Air sampling for asbestos (1332214), 1,1,1-trichloroethane (71556), and trichlorotrifluoroethane (75694) as completed to determine the potential for carcinogenic exposure to film editing and cleaning employees at American Broadcasting Companies, Inc. (SIC-7814) in New York, New York on April 25 to 27, 1978. Epidemiological evaluations also were made. The Business Agent of Motion Picture Editors Local 771 of the International Alliance of Theatrical Stage Employees requested the survey on behalf of an unspecified number of workers. No asbestos fibers were detected. All concentrations of 1,1,1-trichlorethane and trichlorotrifluoroethane were below OSHA 8 hour time weighted average standards of 350 and 1000 parts per million, respectively. Two of five employees operating the ultrasonic film cleaning machines reported headaches, light headedness, loss of balance, and ringing in the ears, and four of five employees reported eye, nose, and throat irritation while loading and unloading the ultrasonic film cleaning machine and drying or defatting of skin when cleaning film by hand. The investigators conclude that a health hazard from solvent vapors did not exist during testing, and that further epidemiological studies should not be made. They recommend that high nose level warning signs be posted at entrances to film cleaning rooms, emergency personal protective equipment be available in case of major chemical spills, and that ultrasonic film cleaners use chemical safety goggles and impervious gloves during bulk film cleaning. Proper storage and labeling of bulk chemicals, maintenance of exhaust hoods, reconnection of the ventilation system, and inspection of the room air conditioning for possible cross contamination were also recommended procedures for ultrasonic film cleaning.
