Abstract
Worker exposures to metal dusts or fumes or acrylic vapors were determined at the Walter Reed Army Medical Center Dental Laboratory (SIC-8070) in Washington, D.C., from May 27 to 30, 1980. The evaluation request came from an authorized representative of the American Federation of Government Employees Local 2 on behalf of about 52 affected workers. Personal breathing zone air samples were analyzed for beryllium (7440417), nickel (7440020), chromium (7440473), molybdenum (7439987), and methyl-methacrylate (80626). Medical questionnaires were given to 17 workers. Air concentrations of all of the elements were well below OSHA standards of 0.002, 1.0, 5.0, 1.0, and 351 milligrams per cubic meter for beryllium, chromium, molybdenum, nickel, and methyl methacrylate, respectively. Two employees reported chronic lung conditions which they attributed to past dust exposure. Ventilation measurements indicated that air flow rates were sufficient to remove metal and porcelain dusts, and acrylic vapors. The author concludes that the workers are not exposed to chemical hazards. Recommendations include the repair of certain components of the ventilation system, worker education, measures to minimize dust generation, and the prohibition of eating, drinking and smoking when working in the laboratory.
