Health Hazard Evaluation Report No. HETA 81-388-1129, Santa Cruz Metropolitan Transit District, Santa Cruz, California

摘要

On August 19-20, 1981, environmental and medical surveys were conducted during diesel and gasoline bus servicing. Based on the environmental air samples collected during the dates of the survey, overexposure to CO, CO2, SO2, NO2, and total particulate did not exist. However, significant short-term exposures to formaldehyde were measured depending on workers job task, the time of the shift, and the mechanical condition of the bus. The symptoms reported and/or experienced by the workers are generally consistant with formaldehhde exposure and diesel fume exposure.
