Environmental samples were analyzed for vinyl-chloride (75014), styrene (100425), benzene (71432), and hydrogen-chloride (7647010) at New York Telephone and Telegraph Company (SIC-4811), New York City, in October, 1974. The survey was requested by an authorized employee representative to evaluate a potential hazard to cable splicers from vinyl-chloride gas. Personal air samples were collected using charcoal sampling tubes. There were no detectable amounts of any of the compounds for which analyses were made. The time weighted average threshold limits for benzene and styrene are 10 parts per million (ppm) and 100ppm, respectively. The short time exposure limit for hydrogen-chloride is 5ppm. The NIOSH time weighted average threshold limit for vinyl-chloride is the limit of detectability. The author concludes that since the concentrations of benzene, styrene, vinyl-chloride, and hydrogen-chloride were below detectable limits, there is no health hazard for cable splicers.
