Safety is our top priority – and we want it to be yours too.
Each day, you dedicate your skills and expertise to building better communities. Being equipped with the electrical knowledge and following safety routines will ensure that you return home to what matters most – your loved ones.
Prioritizing safety and adhering to proper procedures protects workers from the serious dangers that come with working near electricity.
Together, we can protect our communities from preventable accidents.
Electrical infrastructure is dangerous. Being aware of what’s above and below will protect yourself and others.
Avoid the Arc
In the past year, contact with overhead wires has increased 3x.
Take extra caution when handling equipment and tools to ensure you’re within the safe distance limits - staying at least 3 to 6 meters away.
Know what's below
Always request a locate from Ontario One Call before starting any digging project. The service is free and it's the law - for all projects big or small.
Plan ahead to avoid power loss, damage liability and personal injury.
Following a safety routine will protect you against preventable accidents.
Assess for overhead or underground hazards
Confirm you have current locates to avoid hitting dangerous underground infrastructure.
Large equipment or tools?
Look up to ensure you have safe clearance distances when operating machines.
Designate a signaler or spotter
This important role acts as your second set of eyes and ears on the ground.
Having a partner in safety can help guide the operation of equipment safely.
Know the safe distance limits
All equipment and workers need to keep a safe distance away from power lines to prevent high voltage contact. Remember, the higher the voltage, the higher likelihood that electricity will jump or “arc” to you or your tools.
750 to 150,000V
150,001 to 250,000V

You can help keep workers safe by sharing these important safety reminders with your networks, employees and teams.
Large Vessel Moves
Hold the Pole
As part of your safety routine, when you first arrive on site perform your hazard assessment. You need to be aware of where all power lines are located and consider where your safe distance limits are.
Power lines as well as the surrounding air space, which insulates the line, can be hazardous. While it is obvious that you should not touch a power line, operating equipment too close to a power line is risky, too. Always ensure you designate a signaler or spotter who can guide you to perform your work safely.
Avoid the arc
You or your equipment can attract electricity without even touching the wire itself. Electricity can arc or “jump” through the insulating space between a wire and a conducting object like a truck or a ladder. The higher the voltage, the more likely it is for an arc to occur.
Safe Distance Limits
Depending on the voltage, you need to stay between 3 to 6 metres away (10 to 20 feet). If you aren't sure, contact us at 1-888-664-9376.
750 to 150,000 volts
150,001 to 250,000 volts
Whether excavating or digging with a shovel, contact Ontario One Call to request an underground cable locate. Plan ahead to avoid power loss, damage liability and personal injury.
As part of your safety routine, before starting your work assess for underground hazards. Confirm you have current locates and review them for the digging area.
If using an excavator, also beware of your machine's reach above and designate a signaler or spotter to help guide you away from overhead lines. If working close to overhead lines, ensure you stay in the safe distance limits of 3 to 6 metres, depending on the amount of voltage within the lines.
Visit OntarioOneCall.ca or call 1-800-400-2255 to request your free locate.
A service representative will clearly mark where the underground infrastructure runs through your dig area and will provide a locate sheet that includes a diagram of what has been located.
If markings are not required, you will still receive a response from the utility to indicate that your work area is clear. Do not dig until you have received all responses.
Follow any additional digging instructions outlined by each utility on your locate.
Follow these steps if you come into contact with a power line:
Any movement may result in a serious injury or fatality
The equipment (and you) may now be at the same electrical potential as the power line and there may be a current flowing through to the ground. Do not touch anything outside the equipment. You might create another path to the ground for the electrical current.
Stay at least 10 metres away
Call 911 or the emergency responders in your area.
Responders will be in touch with Hydro One.
