Personal and area air samples were collected in two film laboratories (SIC-7819) in Hollywood, California for formaldehyde (50000), acetic-acid (64197), and organic solvents. Evaluation was requested by the Film Technicians Local No. 683 and was performed in 1980 and 1981. A medical questionnaire was distributed. Formaldehyde concentrations were below California/OSHA standards of 2 parts per million in one laboratory. Acetic-acid was under the limit of detection of 0.05 milligrams. In the second laboratory, organic vapor and acetic-acid were below evaluation criteria except for methyl-chloroform (71556) which showed one area sample concentration of 4431 milligrams per cubic meter (mg/m3) (NIOSH standard is 1900mg/m3) but this was not an area where employees were normally exposed. Formaldehyde concentrations in this laboratory occasionally exceeded evaluation standards 5 fold. Symptoms reported were: persistent irritant contact dermatitis; eye and upper respiratory irritation; transient defatting dermatitis; and anesthetic effects on fingers. The group exposed to final products reported irritation to eyes and upper respiratory system. The bleach accelerator process produced severe dermatitis in a high proportion of workers; organic solvents and residual formaldehyde in final products produced milder symptoms. The authors conclude that employees are overexposed only to formaldehyde at one laboratory.
