7-912 - Weapons of Mass Destruction (WMD)

Purpose

The purpose of this policy is to outline the necessary awareness of the possible presence of weapons of mass destruction (WMD) or WMD Threat during any emergency. WMDs can include Chemical Weapons, Biological Weapons, Radiological Weapons, Explosive/Incendiary Weapons, and nuclear materials.

Policy

Weapons of Mass Destruction (WMD) pose a great threat to first responders and requires a unique and extraordinary police response. Often times, officers may not know that they are responding to such an incident when dispatched. Members should be aware of signs and symptoms of any victims and should be mindful that any emergency could involve a weapon of mass destruction, particularly unknown trouble, explosions or medical emergencies. It is imperative that the responding member solicit as much information as possible from MECC and/or victims and witnesses in order to properly ascertain whether the call may involve WMD materials.
