Firefighters battled a blaze at a gas station that was being demolished Friday morning.
According to Fort Lauderdale Fire Rescue, a crew was in the process of tearing down the Texaco gas station at 1700 Cordova Road, just off Southeast 17th Street.
Crews were working with a welding torch in the gas station's car wash, and workers said something then sparked, Local 10's Jeff Weinsier reported.
The man who workers said was using the welding torch when the explosion happened denied having a welding torch.
Witnesses say they heard a loud explosion, followed by smoke and fire.
When fire crews arrived, the structure was "fully involved" and there was a partial roof collapse, said spokesman Matt Little.
Firefighters got to the fire before it spread to a nearby shopping center. The cause is still under investigation.
No injuries were reported.
Sky 10 was above the scene at the 2-alarm fire.
