Four children in Ste. Adele risked their lives this week when they climbed a Hydro tower.

The children, all students at Augustin Norbert Morin high school, were filmed climbing the tower while their fearful fellow students looked on.

Tommy Pasieka, the 12-year-old who filmed the event, showed it to his mother when he got home, and she notified school officials and Hydro Quebec.

"I was there like, oh my gosh, they're gonna die. They're gonna be electrocuted, they're gonna die for sure," said Pasieka. "I was really scared."

The school's principal declined to comment but the school board did issue a letter to parents urging them to talk to their kids about high-risk stunts and promising to punish the four climbers. The four teens in the video have been identified and may face fines.

Climbing a high tension tower can be deadly. The power running through the 120 kV transmission lines can easily arc to an individual and electrocute them.

Serge Abergel of Hydro Quebec said there are other dangers in climbing the tower.

"First of all the height of the towers, they're very high and if you fall off you risk severe injury. Second of all, which is much more serious, you're also very close to high power transmission lines and they're exposing themselves to the risk of being electrocuted by an electric arc, which is the whole power from the line going through their bodies and down to the ground," said Abergel.

Hydro Quebec sent a crew to the area on Wednesday, about 1 km from the school, but a teenager still managed to climb up the tower afterward.

The utility, and the Sureté du Quebec, are now conducting regular patrols in the area.

Hydro Quebec says there are no plans to put up fences around the pylons because it would be unfeasible. There are 30,000 km of electical power lines in Quebec, and putting up fences around each would be expensive.
