MSHA Proposes Revised Rule for Miner Silica Dust Protection

The U.S. Department of Labor's Mine Safety and Health Administration (MSHA) has introduced an updated proposed rule to enhance protections for miners against crystalline silica dust exposure. This proposal amends a 2024 rule, incorporating practical, risk-based improvements across areas like compliance, exposure monitoring, medical surveillance, recordkeeping, and respiratory protection. The aim is to safeguard miner health by reducing hazards from silica dust.
