Breathing zone samples were analyzed for organotin compounds, copper (7440508), and xylene (1300716) during spray application of organotin containing marine antifouling paint at Norfolk Naval Shipyard (SIC-3731), Portsmouth, Virginia, March, 1984. The survey was part of a NIOSH study of occupational exposures to organotin compounds, conducted as a component of an assessment to determine the feasibility of conducting a study of reproductive effects. Company personnel records were reviewed. Work practices were observed. Organotin concentrations ranged from 0.02 to 0.2 milligram per cubic meter (mg/m3). Copper concentrations were 0.007 to 3.8mg/m3. Xylene concentrations ranged from 1.8 to 53 parts per million (ppm). The OSHA standards are: organotins (as tin), males, were potentially exposed to organotins. All workers wore respiratory protection. Although workers were required to remove all protective garments and shower before leaving the site, not all workers showered before leaving. The authors conclude that a potential exists for exposures to organotins and copper. As all employees were wearing respiratory protective equipment, actual exposures may be less than that indicated by the analytical data. The facility could contribute 16 potentially exposed workers to the reproductive effects study.
