Rajant and Dejero’s Technology Springs into Action in the Battle Against a 420-Acre Wildfire on the Santa Barbara County Coast. A wind-driven brush fire triggered evacuations after breaking out along the Gaviota Coast in Santa Barbara County, California.

On a sunny afternoon in mid-October 2019, the heat from the sun combined with winds gusting up to 40 mph through the quiet foothills of El Capitán Canyon, sparking a wind-whipped, vegetation brush fire in the overly dry desert hills. The blaze, dubbed the ‘Real Fire,’ quickly charred 420 acres while threatening more than 100 structures that sat along the Gaviota Coast before firefighters and emergency crews were aware of the fire and able to gain an upper hand on the wild blaze.

Wind-Driven bush fire

Coincidentally, Rajant and Dejero had just arrived in Santa Barbara for a demonstration with the Santa Barbara County Fire Department. Shortly after the fire broke out, word reached the emergency services and crews from the Santa Barbara County Fire Department, Cal Fire, the U.S. Forest Service, and other agencies who immediately dispatched their teams to contain the blaze before it spread further.

The climate in the canyon at the time of the blaze was considered ‘critical fire weather’ with its dangerously dry grass and wind gusts. These conditions only encouraged the wind-driven bush fire to spread swiftly through the foothills on the north side of Highway 101 near El Capitán State Beach, California and east over the ridge. A good stretch of the 101 Freeway had to be shut down immediately—in both directions—and Amtrak routes through the area were canceled.

Total communications solution

At the peak of the fire, helicopters and fixed-wing aircrafts attacked the flames from the air with retardant and water drops

Visitors at nearby ranches, campgrounds, beaches, and resorts were evacuated, and a warning was given to residents living in the nearby Dos Pueblos, Refugio, and Winchester Canyons. At the peak of the fire, helicopters and fixed-wing aircrafts attacked the flames from the air with retardant and water drops, while dozens of engines, along with bulldozers and hand-crews, fought it from the ground.

At about that same time the fire broke out, teams from Rajant and Dejero, along with subject matter expert Bruce Arvizu from the Department Homeland Security, had arrived in Santa Barbara. Together, they were prepared to deliver a live safety demo to the Santa Barbara County fire chief on how the companies can together provide the total communications solution.

Improved spectrum efficiency

The planned public safety demo was also to show how the blending of Rajant’s technology with Dejero Smart Blending Technology (SBT) eliminates drops and gaps—a solution comprised of mesh radio communications, blended cellular, and satellite technologies to bridge the communication gap in remote locations where signals are often weak or lost.

While LTE networks provide high bandwidth, lower latency, and improved spectrum efficiency, LTE can also become spotty and drop signals in remote locations and other areas. Dejero’s Smart Blending Technology (SBT) fills in these gaps in the Wide Area Network by seamlessly blending any available LTE with SAT comms to guarantee a connection for the responding teams. Signal continuity becomes even more challenging in valleys, around mountains, and along coastlines, which becomes mission critical when emergency services are responding.

Continuous and reliable connection

More than 200 firefighters were on site fighting the fire with reinforcing containment lines of helicopters

Rajant’s mesh radio technology bridges the gaps in these local areas. When the three technologies are used together, a continuous and reliable connection is provided, ensuring that communications between the responding agencies and their teams in the field are not lost.

Meanwhile at the El Capitán canyon, more than 200 firefighters were on site fighting the fire with reinforcing containment lines of helicopters and drones in the air and 30-ton bulldozers on the ground cutting out ‘catlines’ and uprooting vegetation, thus eliminating the fire’s fuel.

By plowing through the flames, brush, and trees with the dozers, the emergency crews saved valuable manpower and shortened the fire’s reach and life. When fighting fires with bulldozers, it is critical for the commander in control to receive data from each dozer to manage fighting the fire collectively as a team and to track each dozer individually.

Critical local data

Rajant and Dejero quickly proposed to the fire chief the benefits of their combined technology at a time of crisis and asked to allow Rajant and Dejero to modify their presentation from a demo to a real life exercise.

Our county firefighters are willing to do whatever it takes to get that job done. When we do our after-action review, the successes and failures always come out. And we like to capitalize on our successes.” said Daniel Bertucelli, County Fire Captain Santa Barbara County Fire Department. Rajant BreadCrumbs® can be mounted to the bulldozers so the critical local data could be transmitted while other situational data and mapping could be revived in the field. Dejero SBT would power the Microsoft Tactical Truck and provide the bridge from the field to the command post over cellular and SAT networks, during this actual emergency situation.

Combined firefighting attacks

More than 400 acres had burned with no structures damaged and no reported injuries

Notably, the SAT comms on the vehicle was to be powered by Kymeta’s flat-panel dish technology, enabling true ‘comms on the move’ to best leverage Rajant’s Kinetic Mesh®. The updated mission was green lighted. On Friday morning, Rajant and Dejero meet with the fire squad at the command control center.

Rajant BreadCrumbs and camera systems were mounted to dozers while the Microsoft mobile comms truck, with the Dejero GateWay on-board, maintained a close, but safe, proximity to the dozers to provide LTE. The firefighters manning the bulldozers were able to communicate in the valley when normally they could not. Data was sent from the bulldozers to the van to the internet where the command control center could receive the video feed.

The real-life demo was a success. The combined firefighting attacks on the blaze gained the upper hand and went from a 20-percent containment on Thursday evening to 50-percent by Friday afternoon. By Monday, the Real Fire was 100% contained. More than 400 acres had burned with no structures damaged and no reported injuries. Evacuations were lifted for all areas.

In A Busy Wildfire Season, Researchers Seek New Approaches
In A Busy Wildfire Season, Researchers Seek New Approaches

It makes perfect sense that a horrific wildfire season would come in the year 2020 on the heels of a pandemic. Dozens of major fires burned across North America in September, including 85 large uncontained fires and six contained fires across 12 states. Active fires have burned more than 3 million acres already, and 41,417 fires have burned almost 5 million acres year-to-date. The severity of the wildfire season is on track to surpass the 10-year average. Better understanding wildfires Global warming is often mentioned as a contributor to the wildfires, but there are other factors, too. Increasingly, researchers are looking to apply new approaches in address the risk of wildfires. They include tools such as deep learning and artificial intelligence (AI) to better understand wildfires and to control their intensity. The model could be used to reveal areas of greatest risk for wildfires A new deep learning model uses remote sensing and satellite data to trace fuel moisture levels across 12 Western states, in effect tracking the amount of easily burnable plant material and how dry it is. After additional testing is complete, the model could be used to reveal areas of greatest risk for wildfires and to plan the best areas for prescribed burns. Led by a Stanford University ecohydrologist, the research was published in the journal Remote Sensing of Environment. Recurrent neural network The model uses data from the U.S. Forest Service’s National Fuel Moisture Database, which amasses plant water content information from thousands of samples. Using a ‘recurrent neural network,’ the system leverages the fuel moisture data to corroborate measurements of visible light and microwave radar signals from spaceborne sensors that are tasked with estimating fuel moisture measurements. Newer satellites with longer wavelengths allow sensitive observations about moisture content deeper into the forest canopy. Estimates from the model are used to generate interactive maps that fire agencies may one day use to identify patterns and prioritize wildfire control estimates. Researchers are also working to analyze the impact of better and more efficient firefighting on the size and frequency of wildfires. The theory goes: When firefighters extinguish smaller vegetation fires, a consequence is the creation of an environment where wildfires are larger and/or more frequent. Natural cycle of regeneration Older woods will naturally catch fire from the sun’s heat to make way for fresh growth The theory is based on the premise that wildfires play an essential role in the periodic regeneration of forests. Older woods will naturally catch fire from the sun’s heat to make way for fresh growth. However, more efficient firefighting can disrupt the natural cycle and, along with global warming, aggravate the broader likelihood of larger and more frequent fires. Researchers at the WiFire Lab in California and the University of Alberta in Canada are using artificial intelligence (AI) to analyze the environment and provide recommendations for prescribed burns that can save some parts of the forest without interfering with the natural cycle of regeneration. Providing early warning of wildfires Equipment operated by Pacific Gas and Electric (PG&E) caused 2018’s Camp Fire, the most destructive wildfire in California history. Because of the threat of sparking a wildfire, PG&E this year shut off power to 172,000 customers in Northern California on Labor Day weekend, for example. A concern is the threat of winds tearing down power line or hurling debris into them. Southern California Edison (SCE), another utility, warned that about 55,000 customer accounts could lose power. California utilities SCE, PG&E and San Diego Gas and Electric are helping to fund a network of ALERTWildfire video cameras in California that will help to provide early warning of wildfires. Video cameras keep watch throughout five Western United States to provide early warning, and the number of cameras is growing fast.

Should Firefighters And First Responders Use Face Masks?
Should Firefighters And First Responders Use Face Masks?

Should firefighters and other first responders be exempt from requirements that they wear face masks to prevent spread of the novel coronavirus (COVID-19)? The City Council of Portsmouth, New Hampshire, seems to think so. They are proposing an amendment to exempt first responders from complying with the city’s face mask ordinance. Amendment to Exempt first responders from face mask rule Specifically, the proposed amendment states, “Exempted from the requirements of the ordinance requiring wearing of face coverings include law enforcement personnel, first responders or other workers, who are actively engaged in their tasks, if wearing a face covering may hinder their performance.” The Centers for Disease Control and Prevention (CDC) recommends that everyone wear masks in public settings The Centers for Disease Control and Prevention (CDC) recommends that everyone wear masks in public settings, especially when social distancing cannot be maintained. The CDC does not specify a need to exempt first responders. However, there is a possibility that a mask could interfere with the work of firefighters or first responders, especially when they are performing tasks that require physical exertion. Face masks can inhibit communication among first responders Face masks, covering the mouth and nose, could also inhibit communication by muffling sound and obstructing facial expressions. Obviously, communication is of paramount importance for firemen working as a team in an emergency, or when a first responder is seeking to give clear directions to the public. The issue of face masks has been inexorably entwined with the well-being of first responders, since the beginning of the COVID-19 pandemic. Early on during the infection spread, health officials dismissed face masks as a tool to avoid spread of the disease. They said that the masks were ineffective at preventing community spread and that, supplies of personal protective equipment (PPE) needed to be conserved for health professionals and first responders. Importance of face masks in controlling spread of COVID-19 However, the early advice was completely reversed in late March 2020 and masks have been advocated ever since. A mask, worn by an infected individual, reduces the dispersion of virus-laden droplets that spread the disease. Now, experts contend that any type of mask, including cloth or paper, can help to reduce spread of the COVID-19 virus. Expanding the use of masks to include those that are not conformant with the N-95 classification effectively eliminated any concerns about supply and helped to make the widespread use of masks the norm. To some extent, however, mask usage in the United States has been politicized and some see the requirements as an affront to liberty. Need for wearing face masks in public Masks are a useful preventative measure for firefighters working together in a communal area Fire and emergency departments face the same challenges as other businesses and institutions, as they seek to remain safe in a communal workspace. Masks are a useful preventative measure for firefighters working together in a communal area or when training or resting. Wearing masks in public also allows departments to model best practices and promote a positive perception of the department to the public. Disciplined use of face masks demonstrates unselfishness and respect for others. It communicates professionalism and concern for the greater good. Masks go a long way in saving lives of first responders Perception may also be an issue when it comes to the choice of masks, which become a de facto part of a uniform. Masks with political statements should be avoided, for example. Considering that dozens of American fire and EMS members have died of COVID-19 infection, since March 2020, the use of masks is another way that firefighters can work to save lives. However, sufficient flexibility is needed so that the use of masks does not interfere with other lifesaving duties.
