CHDS State/Local / The current trend in terrorist tactics is the use of simple, inexpensive and conventional weapons. One such weapon is improvised incendiary devices (IIDs). The homeland security community has underestimated the magnitude of the threat. Policy makers must recognize the potential for terrorist cells to use IIDs to create terror and fear in the public. IIDs have the potential to create devastating fires resulting in mass casualties. In addition to evaluating the risk of an IID attack and determining the state of preparedness of first responders, this thesis includes a proposal for the creation of two new national planning scenarios, urban and wildland conflagrations or firestorms. Recommendations will include incendiary protocols in the weapon of mass destruction matrix as represented by "I" in CBIRNE. This organizational change can be applied to the homeland security strategies, lexicons and documents of Federal, State, and local governments and the private sector to address the IID threat. This thesis is intended to serve as a catalyst for the Department of Homeland Security to set policy that will decrease vulnerabilities and consequences of this lesser-known threat. / Battalion Chief, New York City Fire Department (FDNY)
