NIOSH Comments on the Mine Safety and Health Administration Notice on Coal MineRespirable Dust Standard Noncompliance Determinations by R. A. Lemen, May 20, 1994

摘要

The testimony summarized information and comments from NIOSH regarding exposureto coal dust. The Mine Safety and Health Administration (MSHA) intends to improve the enforcement of the standards for coal mine dust by modifying the procedure used to classify inspector collected measurements of respirable coal mine dust. NIOSH commends the proposal to increase the protection of miners by reducing exposures which are currently in excess of the respirable dust standard. By enforcing the respirable coal mine dust standard without any upward adjustment, MSHA will provide an equitable sampling program, given frequent sampling, in which the burden of measurement uncertainty is shared equally by miners and operators.
