In response to a request from the International Brotherhood of Electrical Workers, Local 702, an evaluation of possible health hazards was undertaken at the Culley Generating Station of the Southern Indiana Gas and Electric Company (SIC-4911), Yankeetown, Indiana. At the time of the study exposures to most airborne contaminants were low. Two samples taken in areas near the boilers were above the NIOSH recommended limit of 1.3 milligrams per cubic meter (mg/m3) for sulfur-dioxide (7446095). The highest coal dust level for this facility was 1.31mg/m3. The highest fly ash concentration in personal samples was 0.26mg/m3. Medical reports on the 173 employees were reviewed, yielding four cases of pneumoconiosis among men with an average employment period at this facility of 24 years. Three of the four were equipment operators, and the fourth was an electrician with responsibilities over the entire facility. The authors conclude that a hazard existed for some workers exposed to sulfur-dioxide, and that a potential hazard existed due to boiler leaks. The authors recommend that the respiratory protection program be upgraded and that employees be trained in the use and care of respirators. Environmental and medical monitoring of the employees should be increased. A joint labor/management health and safety committee should be established. Leaking seals on coal mills and other equipment should be repaired. All exposed insulation should be wrapped or covered. A heat stress survey should be conducted for those working on the boiler units and operating dozers. Regularly scheduled maintenance operations should be designed for boiler units.
