Study of Coal Liquefaction and Gasification Plants: An Industrial Hygiene Assessment, a Control Technology Assessment, and the Development of Sampling and Analytical Techniques. Volume 1. Industrial Hygiene Study of Coal Liquefaction Processes

摘要

Environmental and personal samples were analyzed for polynuclear aromatic (PNA) compounds including polycyclic aromatic hydrocarbons and aromatic amines, benzene (71432), toluene (108883), xylene (1330207), anilines, phenols, carbon-monoxide (630080), and hydrogen-sulfide (7783064) at five coal liquefaction (SIC-3312) pilot facilities. The industrial hygiene programs were reviewed. The most significant exposures were from PNA. Highest PNA exposures were connected with maintenance activities in the process areas. Most occupational health programs included a preemployment physical, annual checkups, and a termination physical. Protective clothing was provided by all facilities, however, most facilities did not monitor clothing or personnel for residual contamination. The authors conclude that workers at all facilities are exposed to PNA. Recommendations include establishing a standardized medical monitoring protocol and developing methods for decontaminating protective clothing and equipment.
