Vinyl fluoride and vinyl bromide industrial hygiene survey report.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. 79-111, 1978 Nov; :1-27
Industrial hygiene surveys were conducted at a vinyl-fluoride (75025) (VF) manufacturing facility, a VF polymerization facility, and a vinyl-bromide (593602) (VBr) manufacturing company from March to June, 1977 to determine worker exposures to these substances and to document engineering controls, work practices, administrative controls, and biological and environmental sampling requirements used by the companies. Exposures for VF production operators were less than 2 parts per million (ppm); potentially higher exposures were possible during operations start up. In the VF polymerization facility, time weighted average (TWA) exposures to VF for polymer operators were 1 to 5ppm, with an average of 1.9ppm. In the VBr factory, the median TWA exposure to VBr for operators was 0.27ppm. For a loading crewman at this factory exposure was 6.3ppm over a 1 hour period. The author concludes that the integrity of the process systems is maintained sufficiently in all facilities to present minimal exposure hazards to workers. Measures recommended to minimize exposure include the institution of a surveillance program; the design and installation of leak resistant, enclosed process systems; provision of respiratory protection and protective clothing; employee education and training; installation of eyewash fountains and emergency showers; and the use of personal protective equipment to minimize skin and eye contact with the chemicals.
