Abstract:

As a result of evaluating the experience from the chemical terrorist attack in the Tokyo subway, responsible authorities of the City of Prague decided to equip the Prague METRO with a detection and monitoring system to enable early warning and adopting immediate protection and rescue measures in case of possible terrorist attack. After experimental analysis of airflows and other conditions including modeling within the system of underground stations and assessment of available gas alarms to detect the widest possible spectrum of toxic chemicals in consideration to be misused by terrorists with desired detection limit and within the shortest possible response time and their feasibility to be incorporated into a network of remote signal transmission to the central checkpoint the ion-mobility spectrometers were suggested as the most appropriate from the available choice. These monitors started to be introduced since the 1997.
