In response to a request from the management of the Municipal Power Facility (SIC-4931), Ames, Iowa and the International Union of Electrical Workers Local 234, an evaluation was made of possible health hazards at this work site. Concerns were specifically expressed about the handling and burning of refuse derived fuel (RDF), asbestos (1332214) insulation, coal dust, fly ash, hot working environments, polychlorinated-biphenyl (1336363) (PCB) present in grounding transformers, and on site chemical usage and storage. RDF was composed primarily of the shredded combustible part of municipal solid waste. A survey of the facility indicated that potential hazards did exist from noise, heat, asbestos, coal dust, and crystalline silica (14808607). The only documented case of over exposure was to coal dust in the coal yard. Metal exposure was very low or non detectable. The author concludes that hazards existed due to heat levels, noise, potential asbestos exposure, and elevated coal dust and silica exposures. The author recommends work schedule modifications to reduce heat stress, improved storage methods for chemicals, improvements in the respiratory protection program, a hearing conservation program, monitoring workers for trace metal exposures, asbestos cleanup or monitoring, employee education regarding possible hazards, and medical surveillance.
