Study of Coal Liquefaction and Gasification Plants: An Industrial Hygiene Assessment, a Control Technology Assessment, and the Development of Sampling and Analytical Techniques. Volume 2. Industrial Hygiene Study of Coal Gasification Processes

摘要

Environmental and breathing zone samples were analyzed for polynuclear aromatic (PNA) compounds including polycyclic aromatic hydrocarbons and aromatic amine, benzene (71432), toluene (108883), xylene (1330207), anilines, phenols, carbon-monoxide (630080), and hydrogen-sulfide (7783064) at three coal gasification (SIC-3312) facilities. Industrial hygiene programs were reviewed. The other substances were rarely found at concentrations above the detection limit. All facilities provided physical examinations and periodic medical histories. Two provided skin examinations, urinalyses, and blood counts. Work practices were directed toward reducing skin contact with process components. These included isolation, draining and flushing, and cleaning. The authors conclude that workers at all facilities are exposed to PNA. They recommend developing methods for decontaminating protective clothing and equipment, and conducting studies on long term effects of PNA inhalation.
