Information Profiles on Potential Occupational Hazards: Sulfur Tetrafluoride.
Center for Chemical Hazard Assessment, Syracuse Research Corporation, Syracuse, New York, Report No. SRC TR 81-549 1981 Apr:12 pages
Information on the potential occupational hazards from sulfur- tetrafluoride (7783600) was reviewed. Topics discussed included chemical and physical properties, production, use, manufacturers and distributors, manufacturing processes, occupational exposures, and biological effects. Production was estimated to be between 1,000 and 10,000 pounds per year. Sulfur-tetrafluoride is used as a chemical fluorinating agent, a water repellency treatment, and to reduce friction in elastomers. A national survey indicated that approximately 1,200 workers are potentially exposed to sulfur- tetrafluoride. Studies have indicated that sulfur-tetrafluoride is highly toxic, irritating and corrosive to skin, eyes and respiratory system. Studies in rats showed that sulfur-tetrafluoride at 19 parts per million was lethal to one of two rats exposed for 4 hours. A subchronic study showed that rats exposed to 4 parts per million for 4 hours/day for 10 days developed labored breathing, weakness and nasal discharge; after a 14 day recovery period, no significant pathological changes were seen on autopsy. No information was found on carcinogenicity, mutagenicity, or teratogenicity.
