Title: Proximity Detection Systems for Underground Mines

Abstract: The Mine Safety and Health Administration (MSHA) will issue an emergency temporary standard (ETS) under section 101(b) of the Federal Mine Safety and Health Act of 1977 in response to the grave danger that miners face when working near mobile equipment in underground mines. MSHA has concluded, from investigations of accidents involving mobile equipment and other reports, that immediate action is necessary to protect miners. To date, in 2010, there have been five fatalities resulting from crushing and pinning accidents. Mobile equipment can pin, crush, or strike a miner working near the equipment. Proximity detection technology can prevent these types of accidents. The ETS would strengthen the protection for underground miners by reducing the potential of pinning, crushing or striking hazards associated with working close to mobile equipment. As a part of the Secretary's strategy for securing safe and healthy workplaces, the Mine Safety and Health Administration will undertake regulatory action related to reducing injuries and fatalities to workers in close proximity to moving equipment and vehicles.

Statement of Need: Mining is one of the most hazardous industries in this country. Miners continue to be injured or killed resulting from pinning, crushing, or striking accidents involving mobile equipment. Equipment is available to help prevent accidents that cause debilitating injuries and accidental death.

Summary of the Legal Basis: Promulgation of this standard is authorized by section 101(b) of the Federal Mine Safety and Health Act of 1977 as amended by the Mine Improvement and New Emergency Response Act of 2006.

Alternatives: No reasonable alternatives to this regulation would be as comprehensive or as effective in eliminating hazards and preventing injuries.

Anticipated Costs and Benefits: MSHA will develop a regulatory economic analysis to accompany the ETS.

Risks: The lack of proximity detection systems on mobile equipment in underground mines contributes to a higher incidence of debilitating injuries and accidental deaths.
