Health Hazard Evaluation Report HETA 83-198-1646, U.S. Army Corps of Engineers Supply Depot, Kansas City, Missouri
Environmental surveys were conducted at the U.S. Army Corps of Engineers Supply Depot during a re-roofing operation (SIC-1761) on March 28, April 18 and 19, 1983. The U.S. Army Corps of Engineers, Kansas City District had requested the evaluation of working conditions and recommendations for reducing occupational exposures. Personal air samples for acetonitrile solubles were collected on all seven workers involved with tear off, repair of roof deck, and application of an asphalt (8052424) built up roof. The acetonitrile soluble portion was used as an indicator of exposure to asphalt fumes. Values for personal samples ranged from .04 to .83 milligrams per cubic meter (mg/m3). NIOSH and the American Conference of Governmental Industrial Hygienists recommend a time weighted average (TWA) exposure limit of 5.0mg/m3 for asphalt fumes. Area air samples ranged from 0.02 to 3.0mg/m3, with six of the values less than or equal to 0.40mg/m3. Individual polynuclear aromatic hydrocarbons from area air samples were less than the 250 nanogram per sample limit of detection. The author concluded that workers were not over exposed to asphalt fumes. Recommendations to further reduce exposures at other sites include the scheduling of work to reduce the number of employees exposed, locating the kettle and work areas to reduce exposure to fumes, and keeping the temperature of the kettle at an absolute minimum necessary to meet material specifications.
