Engineering and Administrative Noise Controls for the Mining Industry

摘要

The U.S. Mine Safety and Health Administration's (MSHA) health standard for occupational noise exposure (30 CFR Part 62), became effective on September 13, 2000. An important feature of this revised noise standard is the emphasis it places on implementing and using feasible engineering and administrative noise controls to maintain a miner's noise exposure at or below the permissible exposure level (PEL). In an attempt to help answer questions regarding the feasibility of engineering and administrative noise controls, MSHA developed and issued a Program Information Bulletin (PIB) 04-18, "Technologically Achievable, Administratively Achievable, and Promising Noise Controls (30 CFR Part 62)." This article discusses the terms 'feasible,' 'achievable,' and 'promising' in terms of engineering and administrative noise controls.
