Environmental and medical surveys were conducted on September 9, and October 4 and 26, 1979, to evaluate employee exposures to asbestos (1332214) fibers, 1,1,1-trichloroethane (71556), epichlorohydrin (106898), methylene-chloride (75092), methyl-ethyl-ketone (78933), phenylglycidyl-ether (122601), p,p-methylene-dianiline (101779), and methylene-bis-4-cyclohexylisocyanate (5124301) vapors in the Quonset hut potting and coating operations at the Fischer and Porter Company (SIC-3448) in Warminster, Pennsylvania. The evaluation was requested by the Independent Union of Rotameter Workers on behalf of an unspecified number of workers. The 8 hour time weighted average personal and area air samples were well within the environmental criteria for asbestos fibers and the various organic vapors. Concentrations ranged from 8.1 to 35.7 milligrams per cubic meter (mg/m3) for trichloroethane, from undetectable to 0.01mg/m3 for 4,4'- methylene dianiline, from undetectable to 0.1 fibers per cubic centimeter for asbestos, and were undetectable for epichlorohydrin, phenyl-glycidyl-ether, methyl-ethyl-ketone, methylene-chloride, and methylene-bis-4-cyclohexylisocyanate. The author concludes that the concentrations of all of the test substances were within acceptable limits. He recommends that protective clothes and equipment be used during various operations, that no smoking, eating, or drinking be allowed in any of the work areas, that ventilation units be monitored and maintained, and that a comprehensive medical surveillance and respiratory protection program be implemented.
