Noise exposure assessments for each work area
• Individual audiometric test results
• Training records and dates
• Hearing protector distribution logs

These records help demonstrate compliance during MSHA inspections and provide valuable data for improving hearing conservation efforts.

Special Considerations for Mining

Mining environments present unique challenges for hearing conservation:

• Variable noise levels as miners move between work areas
• Communication needs in high-noise environments
• Integration with other safety equipment like hard hats and respirators
• Harsh conditions that can affect hearing protector performance

Why Choose OCC Hearing for Mining Operations

Mining environments present unique challenges that require specialized expertise. Unlike high-volume testing services that often use technicians, we exclusively send licensed audiologists or trained hearing instrument specialists to your mine sites. This professional approach ensures accurate testing results and expert guidance for your specific mining environment.

Our services are fully compliant with both OSHA (29 CFR 1910.95) and MSHA (30 CFR Part 62) regulations. We understand the distinct requirements for mining operations and ensure all protocols are followed precisely. Our flexible scheduling accommodates mining operations' unique shift patterns and on-site constraints.

Beyond compliance, we provide ongoing hearing wellness resources and employee benefits that support your miners' long-term hearing health. Our concierge-level service includes post-screening support and customized solutions for your mining operation's specific needs.

Program Administration

Managing a hearing conservation program in mining requires coordination between multiple departments. Safety teams need to conduct noise assessments, HR departments handle training and record keeping, and management must ensure adequate resources and support.

Many mining companies find that partnering with specialized hearing conservation providers helps ensure compliance while reducing administrative burden. This approach allows internal teams to focus on core mining operations while maintaining worker safety.

Taking Action

Protecting your miners' hearing requires a comprehensive approach that goes beyond just meeting minimum requirements. A well-designed hearing conservation program can reduce workers' compensation claims, improve productivity, and demonstrate your commitment to worker safety.

We work with mining operations to develop and implement hearing conservation programs that meet MSHA Part 62 requirements. Reach out to our team to learn more about our industrial testing services and how we can support your mining operation's hearing conservation needs.
