Integrating dispersion modelling and experimental approach to optimize indoor/outdoor detection of airborne agents
Mimicking the exposure of an infrastructure
The overarching objective of the ERNCIP “Detection of Indoor Airborne Chemical & Biological Agents” Thematic Group (TG) is to strengthen resilience of critical infrastructure against airborne CB threats by improvement of detection capabilities. The subsidiary aim of the research described in this technical report is to develop knowledge on the behaviour of chemical releases, given some likely attack scenarios, and to propose ways to optimally detect those inside buildings. Making use of a combined approach consisting of experiments and dispersion modelling is considered a strong endeavour towards this aim.
To provide input for dispersion model development a series of medium-scale experiments with representative simulant chemical has been designed. The study made use of controlled release of simulant chemicals in an ambient breeze tunnel (AMB). In the AMB a mock-up of a simple building was installed (scale 1:5). The experiments involved three mimicked attack scenarios: i) focal release from within the mimicked building and external release of agent approaching the mock-up from the outside from a ii) short and iii) a larger distance. Tri-ethylphosphate (TEP) was selected as simulant (for nerve gases). The detector used was an ion mobility spectrometry (IMS) instrument.
