First Responder Technologies

First responders are often the primary line of defense for U.S. communities, responding to an evolving spectrum of natural and man-made threats. The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) works closely with first responders across jurisdictions and disciplines to improve their safety and effectiveness.

S&T First Responders. Using science to strengthen first responders and the nation. 18,000+ Improved firefighter garments. 1.25 million threats detected. 2,000+ state and local law enforcement officers trained to detect radiation. Helping law enforcement seize more than $10 million in criminal funds. Industry sold over 40,000 products developed by S&T accounting for $19 Million in sales revenue. Supporting over 3 million public safety users with and mobile radio interoperability. 30+ states using our enhanced information sharing tools, technologies, resources & exercises.488+ state and local bomb squads using S&T technology and techniques. 9% improvement in imposter detection through innovative training technology. Helping safe 475 child sex trafficking victims. 21 state and terrirtories using hurricane evacuation tool.

S&T works hand-in-hand with members of all first responder disciplines—law enforcement, fire services, emergency medical services and emergency management officials, as well as innovators and industry—to develop capabilities that:

  • Make first responders safer
  • Improve communication tool security and effectiveness
  • Enhance data and information sharing during daily, emergency or joint operations
  • Promote and sustain partnerships with responders and responder organizations across the nation at all levels
  • Help investigate cybercrime and cases involving digital evidence
  • Secure 911 emergency call systems from cyberattacks

S&T holistically examines responder technology and capability needs and safety requirements. Starting with first responder uniforms and working outward, S&T helps first responders integrate sensors that monitor their health, location and safety, as well as improve uniforms' protective properties. S&T develops first responder technologies and conducts market surveys and assessments to help responder organizations make informed buying decisions. From ensuring interoperability to improving connectivity and capabilities, S&T’s programs and projects also encompass the communications spectrum.

S&T strives to identify first responder needs, identify existing technology, and work with the development community and industry to provide solutions that improve effectiveness, efficiency and safety. Fire fighter, paramedic, and police officer in front of American flag

No emergency is standard. S&T strengthens first responder capabilities in daily operations and in response to critical incidents and catastrophic events and modern criminal investigations.

National Urban Security Technology Laboratory (NUSTL)

As a federal laboratory organized within DHS S&T, the National Urban Security Technology Laboratory brings together the interests and initiatives of the Homeland Security Enterprise with the first responder community. The laboratory’s mission activities in test and evaluation and research and development help first responders prepare, protect and respond to homeland security threats.
