Industrial Hygiene Survey Report Of Worker Exposures To Organotins At Red Panther Chemical Company, Clarksdale, Missippi, Report No. IWS-136-12.
NIOSH 1985 Jun:27 pages
Breathing zone samples were analyzed for tricyclohexyltin-hydroxide (13121705) (TCHH) at Red Panther Chemical Company (SIC-2879, SIC- 5191), Clarksdale, Mississippi in June, 1984. The survey was part of a NIOSH study for occupational exposure to organotins, as a component of an assessment to determine the feasibility of conducting a reproductive effects study. The samples were taken during production of a miticide containing TCHH. Company personnel records were reviewed. Work practices were observed. Organotin concentrations, reported as tin, ranged from 0.07 to 3.4 milligrams per cubic meter (mg/m3), corresponding to 0.2 to 11mg/m3 TCHH. The OSHA standard for organotin compounds, as tin, is 0.1mg/m3. Twenty four potentially exposed male workers were identified. All employees in the formulation area were required to wear respiratory protection, although some workers wearing dust masks used only the upper strap to hold them in place. The authors conclude that most workers were exposed to organotin concentrations that exceeded the OSHA limit. TCHH concentrations should be reduced by improving local exhaust ventilation. The facility could contribute 24 potentially exposed workers to the NIOSH reproductive effects study.
