Abstract
At the request of the management of C. F. and I. Steel Corporation (SIC-3315), an evaluation was made of worker exposure to 1,1,1- trichloroethane (71556) in two large vapor degreasers in the factory. The particular machine from which the vapors appeared to come was used to chop coils of galvanized wire into nails of various sizes and lengths. After the nails were chopped, they were passed through a vapor degreaser using a conveyor, packed and readied for shipping. Fifteen area samples were collected, six of which were breathing zone air samples ranging from 41 to 399mg/m3. None of the breathing zone samples exceeded the OSHA and NIOSH evaluation criteria of 1900mg/m3 although the levels were higher when the degreaser was in operation. General air samples ranged from 70 to 2218mg/m3. None of the workers had any medical problems which they felt were associated with their jobs. The author recommends that respiratory protection be provided if workers are working for extended time periods on top of the vapor degreasers. No one should be allowed to eat, drink or smoke in the work areas. The toxicology of 1,1,1-trichloroethane should be explained to the workers.
