Preliminary control technology assessment of TWA Maintenance Facility, Kansas City, Missouri.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, ECTB 106-18a, 1982 Jan; :1-7
An on site visit was made to the TWA Maintenance Facility (SIC- 3471), Kansas City, Missouri for the purpose of evaluating methods used to control worker exposures to hazardous materials. Electroplating operations were housed in a large brick building at the site and the processes used include silver cyanide, copper cyanide, cadmium cyanide, and chromic-acid (1333820) baths. Cleaning and stripping operations include perchloroethylene (127184) degreasers, sulfuric-acid (7664939), nitric-acid (7697372), hydrochloric-acid (7647010) and caustic solutions, and nickel cyanide strip. Most of the plating and cleaning tanks were equipped with local exhaust ventilation. Four of the chrome tanks also had sliding covers. Local exhaust systems vented from three sides of the tanks and exhausted downward through an exhaust tunnel in the floor of the building. An electrically operated roll up cover was attached to the perchloroethylene degreaser along with a refrigerator chiller. A large make up air unit supplied air to the plating shop. Face shields, respirators and other safety equipment was available. A nurse was on duty at all times and the industrial hygiene concerns of the facility were handled by two full time persons. The authors recommend this shop for a detailed survey because of the number of potentially hazardous operations.
