• Description:
  In response to a request from the State of Alaska Department of Labor, a study was made of employee exposure to oil sludge and vapors during oil sludge removal and maintenance activities at the Alyeska Pipeline Service Company's Ballast Water Treatment Facility (SIC-1311), Valdez, Alaska. Hydrogen-sulfide (7783064) concentrations were less than 0.1 part per million (ppm) when no one was working in the ballast water tank, and 0.6ppm during work operation. Phenol (108952) concentrations were below 0.01ppm. Polynuclear aromatic hydrocarbon concentrations showed only detectable levels of acenaphthylene (208968), acenaphthene (83329), fluorene (86737), phenanthrene (85018), anthracene (120127), and naphthalene (91203). Benzene (71432) concentrations in the tank ranged from 4.2 to 5.9mg/m3 with no activity in the tank and from 6.0 to 15.4mg/m3 during work
  
  the proposed benzene standard is 1ppm. Toluene (108883) concentrations ranged from 3 to 10ppm. Xylene (1330207) concentrations ranged from 9 to 21ppm. Total hydrocarbons, except benzene, toluene, and xylene, showed concentrations from 371 to 1228mg/m3. Of eight maintenance workers, five reported headache, dizziness, or nausea when working without a respirator. The authors conclude that workers were potentially exposed to benzene vapors and total hydrocarbon vapors exceeding the evaluation criteria for these substances. The authors recommend the use of respiratory protection measures to reduce exposures during work operations.
