NIOSH Testimony on Respirable Dust by B. T. Scheib, July 1978.
NIOSH 1978 Jul:20 pages
This testimony concerns the view of NIOSH with regard to respirable dust hazards in the workplace, specifically coal mine dust and silica (14808607). The following issues are discussed: whether the proposed definition of respirable dust should include a particle size limitation; whether the definition of respirable dust should require conversion of the measurement of other approved instruments to an MRE equivalent; whether a standard higher or lower than 2.0 milligrams of respirable dust per cubic meter of air is medically acceptable; whether a standard higher or lower than the proposed standard for respirable dust when free silica is present is medically acceptable and reasonable; whether area sampling should be used to determine compliance with other sections; and whether the frequency and number of samples required by the proposed rule should be changed.
