Chemical Security Analysis Center

Chemical Security Analysis Center

Location: Aberdeen Proving Ground, MD

CSAC - Chemical Security Analysis CenterIn 2006, by Presidential Directive, 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, 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 Aberdeen Proving Ground 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 and initiated 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.

Our Impact

Did You Know?

In January 2014, approximately 10,000 gallons of 4-methylcyclohexane methanol accidentally leaked into the Elk River, affecting hundreds of thousands of West Virginia residents. As part of the DHS response, S&T CSAC worked with the Federal Emergency Management Agency and other federal, state and local responders to evaluate and assess the impact.
