Comply with MSHA Regulations with BMair

Mining is demanding, dusty, and high-risk. MSHA, the Mine Safety and Health Administration, is the U.S. authority overseeing safety in the sector, and that includes the air quality inside machine cabins. But what does that mean in practice? And how can you ensure your machines meet these standards?

Stay Safe. Stay Compliant.

Everyone in the mining industry knows MSHA, and knows that compliance isn’t optional. But in reality, that’s easier said than done. Dust, fumes, and gases infiltrate cabins, sensors require calibration, and logbooks pile up.

That’s why BMair developed the Protector: a complete protective ventilation system that actively monitors cabin air quality and automatically meets MSHA requirements. No guesswork, no paperwork, just the certainty that your machines and operators are protected.

Let’s look at which MSHA rules apply to air quality and cabin safety, and how BMair ensures you stay compliant at all times.

Core MSHA Requirements

1

Dust Control

• Crystalline silica: max. 50 µg/m³
• Respirable dust (PM10 and smaller): max. 2 mg/m³
• Cabins must be equipped with engineering controls such as HEPA filtration, fresh air intake, positive pressure, and exhaust for contaminated air

2

Monitoring and Alarming

• Cabins must have real-time monitoring of: air pressure, CO₂/gases, system status, door movements, and filter condition
• Exceedances must trigger visual and audible alarms
• All data must be recorded and logged for audits

3

Inspections & Maintenance Logs

• Daily pre-shift inspections: air intake, filters, alarm systems
• Weekly documentation of checks is mandatory
• Inspectors review: filter systems, logbooks, alarm history, and air quality measurements

How BMair Helps You Meet MSHA Regulations

MSHA sets clear requirements. BMair provides a complete solution that covers every aspect of the standard. Our protective ventilation systems are specifically designed for heavy industrial and mining environments, forming a complete, certified protective ventilation system.

Silica? No Risk.

Our systems eliminate fine dust from cabin air. In measured applications with BMair systems, dust levels remain at 0.005 µg/m³, well below the ≤ 50 µg/m³ MSHA limit. In addition, our in-cabin Airhub continuously measures particulate matter and automatically flushes the air if levels rise too high.

Continuous Overpressure in Cabin

The BMair Protector maintains a stable overpressure of 100 Pa at all times. This keeps contaminants and harmful fumes out while ensuring a comfortable working environment for the operator.

Full Real-Time Monitoring

The Protector continuously monitors all critical parameters. Receive automatic notifications for filter status, airflow, system pressure, and CO₂ levels, all visible through our online portal. Visual and audible alerts keep both operators and maintenance teams continuously informed.

ISO-Certified Filters

All filters are ISO 29463-certified, clearly labeled, individually serialized, and fully traceable. You always know you’re working with certified components.

Always Proof of Compliance

With the BMair Protector, you’re always demonstrably compliant with MSHA regulations. With a single click, you can display digital reports and system history, automatically stored in BMair Connect, ensuring transparent evidence of compliance at any time.
