Abstract : The manufacture, handling, and loading of explosives at Army ammunition plants contaminates process equipment (such as pumps, tanks, and piping) with explosive residue. This residual contamination prevents the maintenance and repair of the equipment as well as its reuse or disposal as scrap. This contamination must be removed before any of this can be accomplished. In addition, many metal munition items, such as projectiles and mine casings, from which explosives have been removed (washout, meltout, or augered out) require additional decontamination (to "5X" standards) in order to dispose of them properly. Previous pilot tests and studies completed by Weston in 1990 (1), have shown that metal components can be decontaminated by heating the items with a circulating hot gas, which volatilizes the explosives and destroys them in a high temperature thermal oxidizer. These tests indicated that metal items contaminated with TNT and treated for six hours at a minimum temperature of 500F are not characteristically hazardous and are appropriate for disposal or, potentially, for resale as scrap. pg9.
