Jobsite safety

Whether you're working for a company or on your own property, if you are working near overhead or underground power lines, it is your responsibility to ensure the safety of the people on the jobsite.

Your responsibilities

The following points must be taken into account when working near electrical installations.

Comply with safety regulations

Keep yourself and everything else (tools, work instruments, etc.) at least 3 metre away from the power lines. Avoid touching the power lines or any related equipment. Avoid digging within 1 metre of underground electrical structures. Avoid touching the grounding system.

Planning and coordinating work

Gather relevant information such as the schedule, work plans and photos. Ensure coordination between Hydro‑Québec and the various stakeholders. Ensure that you are onsite when the safety measures are being put in place.

Contact Info-Excavation

Before starting any excavation work, you must submit a locate request to Info-Excavation. It's simple and free of charge.

Only authorized specialists may carry out vegetation control work

If you notice that a tree located too close to the power system needs to be pruned or cut down, don't do it yourself. Instead, contact an arborist who is a member of the Québec chapter of the International Society of Arboriculture. They will submit a jobsite safety request if necessary.

Read and apply the agreement

The form titled Convention - Intervention à proximité de lignes électriques (agreement for conducting work near power lines) is a mandatory agreement under which Hydro‑Québec can authorize and oversee the work by ensuring the safety of the jobsite, employees and the public. The form is provided following a jobsite safety request assessed by Hydro‑Québec and is not accessible online.

How Hydro‑Québec can help you

Hydro‑Québec can help you when your work is carried out near electrical installations. Please note that there may be fees attached to certain measures.

Free assessment of hazards

Hydro‑Québec can inspect the site and identify the hazards related to working near power lines and underground infrastructure. If necessary, we can propose safety measures (costs may apply).

Implementation of safety measures

If safety measures are necessary, Hydro‑Québec implements applicable protective elements, explains what needs to be verified each day and coordinates the signature of the agreement. Once the work is completed, Hydro‑Québec removes the protective elements upon your request.

Examples of safety measures

Illustration of a scaffolding installed near a power line with orange insulating devices covering the conductors. This temporarily allows workers to get closer to the line, i.e. to within 1.2 metres.

Installation of conductor covers

With conductor covers installed, you can get as close as 1.2 m to a line. This temporary measure can only be used for a maximum of seven days.

Moving medium-voltage lines

Hydro‑Québec moves lines using temporary H-frames. Visual markers indicate that the lines are energized (live) to remind you to keep at least 3 metres away.

Illustration of a power line identified as being de-energized and a visual marker indicating that the power has been cut and that it is safe to approach the line.

De-energizing lines

De-energizing a line means cutting power to it, so you can approach it safely. There are visual markers indicating that the line is de-energized (dead).
