Abstract
Exposures to boiler gases and coal dust were surveyed in August 1981 at Warrick Generating Station (SIC-4911), Yankeetown, Indiana. Evaluation was requested by the International Brotherhood of Electrical Workers, Local 702, on behalf of 165 workers. Air samples were collected for nitrogen-dioxide (10102440), nitric-oxide (10102439), sulfur-dioxide (7446095), coal dust, fly-ash, silica (14808607), and inorganic metals. Boiler units were checked for leaks. Questionnaires and medical examinations were completed. One of 22 personal samples for coal dust exceeded the OSHA standard of 2.4 milligrams per cubic meter. All other substances in the personal samples were within OSHA limits. Boiler leaks were found on the positive pressure boiler unit. Sulfur-dioxide concentrations in the boiler gas samples ranged from 15 to 20 parts per million (OSHA standard is 5 parts per million for an 8 hour time weighted average). Workers complained of cough, breathlessness, or wheezing. No deficits occurred in respiratory function tests. No cases of pneumoconiosis were found. The authors conclude that workers are exposed to high concentrations of sulfur-dioxide, coal dust, and crystalline silica. They recommend respiratory protection, maintenance of boiler units and seals, a heat stress survey for boiler units and dozer operators, and removal of asbestos insulation in the lunchroom oven.
