Three dozen people are homeless following a massive, two-alarm fire at a south Nashville apartment complex Tuesday night.
Building 11 at the Brentwood Oaks Apartments located in the 800 block of North Oak Drive off Old Hickory Boulevard caught fire around 7:30 p.m.
A total of 18 units were destroyed or damaged.
The blaze is believed to have sparked in the building's attic.
Nashville Fire Department spokesperson Kim Lawson told Nashville's News 2 the building had sprinklers, but they were of little use because they were located below the flames in the attic.
Fire officials said the exact cause of the fire is under investigation.
Lawson said it could be several days before a cause is determined due to the building's extensive damage.
In a call to 911, the frantic caller can be heard saying, "This fire, within 15 seconds, went out of control. People are running for their lives."
All residents made it out safely thanks, in part, to David Carpenter, who helped notify residents.
"I knocked on a lady's door and she ran back inside and got her cat," he said, adding, "It spread quickly, very quickly. When I got up there maybe two or three apartments were on fire, but you could see the smoke coming from the vents and down by the other buildings. About five minutes later it all erupted."
Fire officials told Nashville's News 2 one firefighter suffered hypertension and was taken to the hospital where he remained in stable condition Wednesday.
Another fractured his foot and was treated and released.
The Brentwood Police Department assisted with the blaze.
The American Red Cross was also notified and planned to provide assistance to displaced families.
Many residents planned to stay with friends and family or at the Four Points by Sheraton Hotel two miles away.
Angela Renner's apartment wasn't damaged in the fire but she chose to stay at the hotel anyway.
"There was just so much smoke and noise, we had to go," she told Nashville's News 2 Wednesday.
"Its amazing that no one in the apartments was hurt," added her husband, Jamie.
