The objective of this study is to provide a hypothetical scenario of indoor dispersion of the highly toxic nerve agent sarin in a large building, which can be used as a starting point for discussion, planning, training and exercises for emergency services and responsible authorities. The indoor dispersion has been simulated using a Computational Fluid Dynamics (CFD) approach. Possible consequences have been calculated based on concentration and dose profiles. Mild intoxication effects appear within minutes, while serious injuries and fatalities occur approximately 20 min after release. Anticipated key emergency response challenges are: (i) the time factor due to rapid onset of symptoms, (ii) the large number of casualties, and (iii) the contaminated hazard scene.
