HHE Report No. HETA-81-015-898, Bradford Western Corporation, Arvada, Colorado.
Environmental and breathing zone samples were analyzed for titanium- dioxide (13463677), xylene (1330207), n-butanol (71363), and 1,1,1- trichloroethane (71556) at the Bradford Western Corporation (SIC- 3444), in Arvada, Colorado, on March 17, 1981. Medical interviews were also conducted with workers. An employee from a company in an adjacent warehouse requested the evaluation on behalf of approximately four workers. No titanium-dioxide was detected. Xylene concentrations ranged from 0.45 to 0.64 milligrams per cubic meter (mg/cum), compared with the OSHA standard of 435mg/cum, while 1,1,1-trichloroethane concentrations ranged from 0.54 to 1.62mg/cum, considerably less than the OSHA standard of 1900mg/cum. No n- butanol was detected. The authors conclude that a health hazard from the tested chemicals did not exist. They recommend that the employer brief employees on any new chemicals introduced into the assembly process, and reassess the ventilation system if any new raw materials are used.
