Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 80-065-780, 1980 Dec; :1-33
Air samples were analyzed for total dust and proteolytic enzymes, and employees were medically evaluated at the Clorox Company (SIC- 2840) in Jersey City, New Jersey, on April 29 and 30 and May 29 and 30, 1980. The evaluation was requested by an authorized representative of the Oil, Chemical and Atomic Workers International Union, Local 8-406 on behalf of 15 exposed workers. None of the 15 high volume area samples, which ranged from 0.002 to 1.57 micrograms per cubic meter, exceeded the 3.9 micrograms per cubic meter American Conference of Government Industrial Hygienists' threshold limit value for enzyme dust. Thirteen percent of the dust samples exceeded the 1.0 milligram per cubic meter dust specification. Medical evaluation of employees revealed the presence of upper and lower respiratory tract symptoms, skin rash and post shift wheezes. Three of the 12 exposed employees showed sensitization to the enzyme. There was a significant decrease in forced expiratory volume in one second at the end of the work shift. The authors conclude that some workers had become sensitized to the bacterial enzymes. They recommend reduction of the concentration of enzymes in the work environment.
