Power Line Safety

If you are planning to do a household project that required digging – such as planting a tree or building a deck – you should call to locate electrical or other underground utilities before you begin.

Underground Utility lines can be found throughout the city. Before you place a shovel in the ground, you should call before you dig. IT IS THE LAW.

Ontario One Call provides a free service to locate underground utilities at www.on1call.com or by phoning 1-800-400-2255.

Learn more at the Call Before You Dig page.


If you were in an accident and a power line came into contact with your vehicle, would you stay in your vehicle or get out quickly?

You should stay in your vehicle until emergency workers are able to tell you that the power is disconnected. Learn by watching the video below:

Trees interfering with power lines can create hazards

Always plant the right tree in the right place to avoid this problem.  Report overgrown trees to Thunder Bay Hydro.

How far should you stay away from a downed power line that is quietly lying on the ground?

Storms and high winds can often result in downed power lines.  Sometimes a motor vehicle accident can down a power line.

Unlike in Hollywood movies, live power lines do not always snake and spark.  They may be lying quietly on the ground.

If you see a downed power line, maintain a distance of at least 10 meters (33 feet) or about the length of a school bus.

  • Report the downed line to 911 immediately and warn others not to approach.
  • Call Thunder Bay Hydro once you are safely away from the line and after you have called emergency personnel.

Some electrical equipment is located in locked steel cabinets called transformers. 

It is very dangerous to try to open or touch the equipment inside.

If the cover is disturbed or the lock on the door is broken, please contact Thunder Bay Hydro.

Our crews need to access the transformer for maintenance and repairs.  Do not plant shrubs or erect fences around these transformers.Transformer (12).JPG

 


How do I ensure that I'm safe when maintaining my power lines?

If you wish to trim trees under your customer-owned lines, we can disconnect the power for free to ensure safe working conditions for your contractor.
