Vinyl Bromide. Industrial Hygiene Survey Report.
NIOSH 1977 Oct:17 pages
An industrial hygiene survey was conducted at the Ethyl Corporation (SIC-2879), in Magnolia, Arkansas, on March 23 and 24, 1977. Air samples were collected to determine current worker exposures to vinyl-bromide (593602) (VBr). The company employed a part time physician for physical examinations and biological sampling. The facility had an active safety committee and provided industrial hygiene services. The facility was engaged in the manufacture of ethylene-dibromide (106934) (EDB). There were 140 employees. Time weighted averages for VBr operators were 0.27 parts per million (ppm) VBr and 0.08ppm EDB; for lab technicians, exposures were average exposures pose no immediate dangers. Control measures at the facility are effective in maintaining low exposures to personnel during normal operations. Respirators should be worn by tank car loaders when opening or inspecting tanks or valves, venting tanks, or collecting samples.
