Control Technology Assessment for Coal Gasification and Liquefaction Processes, University of Minnesota Heating Plant FW-Stoic Gasification Facility, Duluth, Minnesota. Report for the Site Visit of January 1981

摘要

A control technology assessment was conducted at the University of Minnesota, Duluth Campus Heating Facility (SIC-4961), Duluth, Minnesota on January 19 and 20, 1981 to study measures to control worker exposures to hazardous physical and chemical agents at the Foster Wheeler Stoic Gasification Facility. The University and the Oak Ridge National Laboratory had developed and implemented an industrial hygiene program designed specifically to address the potential hazards at the gasification site. Major health hazards were carbon-monoxide (630080), heat stress, coal dust, polynuclear aromatics, and noise. Exposure to coal dust was controlled by respirators with high efficiency filters. Control of carbon-monoxide was continuously monitored. Mufflers were installed to reduce noise. The author recommends changes in seals and flanges to avoid leakage, the use of supplied air instead of air purifying respirators, mandatory, compliance with health and safety programs, clean and dirty change room facilities, restricted access to clean areas by contaminated workers, use of escape type respirators, and monitoring of dermal exposure to tars.
