Abstract: MSHA is investigating refuge alternatives for use in underground coal mines. Refuge alternatives, such as rescue chambers, and other structures or systems, could be used to increase the survival of miners trapped underground. Section 13 of the Mine Improvement and New Emergency Response Act of 2006 requires the National Institute for Occupational Safety and Health (NIOSH) to study refuge alternatives. Section 112(b) of the Consolidated Appropriations Act of 2008 requires MSHA to propose regulations by June 15, 2008, consistent with the recommendations of NIOSH, requiring rescue chambers in underground coal mines,or facilities that provide at least the same measure of protection, and to finalize the regulations by December 31, 2008.
