This rarely happens but still confirms that parachutes can get stuck in electric wires. What usually causes incidents like this is the inability of the user to properly control the parachute. However, if it eventually happens that you get stuck in electric wires with your parachute, the next thing is to ensure that you don't get electrocuted.
This does not mean you cannot be electrocuted if you get stuck in electric wires, but you may have the luck to survive it. However, it is always best to weigh your options very well for deciding your next line of action when you are in a similar situation like this.
If you sense you might eventually get stuck in electric wires, you may decide to let go of the parachute and have a freefall. This actually depends on the altitude you were when you made the decision. At least, this is better than getting yourself stuck in electric wires.
