Abstract
Personal breathing zone and area air samples were taken and affected employees were interviewed to determine whether exposures to polymethyl-methacrylate (9011147) methyl-methacrylate-vapor (80626) and 1,1,1-trichloroethane (71556), toluene (108883), magnesium- fluoride (7783406) isopropyl-alcohol (67630), iron-oxide (1345251), and oil mist were posing a health hazard to massive optics (M.O.) and tool grinding room (T.G.) employees of U.S. Precision Lense Incorporated (SIC-307) in Cincinnati, Ohio, on January 17 and 18, 1980. The evaluation was requested by the company. The facility employs 250 workers with an unspecified number working in the M.O. and T.G. rooms. Personal breathing zone and area air samples were taken and analyzed of each for the contaminants. Bulk samples were analyzed for silica content. Sample results for the contaminants ranged up to 20 percent of the recommended exposure limits. Bulk samples did not contain silica. The authors conclude that the exposures to the sampled substances were not hazardous to the employees at the time of the investigations.
