Permit Dräger X‑plore 8700 PAPRs

Signal Peak Energy, LLC has asked MSHA to modify 30 CFR 75.507-1(a) so the Dräger X‑plore 8700 powered air purifying respirators (PAPRs) may be used in return air outby the last open crosscut at Bull Mountains Mine No. 1 (MSHA ID 24-01950). The company says the Dräger units offer improved performance, battery life, durability, and air volume and that the alternative method will guarantee no less protection than the current mandatory standard. Comments on this petition (Docket M-2025-012-C) are due by April 3, 2025.

Required safety conditions for new PAPRs

The petition proposes conditions for using Dräger X‑plore 8700 PAPRs: batteries may be charged only in intake air (surface or underground) and not within 150 feet of a worked-out area; battery inspections and replacements must occur in intake air; only specified Li‑Ion battery packs (10.8 V, 6400 mAh P/N R59575 or 10.8 V, 3350 mAh P/N R59595) with chargers Um = 18 V DC may be used; miners must be trained and units checked for physical damage before each use; units must not be used if methane is at or above 1%, and equipment must be de-energized and removed if methane exceeds that threshold. The petition also requires training records to be kept and provided upon request.
