Coal Mine Dust Sampling Device Approval
30 CFR Part 74, including Subparts C and D
Part 74 establishes design, performance, testing and approval requirements for coal mine dust sampling devices. Continuous personal dust monitors provide within-shift and end-of-shift measurements, while other sampler units follow a distinct technical pathway. The approval process involves MSHA and NIOSH. An approved instrument supports exposure measurement; it does not by itself establish that a mine's dust-control program or sampling practice complies with all applicable rules.
