Control Technology Assessment for Coal Gasification and Liquefaction Processes, Rockwell International, Santa Susana, California, Report No. CT-119-28a.
A control technology assessment was conducted at Rockwell International Corporation, Molten Salt Coal Gasification Process Development Unit (SIC-3312) in Santa Susana, California, on September 15, 1981. The purpose of the visit was to obtain information concerning engineering controls, work practices, and the monitoring program used to mitigate hazards associated with the molten salt coal gasification Unit. Potential hazards included coal dust, explosions, fires, noise, carbon-monoxide (630080), hydrogen- sulfide (7783064), molten sodium-carbonate (497198), sodium-sulfate (7757826), sulfur-dioxide (7446095), and asphyxiation from carbon- dioxide (124389). The company provided a medical surveillance program that included a complete work and medical history. Annual physical examinations consisted of blood tests, chest X-rays, audiograms, eye and hearing tests, electrocardiograms, and pulmonary function tests. A physical capability profile was outlined for each employee which included job restrictions and limitations. Work practices, and safety and certification programs were provided for employees. Worker exposures were minimized by the utilization of closed system operations. Natural dilution ventilation dissipated process emissions in workplaces. Engineering controls were supplemented by work practices and personal protective equipment as needed. The author concludes that gasifier stream sampling and maintenance and housekeeping activities are needed.
