Dover firefighters are using technology to change the way they attack fires.On Monday, firefighters responded to a garage fire at a home in the city, and they knew before arriving how they would fight the flames.>> Download the FREE WMUR app"At a fire scene, the first minute really sets the stage for the next hour," said Deputy Fire Chief Paul Haas.Firefighters use iPads the moment they leave their fire station. Through the application, "Public Eye," they instantly access information on where they're going, such as the distance to the closest hydrant.Showing how the program works, Haas said the home they responded to Monday is "in red, which means that we can't lay a supply line from this hydrant all the way because it's too far away."Through the tax assessor, crews can get a visual of the home or building where they're going."We never would have this view in our minds ahead of time," Haas said.Having all that information before firefighters arrive at a scene helps them to do their jobs better."It just lets you pre-plan. It lets you develop that pre-incident plan of, 'What am I going to do when I get there, where am I going to position my apparatus, am I going to lay a supply line from the end of the driveway or go right to the house?'" Haas explained.Dover fire has almost 20 iPads as each fire truck and ambulance is equipped with them. They've been using the technology for two years, but recently have been using the tablets more often as details get added to the app.Haas says the technology doesn't get them to a scene faster, but it does give them an edge."You can literally envision what you're gonna be pulling up to before you even get there," Haas said.
