Health hazard evaluation report: HHE-80-026-904, United States Steel, Tubing Specialties Center, Gary, Indiana.

Worker exposures to benzene (71432), xylene (1330207) and coal tar naphtha (8030306) were surveyed on January 15, February 12, and October 28, 1980 at United States Steel, Tubing Specialties (SIC- 3317) in Gary, Indiana. The evaluation was requested by a representative of the United Steelworkers, Local 2697, on behalf of 12 employees involved in spray pipe coating operations. Personal air samples were collected, and four workers were questioned about work related health effects. Exposures to benzene, xylene, and coal tar naphtha ranged from 0.02 to 0.47, 1.2 to 1.8, and 7 to 18 parts per million (ppm), respectively; corresponding OSHA standards are 10, 100, and 100ppm for an 8 hour workday. The employees did not report any health problems. The author concludes that exposures to the three test chemicals are within acceptable limits, however due to the potential carcinogenicity of benzene, all exposures to this chemical should be minimized. The company has planned to substitute a new pipe coating that contains no benzene; this should eliminate any potential exposure. The author recommends toxicity evaluation of the new product, and introduction of exposure controls if necessary.
