ANTIOCH, Tenn. (WKRN) — A fully-involved two-alarm fire at an Antioch apartment complex displaced 15 people and caused two firefighters to be transported to an area hospital.

Firefighters arrived to Stone Ridge Apartments on the 500 block of Piccadilly Row off Una Antioch Pike around 6:15 p.m. on reports of a structure fire. When they arrived, they found heavy smoke and flames coming from the front area of Building 4. The building has four units in total and housed 15 people.

Fire investigators say all of the residents were accounted for, and no residents were injured as a result of the fire. Two firefighters were transported to an area hospital, one as a precaution for having debris fall on them and the other for heat-related exertion. Their injuries are said to be non-life threatening.

The building was not considered a complete loss, as one unit is considered fairly unaffected. Three other units in the building were considered heavily affected. The full extent of the damage and the cause is still under investigation.

“Crews made an excellent stop, because there is a firewall in between two of the units,” said Kendra Loney, Public Information Officer with the Nashville Fire Department, “What essentially looks like happened is that the fire started on the front floor level on the right side, went out the window, vented up the side of the building, and then went into the ceiling and the roof area and then carried across the building to get into the roof on the left side. Actually, the unit on the bottom left was unaffected by smoke or fire, because they were able to stop the fire in its tracks.”

NES has been able to shut off power to the affected building, and natural gas lines to the building have also been shut off. The American Red Cross has been called out to assist the displaced residents.
