Development of Novel Decontamination and Inerting Techniques for Explosive Contaminated Facilities, Laboratory Evaluation of Concepts. Phase II. Laboratory Evaluation of Novel Explosives Decontamination Concepts

Study experimentally evaluated concepts, identified, evaluated, and recommended in a previous phase, for decontamination of explosive contaminated buildings. Five concepts were first submitted to laboratory scale screening studies. The successful operating conditions so identified were then further evaluated in bench scale studies using 5-inch x 5-inch coupons of typical building materials, both in a painted and unpainted condition. An engineering and economic analysis was then performed on the three concepts (Hot Gas, NaOH/ DMSO Reduction, and combined Hot Gas/Chemical) so demonstrated to be effective. Remaining knowledge gaps pertaining to the implementation of these concepts were then identified and methods for resolving them delineated in a Field Test Plan.
