An explosion at a Phoenix welding business ignited a two-alarm fire on Thursday near downtown Phoenix, the Phoenix Fire Department said.
The explosion occurred at the Phoenix Welding Supply, which is on Seventh Street, north of Buckeye Road.
About 70 Phoenix Fire units responded to the scene. Seventh Street was closed north of Buckeye Road.
"On arrival, [crews] found every smoke, heavy fire to the back of a small warehouse," said Phoenix Fire Department Captain Jorge Enriquez. "It looked like, when they made their way back there, that they had some debris back there with some tanks to the back of the warehouse."
There was debris from the explosion on Seventh Street, including one of the tanks that exploded.
"Crews went ahead and surrounded it and cooled it off," said Enriquez.
The fire was started by at least four large acetylene welding tanks, according to Enriquez.
Firefighters were told to exit the hazardous area until it can be determined what is in the tanks.
Crews at the scene were able to keep the fire away from a warehouse that contained dozens of oxygen and other combustible tanks.
Fire officials say the blaze was contained within 30 minutes and there are no reported injuries.
It's still unclear how the fire started.
There were no injuries reported.
