Mine safety and equipment approval

Mine Safety and Health Administration

MSHA administers mine safety requirements and approval pathways for specified mining equipment. Approval conditions depend on the equipment category and intended mining environment.

Read the source in its own scope

Mine Safety and Health Administration is represented in this collection through the specific publications listed below. Begin with the product, activity and responsible party identified by the source. A reference to an agency does not establish that every product in an industry follows the same pathway. Scope, definitions, exceptions and the status of an adopted technical document can change the conclusion.

Connect the publication to the product decision

Use the original publication to establish the requirement, then connect it to the actual model, configuration, process or transaction. Keep source dates separate from effective and compliance dates. Where several agencies are relevant, preserve a distinct conclusion for each framework. A test report, registration, approval, certification and voluntary program claim should be assessed for the precise object and conditions they cover.

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.

Electrical Equipment Approval for Gassy Mines

30 CFR Part 18; independent laboratory procedures at 30 CFR Part 6

MSHA's electrical approval framework addresses ignition hazards in gassy mining environments. It distinguishes approval of complete machines or accessories from certification of components. Current Part 18 includes an alternative route using specified incorporated consensus standards, subject to the stated protection requirements. A general explosion-protection certificate or overseas marking does not automatically establish that a machine has the required MSHA approval.
