Possible health hazards due to worker exposure to chlorinated isocyanurates at Olin Chemical (SIC-286), Lake Charles, Louisiana were investigated. The study was requested by Local 407 International Union of Operating Engineers and was performed on November 3 and 4, 1981. At the time of the survey about 90 workers were employed in production activities associated with packaging trichloroisocyanuric-acid (87901) (TCCA) and sodium- dichloroisocyanurate (2893789) (NaDDC). Personal breathing zone sampling and medical interviews were performed. Particulate concentrations ranged from 0.11 to 38 milligrams per cubic meter. About 60 percent of the dust near the packaging areas was within the respirable size range. No OSHA standards for exposure to any chlorinated isocyanurates have been developed. Workers used respirator facepieces with high efficiency particulate filters. All production workers reported one or more work related symptoms. The most common symptoms were eye irritation and cough. Seventy eight percent of the women interviewed reported problems or changes in their menstrual cycle since beginning work in the packaging area. The authors conclude that workers are not adequately protected from the irritant effects of TCCA and NaDDC. Engineering controls, medical surveillance, respiratory protection and improved housekeeping procedures are recommended.
