Blue Diamond's Safety Petition Parade Continues Unabated

Published Date: 2/19/2025

Notice

Summary

Blue Diamond Mining, LLC wants to change some safety rules at their mine to use a different method that keeps miners just as safe. They’ve asked the Mine Safety and Health Administration to approve this change, and everyone has until March 21, 2025, to share their thoughts. This could mean safer or more efficient mining without extra costs or risks.

Analyzed Economic Effects

2 provisions identified: 2 benefits, 0 costs, 0 mixed.

Allow specified unapproved PAPRs underground

Blue Diamond Mining asked MSHA to allow two unapproved Powered Air Purifying Respirators (CleanSpace EX and 3M Versaflo TR-800) to be taken into and used inby the last open crosscut at the Bear Branch 2 mine. If approved, miners would have these PAPRs as alternative respirator options, including for miners with facial hair or those who cannot pass a tight-fit test.

Strict training, inspection, and battery rules

The petition would let the PAPRs be used only if the operator follows many conditions: miners must be trained before use and retrained annually in accordance with 30 CFR 48 (initial and experienced miner training), units must be inspected (including a weekly qualified-person exam with records kept for one year), each unit must have a unique ID, and only specified battery packs/power units meeting UL 1642 or IEC 62133 may be used. Charging of batteries must occur in intake air outby the last open crosscut and only with manufacturer-recommended chargers; batteries must not be disassembled, immersed, exposed to water, or stored/used outside manufacturer temperature limits.
