A fire broke out at a commercial building near Phoenix Sky Harbor and dozens of firefighters worked to contain the flames on Wednesday night.

Crews were called out to the building at 40th Street and Winslow Avenue, which is just south of University Drive, just after dark when a passer-by noticed the flames, firefighters said.

The fire department says the fire caused a gas tank to explode which caused a gas line to break and send gas into the building. The gas line had a pipe about 2" in diameter.

Firefighters said the flames were so big, they had to go defensive instead of a more aggressive and offensive attack. They couldn't save the building so they mostly made sure that flames didn't spread to nearby businesses.

Multiple fire engines and ladder trucks were seen help crews battle the blaze.

Southwest Gas is working to turn off the gas.

The building is a total loss. It was used to fix semi-trucks.

There was a lot of smoke in the area which caused low visibility.

It's unclear what sparked the flames.
