Environmental and personal air samples were evaluated for coal dust, fly ash dust, sulfur-dioxide (7446095), benzene (71432) solubles, and asbestos (1332214) at the Hatfield's Ferry Power Station (SIC- 4911) Masontown, Pennsylvania, on December 11, 1980, February 26 and 27, 1981, and September 26, 1981. The evaluation was requested by a representative of the Utility Workers Union of America, AFL-CIO, Local 102, on behalf of 117 workers. Medical evaluation of 71 workers included: an occupational history and respiratory symptom questionnaire, chest examination, and blood pressure measurement. NIOSH standards for total dust (coal) and respirable coal dust are 3.9 milligrams per cubic meter (mg/m3) and 2.0mg/m3, respectively. The ranges for the air samples were 0.4 to 4.5 4.5mg/m3 for total dust and 0.06 to 2.6mg/m3 for respirable coal dust. Air samples for fly ash dust ranged from 0.4 to 56mg/m3, with a NIOSH standard of 10mg/m3. Sulfur-dioxide, sulfates, and asbestos samples were well below NIOSH criteria. The authors conclude that there are potential overexposures to coal dust and fly ash dust. They recommend wet or vacuum cleanup methods and the mandatory use of respirators in dusty environments. Preplacement, periodic medical examinations and air monitoring for coal dust and fly ash are recommended.
