First Measurement Using COUNTERFOG Device: Chemical Warfare Agent Scenario
Nowadays, the threat of a terrorist attack with CBRNE (chemical, biological, radiological, nuclear, and explosive) agents is very real, as can be seen in the increasing appearance of news related to the use of CWA (chemical warfare agent) in criminal acts. In light of these new threats, there are no countermeasures available that can respond quickly and automatically to mitigate the consequences. Therefore, the need arises to develop new countermeasure systems that will act against CBRNE agents.
In this context, the COUNTERFOG project is proposed as a countermeasure system based on the generation of a fog interacting and counteracting the effects of a dispersion of CBRNE in large public buildings. To increase the effectiveness of the system, depending on the agent, different additives are combined with fog. Additionally, the work presented considers the use of metal oxide nanoparticles and its effect on cleaning an atmosphere contaminated with a CWA surrogates. The COUNTERFOG system helps the subsequent physical deposition of the nanoparticles with the contaminant adsorbed. To assess the influence of the fog and of the nanoparticles, a comprehensive experimental procedure has been developed.
