Development of Novel Decontamination Techniques for Chemical Agents (GB, VX, HD) Contaminated Facilities. Phase II. Laboratory Evaluation of Novel Agent Decontamination Concepts
Abstract
Hot gases, steam, FREON, vapor circulation, flashblast, monoethanolamine, ammonia, ammonia/steam, and an aqueous solution of n- octylpyridinium 4-aldoxime bromide (OPAB) were experimentally evaluated for their effectiveness in decontaminating HD, GB and VX. Emphasis was placed on the concepts ability to decontaminate these agents spiked onto painted and unpainted mild and stainless steels and unpainted porous materials. The experimental data demonstrated that the hot gas, steam and OPAB concepts were effective decontaminants for each agent/material combination investigated. An engineering/ economic analysis suggested that either hot gas or steam decontamination of field structures contaminated throughout with agent is feasible. Specific applications for OPAB were identified. In terms of cost, the hot gas concept is preferred over the steam concept. Analytical method development activities indicate that HD, GB and VX interact with concrete. The interaction, possibly a chemical reaction, may obviate the need to decontaminate unpainted concrete in the field, especially in the case of the nerve agents GB and VX.
