Abstract	An industrial hygiene survey at Dorchester Refining Company (SIC-1799), Mount Pleasant, Texas was conducted in September and October, 1981. The purpose of the survey was to determine exposure of the workers in turn around operations at the thermal catalytic cracking unit. More than 40 chemical agents were identified and quantitated. Excessive exposures of nitrogen-dioxide (10102440), chromium (7440473), hexavalent chromium (18540299) (Cr(VI)), iron (7439896), and total fumes occurred during welding operations. The author concludes that Cr(VI) represents the most hazardous exposure at the facility. Recommendations include breathing zone monitoring, using protective clothing and equipment, and checking ventilation rates.
