Engineering health hazard control technology for coal gasification and liquefaction processes. Final report.
NIOSH 1983 :1-105
A study was conducted to document hazard control technology options which provide effective protection for the safety and health of workers involved in the conversion of coal to supplement petroleum and natural gas supplies. These workers had the potential of being exposed to toxic materials from leaks and spills from process and waste streams during normal facility operation and during maintenance. Additional hazards of heat and noise, and danger from spontaneous combustion fires and explosions were also noted. The principle hazards discussed in relation to coal conversion included exposure to coal derived liquids, carbon-monoxide (630080), and hydrogen-sulfide (7783064). Such liquids were highly aromatic and contained polyaromatic hydrocarbons and aromatic amines associated with carcinogenic and mutagenic effects. Recommendations were offered for engineering controls and for changes in work practices which would reduce potential exposures. Methods were described for removal of ash, particulates, tar, and acid gases. Process descriptions were included for each step of the coal liquefaction and gasification processes. Recommendations were also included for design and layout of the processes and equipment, the selection of equipment, health and safety monitoring programs, and research needs for future study.
