Strategy to optimise building ventilation to aid rescue of hostages held by terrorists.

One strategy to secure the release of hostages held by terrorists, is to release an anaesthetic agent through the ventilation system. But it is not so easy to apply. The demand concerning the right amount of anaesthetic needed must be analyzed, along with the specific place in the building where it is required. A model has been made formulated to find the most appropriate strategy for this kind of emergency ventilation. The results are presented and recommendations given for applying the model in practice.
