ST-Questions to Ask When Researching Counter Unmanned Aircraft Systems

This list of questions was created by DHS S&T’s National Urban Security Technology Laboratory (NUSTL) to help Department of Homeland Security Components, and other entities with C-UAS authority build a comprehensive understanding of the nuances, capabilities and limitations of C-UAS technology to aid in purchasing decisions.

S&T Radio Frequency Detection, Spectrum Analysis, and Direction Finding Equipment

Radio frequency detection, spectrum analysis, and direction finding equipment detect, identify and analyze radio frequency signals from radios, cellular devices, GPS, Wi-Fi, and other emitting devices. These devices can be used to identify transmissions from suspicious or threatening sources, including interference that may be blocking or damaging first responder communications.

S&T Small Unmanned Aircraft Systems for Search and Rescue (FRROST)

Small unmanned aircraft systems (sUAS)—systems whose gross take-off weight is less than 55 pounds—offer tremendous potential for emergency responders supporting public safety missions, allowing responders to carry out missions at a fraction of the cost of a manned aerial response, while keeping them out of personal danger. These systems also offer opportunities to perform missions impossible for manned vehicles, such as exploring the inside of buildings or tunnels.

S&T Non-AEL SAVER Projects

The purpose of the SAVER Program is to assist responders with procurement decisions. To this end, SAVER Program knowledge products focus on equipment that falls within the categories of the Federal Emergency Management Agency’s (FEMA’s) Authorized Equipment List (AEL)—a list of approved equipment types allowed under FEMA’s preparedness grant programs. While the FEMA AEL encompasses a wide range of equipment types, it does not include all types of equipment used by responders in the commission of their duties.

S&T Less Lethal Technologies for Law Enforcement

Less lethal technology devices are designed to be less likely to cause death when deployed than conventional weapons like firearms, and are used by law enforcement in two primary situations: crowd control and one-on-one suspect apprehension. For each of these situations, technology subcategories exist based on the modalities of the technology, such as chemical, kinetic and conducted energy.

S&T Respiratory Protection for Firefighters during Overhaul Operations: Operational Field Assessment Report

After extinguishing structural fires, firefighters carry out fire overhaul operations to locate and extinguish smoldering hot spots. Early on in the overhaul operations, firefighters wear self-contained breathing apparatus (SCBA); although, it is common practice to remove the SCBA when the carbon monoxide (CO) concentration drops to a safe level. Studies have shown, however, that after CO dissipates, particulate matter and harmful chemicals are still present during overhaul environments. As a result, firefighters must continue to wear heavy SCBA equipment throughout overhaul operations or risk breathing in the hazardous material present in the overhaul environment. To address this hazard, the Respiratory Protection for Firefighters during Overhaul Operations project developed a filter module that is designed to be used in passive air-purifying respirators (APRs) and powered APRs (PAPRs) to protect firefighters from particulate and chemical hazards while being lighter and more comfortable than the traditional SCBA.
