Abstract
Personal and area air samples were analyzed for common laboratory solvents used in radioimmune assays at the Department of Pharmacology, West Virginia University Medical Center (SIC-0867), Morgantown, West Virginia in October 1979. The evaluation was requested by a representative of the Department out of concern for chronic excessive exposure to the solvents. Samples were analyzed for acetone (67641), benzene (71432), chloroform (67663), 2,2,4- trimethylpentane (540841), methanol (67561), and toluene (108883). Work practices and ventilation system performance were evaluated. Air concentrations of the solvents were below all relevant federal standards. Good work practices were used by the laboratory technicians. Storage practices were deficient. Some chemicals were stored overhead, and used scintillation vials were emptied into large containers that were not sealed or ventilated. Laboratory hoods had inadequate face velocities for working with toxic chemicals. The author concludes that although airborne solvent concentrations were below federal standards, there is a risk of excessive exposure due to poor handling and storage of chemicals and the defective hoods. Recommendations include adjusting hoods to conform to NIOSH standards, not storing chemicals overhead, and proper and prompt disposal of used scintillation vials.
