Chemical Security Analysis Center

Chemical Security Analysis Center

Location: Aberdeen Proving Ground, MD

CSAC - Chemical Security Analysis CenterIn 2006, by Presidential Directive, the Department of Homeland Security (DHS) established the Chemical Security Analysis Center (CSAC) to identify and assess chemical threats and vulnerabilities in the United States and develop the best responses to potential chemical hazards. Overseen by the DHS Science and Technology Directorate (S&T), CSAC supports the homeland security community by providing a crucial knowledge repository of chemical threat information, design and execution of laboratory and field tests, and a science-based threat and risk analysis capability, among other services. CSAC’s presence on the Edgewood Area of U.S. Army Aberdeen Proving Ground, Maryland allows close collaboration with Army scientists and engineers.

Offering Technical Assistance Capabilities in Response to Investigations and Crises

For inquiries related to chemical threats and chemical hazards, the CSAC offers a 24-hour, seven-days-a-week informational response capability, known as “CSAC Technical Assistance,” to federal, state, local, territorial, and first responder agencies. CSAC Technical Assistance is a key resource for the National Operations Center. CSAC Technical Assistance typically responds to 70 to 80 requests per year. Key customers include the Department of Health and Human Services, Environmental Protection Agency, Federal Bureau of Investigation and many other agencies and industry stakeholders.

Project Jack Rabbit—Helping DHS and its Partners Reduce the Risk of Large-Scale Toxic Inhalation Hazard Chemical Releases

Each year, hundreds of millions of tons of chemicals like chlorine and ammonia are transported through U.S. population centers. Although these chemicals are essential, they are toxic and pose a risk to the public through accidental release or an act of terrorism. To better understand and address this risk, CSAC conducted Project Jack Rabbit in 2010 followed by the Jack Rabbit II (JR II) program in 2015-2016.

Jack Rabbit I involved a series of 1- to 2-ton outdoor chlorine and ammonia release trials involving a team of stakeholders from government, industry, and academia.

Scientist testing chemicalsJack Rabbit II continued where Jack Rabbit I left off, with release trials of up to 20 tons. These experiments were unprecedented and filled crucial knowledge and data gaps. Prior to Jack Rabbit I and II, large-scale chlorine releases had never been tested at volumes representative of rail cars, tanker trucks, barges or bulk storage tanks. Jack Rabbit improved hazard prediction modeling, emergency planning, and response and mitigation strategies, as well as the United States' resilience against chemical release incidents.

The final test reports of S&T CSAC’s Jack Rabbit I and II Programs have been approved for public release. The JR II Program Final Test Report documents the large-scale outdoor chlorine release trials conducted at U.S. Army Dugway Proving Ground, Utah, made possible by direct support from the U.S. Defense Threat Reduction Agency, Transport Canada, and Defence Research and Development Canada.

Jack Rabbit III, a continuum endeavor, will consist of laboratory, chamber, and field experiments to gather scientific data and identify technologies to fill critical data gaps. The Jack Rabbit III focus is to build security, safety, and resilience in the chemical supply chain through experimentation over the next five years. Jack Rabbit III involves the work of a collaborative team of partners and cosponsors from government, industry, and academia to identify and prioritize critical data gaps for toxic inhalation hazard (TIH) chemical release atmospheric dispersion modeling; emergency preparedness and response; and hazard and risk mitigation procedures.

Our Impact

Did You Know?

In 2019, S&T CSAC responded to a DHS National Operations Center (NOC) request for information regarding Hurricane Dorian to provide critical chemical facility information and analysis of the toxic chemical hazards and risks within the potential hurricane effect zones. Hurricanes pose a significant risk to even the most secure chemical facilities, with storm-driven power outages, high winds, and flooding potentially leading to chemical leaks, explosions, or fires. S&T CSAC analysis documented the chemical type and the amount being stored at more than 2,000 chem­ical facilities in the southeastern United States, Puerto Rico, and the Bahamas.
