Working in the fire service for 30 years has allowed me the privilege of watching it grow and modernize. With growth comes greater responsibility. Today’s fire service is equipped to deal with man-made and natural disasters because of better training, equipment, and tools.
Thermal imaging is one of the modern tools of the fire service that still needs to be fully embraced by firefighters. You don’t need a thermal imaging camera (TIC) to fight a fire, but using a TIC could increase safety, efficiency, and effectiveness.
Firefighter safety is the first and most critical benefit of using a TIC. Becoming lost or disoriented inside a burning structure can be a harrowing experience. The TIC can help. The primary cause of firefighter disorientation is the lack of visibility. Without smoke, navigating a building is a pretty easy task. Now, add thick, black smoke, and the task is difficult. This is where the TIC can be the most helpful. A TIC gives you the ability to see the orientation of the structure, including specific rooms and furnishings, allowing for safer maneuvering. Secondary means of egress are easy to locate from across the room. Issues of structural integrity such as sagging ceilings or obstacles are easy to identify. With all of these benefits, it makes sense to have a TIC with you at all times.
Let’s look at how you can use a TIC when entering a smoke-filled structure: Scan the room with your TIC once you enter the structure using a three-pass technique. The first pass is across the ceiling looking for heat accumulation, potential vent points, and structural integrity. The second pass is across the middle of the room looking at the physical layout and its contents as well as the location of any secondary egress points. The third pass is across the floor looking for collapsed victims and any special hazards. All three scans take less than 10 seconds but are important to maintaining proper orientation with your TIC. The actual navigation of the room should not be done with your TIC. That’s correct. I would not use the TIC for the actual act of navigation, since you can move quicker without it once you know the layout of the room.
By using your basic firefighting skills and confirming, by touch, the mental map that you developed during the second pass with the TIC, you will be able to move faster through the structure. If something were to happen to the TIC such as if you drop it or lose it, if the battery dies, or if the TIC malfunctions, you can get back because you know how you got there. You know where the secondary egresses are because you physically touched them as you navigated. As you move around the room, you should pause and rescan the room using the three-pass approach so that you can observe changing fire conditions.

The United States Navy’s Office of Naval Research (ONR) Biorobotics Program, working in cooperation with engineering students and faculty at Virginia Tech University and the University of Pennsylvania, has developed an adult-sized, humanoid robot that carries a hose to fight live fires aboard U.S. Navy ships.
SAFFiR
The Shipboard Autonomous Firefighting Robot (SAFFiR) is constructed from aluminum; stands five feet, 10 inches tall; weighs 170 pounds; and can send a one-inch blast of water at flames without stopping, faltering, or falling.
SAFFiR uses three types of sensors to navigate the spaces of a ship and locate the source of a fire, says Tom McKenna, PhD, program officer for the ONR Biorobotics Program. “SAFFiR uses a digital camera and a thermal imaging unit to see through the smoke and to detect heat and a scanning radar to allow for accurate mapping,” McKenna says. “The robot has 33-degree freedom of movement; it can walk, bend its legs, swivel its head, hold a hose, and operate a hose with its hands.”

In 2014, ONR put SAFFiR through a demonstration test aboard the USS Shadwell, a U.S. Navy experimental facility that has a fire control laboratory where suppression technologies can be demonstrated on live fires. During the demonstration, SAFFiR carried a one-inch hoseline and nozzle to suppress a fire using a concentration of water and foam. McKenna points out that SAFFiR has not been fire-hardened yet. “The robot was standing at the door of the compartment when it was suppressing the fire on the USS Shadwell,” he says. “But, all the personal protection equipment that human firefighters use to fight fires can be applied to the robot too.”
Dennis Hong, PhD, a professor at UCLA and founder of its Robotics & Mechanisms Laboratory (RoMeLa), helped develop SAFFiR when he was a professor at Virginia Tech. Hong notes that the shipboard environment is designed by humans for humans. “Hallways are very narrow, there are sharp 90-degree turns, ladders and stairways are impediments-all of which are an impossible environment for wheels or tank treads,” Hong says. “So, we designed a humanoid robot that could go everywhere on a ship that a human could.”
