In-depth survey report: control technology assessment of hazardous waste disposal operation in chemical manufacturing, 3M Company, Chemolite Incinerator, Cottage Grove, Minnesota.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, ECTB 103-11b, 1984 Jan; :1-49
Environmental and breathing zone samples were analyzed for organic solvents and total hydrocarbons at the Chemolite incinerator at 3M Company (SIC-2800), Cottage Grove, Minnesota in September 1982. Engineering controls in the pump room and on the drum feed system were investigated. Concentrations of all solvents and total hydrocarbons were below all relevant standards or the limits of detection. General and local exhaust ventilation were used to suppress air contaminant concentrations in the pump room. The ventilation system supplied fresh air at the rate of 15 room changes per hour. General dilution ventilation was the primary control on the drum feed system. A carbon-dioxide injection system and overhead vent were used to minimize potential fire and explosion hazards. Grounding devices were installed on liquid waste feed lines to prevent the occurrence of sparks caused by flowing liquids. Hard hats, safety glasses, company provided uniforms, and safety shoes were routinely worn at the incineration site. Rubber suits, face shields, and half face respirators were worn when corrosive materials were handled. The company had intensive training and education programs. Only minor injuries occurred during the 11 year history of the facility.
