In June 2024, the Mine Safety and Health Administration (MSHA) published its final ruling for Respirable Crystalline Silica (RCS) dust exposure.

“The permissible exposure limit (PEL) for respirable crystalline silica from 100 micrograms (µg) to 50 µg per cubic meter of air (µg/m3) over a full-shift exposure, calculated as an 8-hour time-weighted average (TWA) for all mines.”

This new ruling requires compliance to lowered limits of miners’ RCS exposure and provisions for improvement in respiratory protection.

Here are some frequently asked questions about Respirable Crystalline Silica dust:

1. When does this new mandate go into effect?

• • By April 14, 2025, for coal mining operations
  • By April 8, 2026, for MNM (metal and nonmetal) mining operations

2. What are the dangers of Silica Dust?
   • Crystalline Silica Dust can possibly lead to numerous health problems such as lung cancer, pulmonary fibrosis, COPD, and more. For more information around health concerns, read more from the American Lung Association: https://www.lung.org/blog/silica-dust-lung-diseases

3. How do I know if we’re exceeding the exposure limit?
