NIOSH and MSHA jointly review and approve this type of respirator used for mine emergencies under 42 CFR pt. 84, Approval of Respiratory Protective Devices. NIOSH also approves these respirators used in other work environments where escape equipment may be provided to workers, such as vessels operated by U.S. Navy and Coast Guard personnel. The proposed rule would replace only those technical requirements in 42 CFR Part 84--Subpart H that are uniquely applicable to closed-circuit escape respirators (CCERs), a subset of the variety of escape respirators presently covered by Subpart H.
