Exposure Monitoring & Sampling
- Are representative respirable crystalline silica exposure samples collected for each affected occupation? *
- Is the permissible exposure limit of 50 µg/m³ (8-hour TWA) used as the compliance benchmark? *
- When a sample meets or exceeds the action level of 25 µg/m³, is follow-up (periodic) monitoring conducted? *
- Are miners promptly notified of their sampling results? *
- Record the most recent 8-hour TWA silica result (µg/m³). *
Engineering & Administrative Controls
- Are engineering controls (water sprays, dust collection, enclosed cabs, ventilation) used to reduce silica and respirable dust? *
- Are controls maintained and their effectiveness verified where exposures exceed the PEL? *
- Is a written exposure control plan in place identifying tasks and corresponding controls? *
Respiratory Protection
- Where controls cannot reduce exposure to the PEL, are appropriate NIOSH-approved respirators provided? *
- Are affected miners fit-tested and included in a written respiratory protection program? *
- Are respirator cartridges/filters appropriate for respirable dust and maintained? *
Medical Surveillance & Records
- Are periodic medical examinations (including chest X-ray and spirometry) offered to exposed miners at no cost? *
- Are exposure monitoring and medical surveillance records retained for the required duration? *
- Are corrective actions documented when overexposures are identified? *
