An industrial hygiene survey was conducted at the Stauffer Chemical Company (SIC-2874), Salt Lake City, Utah, on July 16-25, 1975, as part of a study of variations in worker exposures in different wet chemical operations. The operation evaluated was the cleaning of a large phosphoric-acid (7664382) reactor vessel. Samples were taken for 8 hour time weighted average exposures for cadmium (7440439), chromium (7440473), vanadium (7440622), phosphoric-acid, and sulfuric-acid (7664939) on workers involved in the cleaning. General area samples were collected for fluorides, radon (10043922), particle size distribution and uranium (7440611). All contaminants were below the current legal standard, but there was an irritating material present in the tank environment. It is recommended that the good work practices for tank entry be continued. The radiation levels were very low which would have made this facility ideal for determining if exposure to phosphoric-acid results in an increased incidence of cancer, but medical and personnel records were not adequate.
