Three people are recovering after a food truck exploded Friday evening at a Fresno Christian High School football game.
Investigators are now saying what may have caused the propane tank inside the truck to ignite and blow-up.
Investigators say it was caused by a propane tank in a food truck.
Instead of being outside the truck the propane was inside the small trailer.
"With that cylinder being in the confined area that seems to really be what happened the main contributing factor to the explosion," said John Creasy from the Fresno Fire Department.
The propane tank was near the cooking area when the gas was released inside the trailer, it was close to a flame that started a fire.
"That's why you're always going to want to use these containers, propane containers outside so if there is expansion of gas it can escape into the environment and not cause a fire," said Creasy.
Three people were injured, one was knocked unconscious by the blast, another suffered burns and the third was cut by debris.
Firefighters say this is a good reminder to check your propane tanks if you use one to barbeque or for camping.
"Anytime you're using it and it's been a long time since you used it last, you're always going to want to check it. Make your connections. Get a soapy solution of water spray around your connection points see if you have any bubbles. If bubbles are forming that means you have a gas leak," said Creasy.
Replace the tank and hoses if you spot a leak.
If your tank does not have an overfill or escape value to release built up pressure, exchange it for a new tank that does.
