• First responders9/11: Twenty Years Later, Responders Still Paying a Heavy Price

    More than 91,000 responders were exposed to a range of hazards during recovery and clean-up operations, with 80,785 enrolling in the World Trade Center Health Program (WTCHP) set up after the attacks. 3,439 are now dead – far more than the 412 who died on the day of the attacks – and many of those alive have been suffering from a series of ailments related to the work at the Twin Towers site.

  • Cyanide detectionKeeping First Responders Safe by Detecting Cyanide Poisoning after Fires

    When first responders rush to a burning building to subdue the fire and save lives, it is not just the flames that are dangerous and potentially lethal, but also toxic fumes like cyanide that are released when certain materials are incinerated. These fumes, mixed with smoke, are so toxic that even in very low quantities may pose more risk than the fire itself. Chemists at DHS S&T have invented a test to indicate possible toxic cyanide exposure at the fire scene.

  • WildfiresDOD Imagery Information Aids Wildland Firefighters

    With continuing significant fire activity in the western United States this year, the Department of Defense (DoD) is delivering requested personnel, equipment, and facilities, to assist our Federal, State, and local partners fighting wildland fires. One of the tools provided by the DoD is the Firefly system pilot program (Firefly), a capability from the National Geospatial-Intelligence Agency (NGA). 

  • Search & rescueAutonomous Drones Could Speed Up Search and Rescue after Flash Floods, Hurricanes and Other Disasters

    By Vijayan Asari

    Rescuers already use drones in some cases, but most require individual pilots who fly the unmanned aircraft by remote control. That limits how quickly rescuers can view an entire affected area, and it can delay aid from reaching victims. Autonomous drones could cover more ground faster, especially if they could identify people in need and notify rescue teams.

  • ResilienceSmall Towns Should Focus on Resilience

    With heatwaves, bushfires, and floods, small towns and their surrounding communities have confronted a combination of successive disasters fueled by climate change. And it’s predicted to only get worse. “So, the challenge for all of us, but particularly areas at increasing risk of climate-fueled disasters, is to get ahead of what’s coming,” says one expert. “We need to ask: what we can do to reduce or even prevent some of these disasters from happening?”

    To the dangerous conditions such as scorching temperatures, drought across 90 percent of the West, and intense wildfire, we must now add another: a looming crisis of burnout among wildland firefighters.

  • Search & rescueCompact Lifesaving Drone for Beach Rescue Teams

    A student designs compact lifesaving drone for beach rescue teams after witnessing teenage surfer battle dangerous waves. As part of his final year project, the student designed a small, compact drone that flies above hazardous waters to locate individuals in distress and deploys a buoyancy aid that automatically inflates when hitting the water, helping casualties stay afloat while they wait for a rescue team to reach them.

  • FirefightersProtecting Lives on the Wildland Fire Line

    Unlike first responders who fight structural fires, wildland firefighters are unable to use the current standard respirator systems, which are heavy, limited to 45 minutes of air and are too bulky. Since the current standard equipment for respiratory protection is a bandanna, DHS S&T and partners designed the Wildfire Respirator around a lightweight mask covering just the mouth and nose, relying on filtration rather than on heavy tanks of compressed air.

  • WildfiresMassive California Blaze Triggers Lightning Fears

    Smoke columns from fires in California could spawn lightning storms that cause more blazes, experts warn. Several communities have been evacuated. Fires in California have already destroyed three times more vegetation this year than they had at this time last year, which was the worst in the state’s history.

    DHS S&T, along with other government agencies, is working on the design and creation of the “H2Rescue” emergency vehicle. The H2Rescue is an innovative new truck that can be a lifeline to responders and community members during times of chaos and uncertainty because the H2Rescue is fully powered by a hydrogen fuel cell.
