Hazardous exposures associated with refuse derived fuel were investigated in June, 1982 at a steam generation facility which stored and burned the fuel at Wright Patterson Air Force Base in Dayton, Ohio. The evaluation was requested by an unspecified individual. Air samples were collected for determinations of total and respirable particulates, trace metals, organic vapors, polychlorinated biphenyls (PCBs), sulfur-dioxide (7446095), nitrogen- dioxide (10102440), and microbiological agents. In the fuel storage building, concentrations of total and respirable particulates exceeded the respective OSHA limits of 15 and 5 milligrams per cubic meter. Trace amounts of calcium, iron, and manganese also were found. In the fuel burning building, total and respirable particulate concentrations were within OSHA limits, and trace concentrations of calcium, iron, and manganese were found. Concentrations of organics, hydrocarbons, sulfur-dioxide, nitrogen- dioxide, and PCBs were either not detectable or were within acceptable limits. In both buildings, the microbiological agents Klebsiella-pneumoniae, Enterobacter, and Mucor were isolated. The author concludes that workers are exposed to excessive concentrations of total and respirable particulates and to airborne pathogens. He recommends the use of dust suppressing agents, enclosure and ventilation of overhead conveyors, and the use of half mask respirators with dust filters.
