Science and Technology First Responders

First Responders

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 Science and Technology Directorate (S&T) works closely with first responders across jurisdictions and disciplines to improve their safety and effectiveness.First Responders use a medical skid to evacuate a passenger on passenger from the metro.

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.

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.

Current Projects and Programs

Available Technologies

S&T maintains a growing list of transitioned technologies that were all imagined and field-tested by first responders across the country and are now available for agencies and other members of the Homeland Security Enterprise to procure.
