Mine Shift Atmospheric Conditions; Respirable Dust Sample

The Mine Safety and Health Administration (MSHA) is extending the public comment period on the joint notice with the National Institute for Occupational Safety and Health (NIOSH) proposing a finding that the average concentration of respirable dust to which each miner in the active workings of a coal mine is exposed can be measured accurately over a single shift. MSHA and NIOSH will conduct a public hearing.
