I. Walk-Thru Industrial Hygiene Survey, The Harshaw Chemical Company Gloucester City, New Jersey.
NIOSH 1975 Jun:6 pages
Work conditions and processes were evaluated on May 14 and 15, 1975 at the production facilities of the Harshaw Chemical Company (SIC- 2819) in Gloucester City, New Jersey. Antimony-oxide (1327339) production began at the factory in 1951, and the operation involved 17 operators and 4 maintenance men. No full time medical or safety personnel were employed, but periodic X-rays and biological monitoring for antimony (7440360) was provided. Safety shoes, respirators, and air supplied hoods were used, and showers and work clothing were supplied. Antimony-oxide dust was seen on the equipment, walls, and floor. A major dust problem occurred at the bagging station, where the wrong size bags were used. This caused the generation of a cloud of antimony-oxide dust every time a bag was filled. Company officials reported that the concentrations of antimony and arsenic (7440382) in the workplace air exceeded threshold limit values. The authors recommend that proper size bags be used in bagging operations to reduce dustiness and that a stall type hood with slot type ventilation be provided at the bagging station. They note that air sampling will be conducted at a future time, and that the results will reveal other hygienic problems at the factory.
