Jobsite safety

Electrical hazard awareness and safety tips.

If you’re working on a project that involves cranes, dump trucks, boom trucks, ladder trucks, bucket trucks, scaffolds, ladders or antennas, you'll likely be working close to overhead powerlines. Contact with a live powerline can cause severe injuries, and in some cases, death.

Whether you’re the property owner or a contractor, it’s your responsibility to ensure everyone on the jobsite is aware of electrical hazards and knows how to stay safe around them.

Before starting a project, you must do the following:

De-energize powerlines
Contact us at 416-542-8000 (press 4) to request your powerlines be de-energized, relocated or removed.
Have a signal person
A signal person must be on hand to assist the operator whenever power equipment (cranes, hoisting devices, backhoes, power shovels) is working near overhead powerlines.
Post warning signs
Warning signs must be posted and fully visible to all equipment operators. They should be located close to the hazard, as well as at the operator’s station. Contractors/property owners also need to provide the contractors with written notices of all hazards present on the jobsite.
Keep transformers unobstructed
Don't build or plant anything within three metres (10 feet) of transformers. In case of an emergency, crews should be able to access transformers quickly and safely.

Call before you dig

Before you start any work, make sure you obtain a locate of underground equipment — it's the law.
