Fast Response CBRN High-Scale Decontamination System: COUNTERFOG
COUNTERFOG is a new, rapid response system for collapsing all kinds of dispersed agents (smoke, fog, spores, etc.) by using a fog made of a solution that could eventually contain any kind of neutralizing component. It will be a permanent installation in large public buildings like railway stations or critical infrastructure but also a portable COUNTERFOG for use outdoors, used to counteract a CBRN attack in its earliest stages, greatly reducing the number of potential fatalities. In fact, COUNTERFOG uses the same “weapon” as a CBRN attack: a dispersed state with a large surface/volume ratio. Under certain conditions, it can penetrate all the intricate holes CBRN agents are able to infiltrate. As it needs a minimum quantity of decontaminant, it is intrinsically an environment-friendly and electric-compatible system. It has several benefits: firstly, to neutralize and collapse the CBRN cloud quickly limiting its extension and, secondly, to rapidly decontaminate all the affected area and any equipment. Prototypes have been developed and tested with agent surrogates in a specifically developed Fog Dynamics Laboratory. The results show that COUNTERFOG is effective against chemical, biological, and radiological surrogates and has a potential to be used both to counteract and to decontaminate. This work has been funded by FP7-SEC-2012-1 program of the EU Commission under grant number 312804.
