To effectively support the Department of Homeland Security (DHS) mission, the DHS Science and Technology Directorate’s (S&T) Chemical Security Analysis Center (CSAC) must address complex and increasing chemical threats that require lab experimentation. DHS and its operational components rely on critical data, modeling, simulation, and guidance produced by CSAC to inform their planning and response operations. In 2022, CSAC stood up its Chemical Security Lab (CSL) as a new capability for experimental analysis of chemicals and hazardous substances. The facility is proximate to CSAC’s main building located in Edgewood at the Aberdeen Proving Ground in Maryland.
As part of DHS S&T, CSAC is the nation’s only federal study, analysis and knowledge management center for assessing the threat and hazard(s) associated with an accidental or intentional large-scale chemical event or chemical terrorism event in the United States.
DHS S&T released an RFI encouraging chemical and biological defense companies to bring their innovative technologies for test and evaluation in the Chemical and Biological Advanced Capability Testbed (CBT) in the New York City Subway system.
This report summarizes the procedures for taking experimental data (chlorine gas concentration time histories) and determining model parameters which can be used directly in atmospheric dispersion models to determine the initial rate of deposition (removal by reaction) of chlorine on typical environmental surfaces.
Using science-based chemical threat and hazard analysis, S&T stands ready to assist emergency planning, preparedness, and response efforts.
DHS S&T announced that it will join several New York City agencies for an above- and below-ground air sampling study that will ultimately help urban areas prepare for and recover from incidents involving hazardous materials.

S&T CSAC developed a new cyanide detection test method, both affordable and efficient, to test fire survivors for toxic cyanide exposure at the scene.
S&T’s research and development support prevention and protective strategies, as well as the coordinated surveillance and detection of chemical, biological and explosive threats.
S&T is studying how anhydrous ammonia behaves during a potential leak or spill, whether accidental or intentional, in order to inform planning efforts in communities across the nation.
