Respirable Coal Mine Dust: Continuous Personal Dust Monitor (CPDM)

This document requests information related to the use of the Continuous Personal Dust Monitor (CPDM) as a sampling device to measure a miner's exposure to respirable coal mine dust. In September 2006, the National Institute for Occupational Safety and Health (NIOSH) published the results of a collaborative study designed to verify the performance of the pre-commercial CPDM in laboratory and underground coal mine environments. According to the NIOSH Report of Investigations 9669, "Laboratory and Field Performance of a Continuously Measuring Personal Respirable Dust Monitor," the CPDM is a new monitoring device that is accurate, precise, and durable in providing continuous exposure information previously not available to coal miners and coal mine operators. MSHA is requesting information regarding whether the use of the CPDM would lead to more effective monitoring and control miners' exposure to respirable coal mine dust during a working shift. Responses to this request for information will assist MSHA in determining: How to best use the monitoring capability of the CPDM to improve miner health protection from disabling occupational lung disease; the feasibility of more effective exp
