A study was requested by the Oil, Chemical and Atomic Workers International Union at Phillips Petroleum Company Refinery (SIC- 2911), at Woods Cross, Utah. Possible correlation between aplastic anemia, exposure to hydrogen-fluoride (7664393) (HF), and suspected cancer deaths was investigated. Air samples were analyzed for organic vapors, lead (7439921), and HF. Blood counts, blood lead and free erythrocyte protoporphyrin (FEP) concentrations, and pulmonary function were measured. One benzene (71432) sample (8.8 milligrams per cubic meter) (mg/m3) exceeded the NIOSH 3.2mg/m3 criterion. Samples of toluene (108883), lead, and xylene (1330207) were below NIOSH recommended exposures: 375mg/m3, 0.05mg/m3, and 435mg/m3, respectively. Only one HF sample approached the 2.5mg/m3 NIOSH evaluation criterion. Five workers reported symtoms suggesting overexposure to organic solvents; five reported breathing problems. No longterm effects on pulmonary function from HF exposure were confirmed; no clinically significant blood abnormalities except one case of aplastic anemia. Blood lead and FEP concentrations were within normal range. Data did not warrant further study of increased cancer incidence. The authors conclude that exposure hazards from various petroleum products exist (laboratory and gas loading dock). There are no lasting ill effects from HF exposure. Respiratory protection practices are recommended.
