• Description:
  Worker exposures to various dusts, metals, and chemicals were surveyed on February 9 to 20, 1981 at two coal fired electrical power generating stations (SIC-4911) in Colorado Springs, Colorado. The evaluation was requested by the City of Colorado Springs Department of Public Utilities on behalf of the 72 workers at the Martin Drake and R.D. Nixon facilities. Breathing zone and area air samples were collected for analysis. Workers were exposed to fly ash and coal dust containing respirable free silica at concentrations that exceeded the respective OSHA standards of 5.0 and 2.0 milligrams per cubic meter (mg/cu m). Exposures to arsenic (7440382) also exceeded the OSHA standard of 0.01mg/cu m. Exposures to up to 0.1 part per million of hydrazine (302012) were detected when the agent was added to dilution vessels. No hazardous exposures to trace metals, chlorine (7782505), asbestos (1332214), amines, or mercury (7439976) were identified. Sulfur-dioxide (7446095) exposures were below the OSHA limit of 13mg/M³ but exceeded the NIOSH limit of 1.3mg/cu m. The author concludes that workers at these power stations are exposed to hazardous amounts of free silica in fly ash and coal dust, arsenic, hydrazine, and sulfur- dioxide. Recommendations are included for the use of respiratory protection, medical surveillance, hazard area designation, and engineering improvements.
