> ...there was an ongoing debate about the proper response... I don't know about subway specifics, but the matter was settled a long time ago for buildings - and it didn't take long to arrive at the conclusion. Containment is the policy. The first thing that happens when any toxic substance is suspected, in a security conscious facility, is the shutdown of HVAC followed by the restriction of uncontrolled movement (elevators sent home, security posted in stairwell, etc). Even in areas equipped with filtration systems (like mail rooms). I've never heard anyone suggest dilution, you'd have to have NBC sensors that can instantly detect every toxic substance in order to avoid unknowingly spreading anthrax piggybacked on an irritant like CS. Such sensors do not exist. |
