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.
本研究的目的是提供一个在大型建筑物中高度有毒神经毒剂沙林的室内扩散的假设情景，可作为紧急服务和主管部门讨论、规划、培训和演习的起点。室内扩散已使用计算流体动力学（CFD）方法进行模拟。根据浓度和剂量分布计算了可能的后果。轻度中毒效应在数分钟内出现，而严重伤害和死亡则在释放后约 20 分钟发生。预计关键的紧急应对挑战是：（i）由于症状迅速出现而导致的时间因素，（ii）大量伤亡，以及（iii）受污染的危险现场。
