The Mine Safety and Health Administration (MSHA) proposes to revise 30 CFR part 18 that sets out the testing, evaluation, and approval requirements for electric motor-driven equipment and accessories intended for use in gassy mines. Under this proposal, MSHA would accept voluntary consensus standards that are suitable for all gassy mining environments and that provide protection against fire or explosion dangers to replace applicable requirements in 30 CFR part 18. This proposed rulemaking is intended to promote the use of innovative and advanced technologies that lead to improvements in mine safety and health and to improve the efficiency and effectiveness of MSHA’s product approval process. This rulemaking was initiated by stakeholders’ recommendations, which MSHA received in response to the Agency’s request for stakeholders’ assistance in identifying regulations for review. Specifically, MSHA received recommendations to reduce the government-specific standards and to use voluntary consensus standards.
