Power Lines Safety

Following an electrocution recently in Saint-Gabriel-de-Brandon, Hydro-Québec shares a safety reminder about checking for power lines before doing any outdoor work.

Hydro-Quebec says to remember the most basic safety rule: don't let anyone or anything get near power lines. Be aware of the danger when working at heights and using long or tall equipment (ladder, long-handled skimmer).

Here's what you should always do before climbing up or using long or tall equipment:
-Look for power lines nearby.
-Keep everyone and everything at least three metres away from a medium-voltage line.
-Be sure that nothing touches the low-voltage lines. Even though they're insulated, the sheathing may be cracked or damaged.

Identifying dangerous lines

Never go near medium-voltage lines. These lines are located at the top of poles and are often confused with surge arresters. They are thin metal wires without an insulated sheath. They are mounted on insulators, which look like small porcelain bowls. These unsheathed lines may look harmless, but they are extremely dangerous.

Just below the medium-voltage lines are the low-voltage lines. These are the lines that connect houses to the power system. The term "low-voltage lines" may make it sound like they aren't dangerous, but they are! They can transmit hundreds of amperes, enough to cause serious injury.
