Abstract
An evaluation of possible hazardous exposure to sulfuric-acid (7664939) mist was made at the solvent extraction electrowinning facility of the Cities Service Company, Miami, Arizona, in response to a request from the United Steelworkers of America, Local 4338. This facility produced about 30,000 pounds of marketable 99.9 percent pure copper cathode daily, and transient mucous membrane irritation and splash burns had been reported. Samples of breathing zone and area air were taken. Sulfuric-acid concentrations in these samples approached but did not exceed recommended limits. Physical examinations of seven exposed employees (three female, four male, aged 24 to 41) showed conjunctivitis, skin rashes, and greenish black dental discoloration, signs which are closely associated with exposure to sulfuric-acid mist. The authors recommend that for each employee with possible exposure to the acid, a complete medical history and physical examination be done along with x-ray surveillance of lungs. Periodic pulmonary function tests should be performed. Impervious protective clothing and eye protection should be worn by workers, and clothing wet with acid should be removed immediately. Protective clothing should be changed at least twice a week. Full length, 8 inch minimum plastic shields can be used in place of, or in addition to, goggles. Respirators should be used appropriately and workers should be educated as to sulfuric-acid hazards.
