PHILADELPHIA — A Philadelphia firefighter was injured Thursday afternoon in a three-alarm blaze that engulfed three residential buildings. 

More than 150 firefighters worked to prevent the flames from spreading to more neighboring residences amid hot and windy conditions, fire officials told CBS Philly. 

Philadelphia Fire Commissioner Adam Thiel told CBS Philly the blaze was "really a four-alarm equivalent fire because of the heat." 

The temperature in the city at the time of the fire was about 90 degrees, according to the Philadelphia Second Alarmers Association. 

The injured firefighter is in stable condition after being assisted by a medic at the scene and transported to the hospital, officials said. According to a fire department tweet, the firefighter suffered heat exhaustion.

Due to an interior collapse during the blaze, fire crews committed to an exterior attack. 

No other injuries were reported. Thiel estimated about 20 or more residents have been displaced.
