  • Firefighters mull using drones in fighting wildfires

    Federal wildland firefighting officials are exploring the deployment of drones to assist in surveillance and reconnaissance missions during a wildfire. Drones sent to survey fire patterns during a wildfire could help keep firefighters out of risky situations by providing real-time information to officials on the ground. Few wildfire officials have used drones in the line of duty, and managers with the U.S. Bureau of Land Management(BLM) and U.S. Forest Servicesay that while the technology has potential, agencies do not have the budget and have not developed protocols to integrate drones into regular firefighting operations.

  • Iowa to allow public release of information about trains carrying crude

    Iowa officials have announced that they will alert the public about trains carrying one million gallons or more of “extra-flammable” crude oil throughout the state — despite the argument of railroad companies that the information could pose a security threat. Iowa’s decision places the state in the spotlight as a possible model for how the rulings will proceed in the rest of the country.

  • Hazardous devices teams to compete at Robot Rodeo

    Hazardous devices teams from around the Southwest will wrangle their bomb squad robots at the eighth annual Robot Rodeo beginning Tuesday, 24 June at Los Alamos National Laboratory.

  • Inexpensive seismic alert device may help Mexico City residents

    Mexico City has been experiencing an unusually large number of tremors within the past few months, and though the country has one of the most advanced seismic alert systems in the world, many residents are unable to receive notifications before tremors occur. Mexican regulations limit the sale of government-issued earthquake alert receivers to one private company, but since the receivers cost an average of $310, most families are unable to afford them. Andres Meira, a 39-year-old architect, has designed an earthquake alert receiver, which costs only $54 at retail, which taps into the government’s earthquake alert frequency to notify its users of a pending earthquake.

  • Close air support technology helps in fire suppression

    In the heat of battle, lives can depend on being able to coordinate troop positions safely while directing aircraft to provide close air support for ground forces. DARPA’s Persistent Close Air Support (PCAS) program aims to help overcome those challenges by providing soldiers with advanced digital tools for situational awareness and targeting in place of legacy communications systems and traditional paper maps. Firefighters battling wildfires face challenges very similar to those that troops face in battle — the need for situational awareness, precise coordination of airborne water drops and ensuring fellow firefighters are kept safe from rapidly moving and shifting flames. Technology developed for air-to-ground warfare has been adapted to help firefighters combat deadly forest blazes.

  • Free app alerts CPR-trained individuals to a heart attack case in their immediate vicinity

    Speed and timeliness is instrumental to saving the life of a victim of cardiac arrest, so Santa Clara Countyagencies have adopted PulsePoint, a free mobile application (app) which uses location-based technology to alert CPR-trained residents and bystanders if someone in their immediate area is experiencing sudden cardiac arrest. Once alerted, residents can decide whether they are available to reach the victim and begin resuscitation until official emergency responders arrive.

  • New generation of aerial robots for high-risk missions

    The need for robots able to carry out high-risk service tasks, such as the inspection of power plants and the cleaning of skyscrapers, is growing. Robots which actively interact with the environment without being constrained on the ground are well suited to such tasks.

  • Feds, rail operators, Washington State embroiled in crude oil shipment disclosure dispute

    Last month the U.S. Department of Transportation(DOT) ordered rail carriers with trains carrying crude oil to notify state officials in the states through which the trains pass about the volume, schedule, and routes of these trains. The amount of crude oil transported by trains has grown dramatically – from 6,000 carloads in 2005 to more than 400,000 carloads in 2013. The increase in the volume of crude oil shipping has been accompanied by a sharp rise in the number of accidents and derailments. DOT’s order was meant to allow states’ first responders to be prepared, but the railways treat shipping information as “security sensitive” and refuse to share it with states’ officials unless the information is distributed to emergency response groups for planning purposes only. Washington State says that state laws require that such information be made public.

  • All-natural mixture offers promising fire retardant

    What sounds like fixings for a wizard’s potion — a dash of clay, a dab of fiber from crab shells, and a dollop of DNA— actually are the ingredients of promising green fire retardants invented by NIST researchers. Applied to polyurethane foam, the bio-based coatings greatly reduced the flammability of the common furniture padding after it was exposed to an open flame. Peak and average rates of heat release — two key indicators of the magnitude of a fire hazard — were reduced by 48 percent and 77 percent.

  • Rio builds a high tech integrated urban command center

    Rio de Janeiro is one of the most densely populated cities in South America. Much of the city is vulnerable to flooding, and about three-quarters of Rio’s districts have areas at risk of landslides. High temperatures can make living situations unbearable. In addition, a high crime rate and poor infrastructure make the city difficult to govern. In preparation for the 2014 World Cup and 2016 Summer Olympics, authorities are looking to improve response times to disasters and establish a more efficient system to deal with the city’s many challenges. One of the solutions is a high tech integrated urban command center — Centro de Operações Preifetura do Rio de Janeiro (COR) – which unites Rio’s thirty departments and some private suppliers in a single monitoring room where operators can track real-time conditions of the city and coordinate a response to emergencies and disruptions.

  • Nature-inspired designs for drones of the future

    Based on the mechanisms adopted by birds, bats, insects, and snakes, fourteen research teams have developed solutions to some of the common problems that drones could be faced with when navigating through an urban environment and performing novel tasks for the benefit of society. Whether this is avoiding obstacles, picking up and delivering items, or improving the take-off and landing on tricky surfaces, it is hoped the solutions can lead to the deployment of drones in complex urban environments in a number of different ways, from military surveillance and search and rescue efforts to flying camera phones and reliable courier services.

  • Texas cities adopt 911 texting

    Adding to the rising number of U.S. cities that accept 911 emergency texts, North Texas public safety agencies will now institute the procedure at their response centers. 911 emergency texting not only helps the deaf, but it better caters to younger generations that do not recognize as much the divide between text and voice communications. The texting of additional media such as photos before the responders reach the site could also have a profound impact on the development of an emergency situation.

  • Colorado tries to increase safety of urban development in wildfire-prone areas

    Colorado continues to deal with the challenge of building new urban developments while reducing wildfire risks. There are currently 556,000 houses built in burn zones around the state, and the demand for water to sustain residents and industries continue to rise. A new study predicts that development will occupy 2.1 million acres in wildfire-prone forests by 2030, an increase from one million acres today — just as wildfires continue to burn roughly 900,000 acres a year since 2000, compared with just 200,000 acres a year in the 1990s.

  • Pandemics: who should be given life-saving treatment first? Who should make the decision?

    In the event of a flu pandemic, who should have priority access to life-saving ventilators, and who should make that determination? Few disaster preparedness plans have taken community values regarding allocation into account, but a new study is aiming to change that through public engagement with Maryland residents. “In the event of a healthcare crisis, understanding the community perspective and having citizen buy-in will be critical to avoid compounding the initial disaster with further social upheaval,” says the principal investigator.

  • Improving gloves to enhance first responders’ safety

    Firefighters wear protective gloves called “structure gloves” to keep their hands safe on the job. The structure gloves currently used by firefighters, however, are not designed for the precision movements first responders must perform. There are many different types of structure gloves available, but none fully satisfies modern firefighters’ needs. Today’s compact tools often have small buttons that require nimble movements. Bulky gloves can make it difficult for firefighters to complete simple tasks without removing their gloves and compromising their safety. As advanced textile technology and materials continue to develop, the science behind firefighter structure gloves has adapted.
