Description:Airborne dust concentrations were measured at the E.M.J.D. Corporation (SIC-3444) Englewood, Colorado on February 9, 1982. The facility manager requested the survey to evaluate 10 employees who were exposed to total particulate and metal dusts in the electronic sheet metal fabrication area. The entire facility employed 23 people. Breathing zone air samples were collected and medical questionnaires were completed. The 8 hour time weighted average (TWA) exposure to total airborne particulates ranged from 0.15 to 2.27 milligrams per cubic meter of air (mg/m3). Iron (7439896) particulates ranged from 0.01 to 0.09mg/m3 per 8 hour TWA, while comparable values for aluminum (7429905) were 0.010 to 0.29mg/m3. Manganese (7439965) sample results were below the detection limit. The ACGIH threshold limit value for total iron and aluminum particulates is 10mg/m3. Medical questionnaires failed to identify definite work related health problems. The authors conclude that a health hazard did not exist at the time of the survey since all dusts and particulates were under threshold limit values.
