Methane.

[johnleeknoefler]

Sewers can build up methane. Methane is actually lighter than air by about 40% but will build up if not vented properly. So the guy would of set off a methane explosion very easily by holding a match near the manhole cover where the hole for the hook is. Good thing the kids were not hurt.

It almost looks like his arm gets torn away but I'm pretty sure it's just the fabric of his jacket. Still effing awesome!

I love the way he avoids getting his head crushed by the cover.

Yup, sewers may kill, expecially if some assHOLE throws firecrackers into the sewer through a HOLE after high explosive biogas accumulated inside it ...

A man was seriously injured by sewage gas explosion on Sunday in central China's Hunan Province. But the injured man himself was the one to blame to cause the accident.

A video recorded by surveillance cameras in the residential area where Mr. Cai, the injured man lives, shows that he was setting off firecrackers in the neighborhood. The explosion took place when he threw a firecracker into the sewer through a hole on the manhole cover, with the two kids looking from nearby. In a split of a second, Mr. Cai was blown by two meters away from where he stood.

Another video from a surveillance camera shows that the manhole cover weighing some 20 kilograms was blown up to as high as the third floor of a nearby building. The victim's coat was torn into pieces by the blast.
The kids, his son and nephew, were lucky enough to escape unhurt.
Residents in the community rushed Mr. Cai to a hospital.
A doctor in the hospital said that the victim suffered from facial burns and inhalation injury. He remained in critical conditions.
The explosion was believed to be caused by high explosive biogas accumulated inside the sewer.
