Surveillance video captured a horrifying scene when gasoline ignited at a Phoenix gas station, lighting a man on fire.

The manager of the gas station said the victim's friend said they had been joking around, and then moments later, there was an explosion.

"He said his friend was just messing around, and evidently struck a match, and that's when everything blew up," said Phillip Butler, general manager at the Chevron gas station.

Cashier Benjamin Gonzalez told that as soon as he saw the fire, he ran outside, pulled the nozzle out of the pump and doused the whole thing with water.

"By the time I got there, the guy was on fire, running around all crazy," said Gonzales.

It was Gonzalez' first week on the job. He admitted he was a little scared.

"I didn't want the whole thing going on fire, don't want an explosion in here, you know," said Gonzalez.

The driver who had been pumping gas ran from the pump as soon as the SUV caught fire. Moments later, the driver ran back to the car to rescue a baby from the back seat.

A woman also jumped out the back window to escape the flames.

"Thank God they pulled the kid out in time," said Vanessa Nuno, a gas station employee who witnessed the incident.

The mother of the victim said Monday night her son, who was on leave from Iraq, suffered burns to 20 percent of his body. She said he was in critical but stable condition.

No one else was seriously hurt.
