Five firefighters were fired and one volunteer was suspended after a Snapchat video surfaced showing a fellow member of the Houston fire department being hazed.

The video revealed a firefighter at the Westfield Fire Department in Texas was doused with water and covered with mustard, flour, and yogurt while he was strapped down to a backboard.

Fire Chief Stephen Whitehead called the hazing 'unacceptable' and 'dangerous' before launching an internal investigation, KPRC reported.

The video showed a firefighter restrained and tied to a backboard at the main station on Lauder Road, about 12 miles north of downtown Houston.

He was soaked with water from a tanker truck, and covered in mustard, flour, popcorn butter, chocolate, yogurt and ice, KPRC reported.

One firefighter can be heard telling the victim, 'Dude, you're crying. You want to quit? Just say it.'

Another man could be heard warning the others not to put the video on social media, although it emerged on Snapchat. A five-minute clip was sent to KPRC.

Whitehead, who called the hazing 'unacceptable', said the victim was a firefighter who had just graduated from rookie status.

The fire chief also said the victim could have been injured by the restraints.

He told the local news station: 'We're here to protect lives and property, not - especially your own, you know - not cause harm.'

Whitehead launched an internal investigation, and later said five part-time firefighters were terminated. One volunteer was 'suspended indefinitely'.
