The Huntsville Fire Department says it’s a decision made for safety reasons. “It’s got to do with the safety of the firefighters mostly,” says Huntsville Fire Prevention Officer Mike Vadlja. “Once we’re keeping the fire controlled and there’s no risk to life or property, we will pull the firefighters out overnight and they’ll be back in the morning to continue extinguishing the hotspots.” Hotspots are active parts of a fire that could reignite and spread. Once a fire is under control, firefighters find and extinguish remaining hotspots to prevent the fire from starting up again.
