FORT WAYNE, Ind. (WFFT) - Fort Wayne firefighters were called to this home in the 2700 block of Chestnut Street Monday afternoon.
Multiple calls came in about a fire and an explosion.
Neighbor Jessica Crupe says it was shocking to hear the loud boom.
"We think this neighborhood's pretty safe and nothing really happens over here so it was really surprising," Crupe said.
The Fort Wayne Fire Department says the explosion was a propane tank that helped fuel the fire.
Thankfully the four people inside got out safely before firefighters even arrived.
Batallion Chief Tom Helmkamp says it took them just over thirty mintues to get the blaze out.
"We have heavy damage to the rear of the house," Helmkamp said. "The back side is completely charred up. We had fire in the attic. We had a lot of smoke when we arrived on scene, a lot of heavy fire on the back side of the house and crews did a great job."
Despite getting the fire out in a short amount of time, the fire department brought in backup.
That's because of the excessive heat.
The heat not from the fire but the outside temperatures.
Helmkamp says they train for situations like this.
He says no firefighters were hurt but some were dealing from a little heat exhaustion.
"We're rotating crews out," Helmkamp said. "Once they do, they'll use an SEBA bottle and once they empty that bottle they'll come out, dress down, cool off, drink lots of water. we're rotating crews in from other parts of the city to take over and rotate those guys back to the station to get cooled off."
Crews were out there in the elements for around two and half hours to make sure the fire was completely out.
Fort Wayne firefighters say there weren't any working smoke detectors in the home.
We're told the cause of the fire at that home is still under investigation at this time.
