Working conditions were evaluated in Building 84, at the Lockheed/Georgia Company (SIC-3721), Marietta, Georgia where parts removed from C54 aircraft wings were spray cleaned with 1,1,1- trichloroethane (71556) or a solvent blend called Turco T-1000. An authorized representative of the Aeronautical Machinists and Aerospace Workers, Lodge 709, had requested the evaluation to investigate health hazards in Building 84. Air samples taken near an exhaust ventilation booth were analyzed for solvents. Personal air sampling detected exposures at concentrations well below NIOSH evaluation criteria: 23 parts per million (ppm) 1,1,1- trichloroethane, 350ppm limit; 5.8ppm methylene-chloride (75092), 75ppm limit; 2.8ppm tetrachloroethylene (127184), 50ppm limit; 1.2ppm aromatic hydrocarbons, 25ppm limit; 0.2ppm diacetone-alcohol (123422), 50ppm limit; 0.5ppm n-butanol (71363), 50ppm limit; and total urinary trichloro compounds and m-methyl-hippuric-acid were within or below normal levels. The authors conclude that no solvent exposures above NIOSH recommended levels were detected during the evaluation. Differences noted in neurobehavioral performance between exposed and unexposed workers can not conclusively be attributed to solvent exposures received prior to the NIOSH site visit. As tetrachloroethylene is a suspected carcinogen, exposures should be reduced to the lowest technically feasible limit.
