Selected Occupational Health Hazard Controls In The Incineration Of Hazardous Wastes.
NIOSH 1984 Sep:80 pages
Surveys of control technology in the hazardous waste incineration industry (SIC-4953) were conducted. Twelve walkthrough and four in depth surveys were conducted. State of the art engineering controls existed at three facilities. At these facilities, liquid wastes in 55 gallon drums were dumped automatically into hoppers enclosed within ventilated booths. Bulk liquids received in tank trailers or 600 gallon dumpsters were connected by electrically grounded transfer hoses to the furnace or to storage tanks. The trailers were vented to spot (local) scrubbing systems, and explosive proof pumps were used. Solids, sludges, and sample bottles were handled by an automated pack and drum feed system or by a loader. General ventilation, 12 to 15 changes per hour, was provided. The facilities provided employee training in health hazards and safety. Good work practices such as using appropriate personal protective equipment and safety belts and chutes around kiln openings were observed. Concentrations of low to medium toxicity materials were between 1 and 15 percent of their threshold limit values. The author notes that at some facilities, respiratory protection was used as an added precaution when handling highly toxic wastes, although the engineering controls alone were sufficient to meet the exposure standard.
