A walk through survey was conducted at St. Mary's Carbon Company (SIC-3624), St. Mary's, Pennsylvania, in March 1983. The company produced carbon replacement automotive parts such as brushes, seals, and rings. The raw materials used were petroleum coke and coal-tar- pitch (61789604). There were about 166 employees (70 percent males and 30 percent females) working in two shifts. Preemployment physicals were given to all employees, but did not include pulmonary function or hearing tests, or chest X-rays. Periodic medical examinations were not given, and no nurse was employed. Several employees were trained in first aid. Engineering modifications were made to decrease employee exposure to airborne contaminants. All machinery in the finishing areas were equipped with permanent ventilation equipment. Hoods were installed for kiln graphitizing furnaces. Canopy type hoods were installed above heated rotary mixers in the mixing department. A stationary ventilation duct was installed in the assembly department. Dilution ventilation was used throughout most of the facility. The author concludes that the extent of employee exposures to polyaromatic hydrocarbons should be assessed and byproducts of soldering and welding operation should be evaluated. An indepth study of this facility is not recommended because work histories date back only to 1977.
