Control Technology Assessment for Coal Gasification and Liquefaction Processes, Westinghouse Fluidized-Bed Coal Gasification Process Development Unit, Waltz Mill, Pennsylvania. Report for the Site Visit of June 1981

摘要

A control technology survey was conducted at the Westinghouse Fluidized Bed Coal Gasification Process Development Unit (SIC-5161) in Waltz Mill, Pennsylvania on June 24 and 25, 1981, to assess measures being developed to prevent occupational exposures to hazardous agents. The pressurized, fluidized bed gasification process was developed to convert coal to gas for industrial or utility fuel. Potential hazards identified included coal dust and product gas because of their explosive and flammable nature, and exposures to hydrogen-sulfide, (7783064), carbon-monoxide (630080), and polynuclear aromatics found in liquid coal products. Field operators, maintenance workers, and laboratory technicians were those most likely to be at risk. Work practice guidelines were designed to supplement engineering controls to provide additional protection in hazardous areas. Inspections and surveys were performed periodically. Limited access was allowed to and from the process development unit (PDU), and appropriate safety equipment was required. Job performance protocols were established. Employee education and training programs were instituted. Physical examinations were given annually to PDU workers. The author recommends the use of rubber instead of cotton gloves. PDU personnel should carry a portable carbon-monoxide meter. Supplied air respirators should be used when changing recycle gas compressor filters and strainers.
