Dangerous activities near power lines
LOOK UP FROM THE GROUND. STAY AWAY FROM THE WIRES AND DON’T LET ANYBODY OR ANYTHING (TOOL, LADDER, TAPE MEASURE OR ANYTHING ELSE) GET WITHIN 3 M OF THEM.

Low-voltage lines (120–600 V) are a serious shock hazard, even though they have an insulating sheath, because they can carry thousands of amps. As a precaution, never touch them directly or indirectly, because the sheathing may be damaged, even if it doesn’t look like it.
If the three stacked wires are bare, or if the insulating sheath is obviously damaged, stay away from the wires and don’t let anybody or anything (tool, ladder, tape measure or anything else) get within 3 m of them.
For safety reasons, the law requires trees in such situations to be pruned or felled by arborists authorized by Hydro-Québec.
If the branch or tree that concerns you is also close to wires at the top of the pole, don’t climb the tree to prune it: it’s the same as going near the wires yourself. Those are medium-voltage wires. They are NOT covered by insulating sheaths and their voltage may be as high as 25,000 V.
Low-voltage lines are usually insulated and have a voltage of 120 to 240 V (sometimes up to 600 V). As a precaution, stay away from them, because if the sheathing is damaged or cracked, you could receive a very serious shock.
If you want to prune or cut down a tree near this type of wire, we recommend you call an arborist who is a member of SIAQ (Société internationale d’arboriculture Québec, the Québec chapter of the International Society of Arboriculture).
Display the list of arborists who are SIAQ members in this region (in French).
Telecommunications wires are not an electrical hazard, because they are sheathed and have a voltage of approximately 12 V.
The situation that concerns you does not require Hydro-Québec to take any action.
If a tree looks like it may damage the wires, notify the telecommunications company.
Don’t touch the plant and never try to get it off the wire. This situation is extremely dangerous.
Please provide some contact information so that we can follow up with you or obtain additional information.
Hydro-Québec will assess the situation based on the information you have provided and will contact you if necessary. Of course, we will take action in cases of immediate risk. However, if the risk is not imminent, we remind you that only the owner of the tree may request a trimming service and will have to cover the cost. If the tree is not pruned following your request, the medium-voltage lines will be cleared during preventive work carried out periodically by Hydro-Québec.
