Chattanooga firefighters responded to a trailer fire at 2619 Boyce Street shortly after 1 p.m. on Tuesday.
Some Chattanooga police officers were the first on the scene and they were told by neighbors that someone might still be inside the burning structure.
They attempted to conduct their own search, but were forced out by the heat and smoke.
Captain David Brooks and his firefighters with Engine 4 arrived a short time later. Upon hearing that someone might still be inside, Captain Brooks said his firefighters took a hand-held hoseline and made entry through the front door. Captain Brooks said the firefighters worked quickly to get the blaze under control in roughly five minutes. No one was found inside the structure.
The fire caused substantial damage to the trailer. The loss was estimated at $30,000.
The fire displaced two adults and three children. Volunteers with the American Red Cross were called in to provide assistance to the family.
The cause of the fire remains undetermined and is under investigation.
