MSHA warns of freeze-thaw hazards in recent safety alert

The Mine Safety and Health Administration (MSHA) recently issued a safety alert cautioning miners about the dangers posed by freeze-thaw cycles. These cycles can cause highwalls to become unstable and create slippery ground conditions, raising the risk of slips, trips, and incidents involving equipment.

Due to freeze-thaw cycle risks, MSHA recommends that miners closely inspect highwalls, banks, slopes, and roadways after major temperature shifts, and check equipment for safe operation. Miners should also:

• Scale hazardous material from a safe location.
• Barricade and post unsafe areas until hazards are corrected.
• Maintain clean catch benches and rockfall areas.
• Update and follow all Ground Control Plan procedures.
