Decontamination Units, Chemical Neutralization, Spray
Definition : Decontamination units that generate and deliver a controlled spray of a decontamination product (typically a strong base decontaminant) for neutralization and physical removal of chemical and biological agents. These devices usually consist of a portable unit that includes a pressurized tank of the decontaminating solution, a mounting bracket, a pressure gauge, and a safety valve; they also include spare parts and tools to facilitate operation and maintenance by the operator. Spray decontamination units may be used with different decontamination solutions; they are frequently intended to deliver a solution of 2% sodium hydroxide dissolved into 70% diethylenetriamine and 28% 2-methoxyethanol (also known as ethylene glycol monomethylether [EGME]), a product known as decontamination solution number 2, DS2. The spray is capable of neutralizing mustard (HD agent), nerve agents such as VX and the G series (e.g., tabun, sarin), and biological agents on surfaces of vehicles and outdoor equipment). The units should be filled and operated by users wearing appropriate protective clothing.
