Chemical Consequence and Threat Desktop Tool Fact Sheet


The Homeland Security Presidential Directive-22 (HSPD-22), Domestic Chemical Defense, requires an analysis of Chemical Terrorism as a critical element of the nation’s domestic chemical defense policy. The Department of Homeland Security Science and Technology Directorate Chemical Security Analysis Center (CSAC) developed a suite of models to identify, assess and prioritize the threat, vulnerability and consequences of a chemical attack against the U.S. homeland. As part of this program, the consequence and medical mitigation modules have been incorporated into a fast-running classified desktop tool (The Tool), which allows the user to evaluate the severity of an event and the impact of various response and mitigation strategies.
