Your security, our priority
A safe energy
Natural gas is one of the safest sources of energy there is. In Quebec, more than 209,000 customers, including a high percentage of schools, hospitals, businesses and large companies, use it every day
Not toxic
Natural gas is a safe energy and it is not toxic. Medical research has shown that people can breathe air with a natural gas concentration as high as 25% without any harmful effect on their health. It is the lack of oxygen in the air and not natural gas that might cause illness.
Easy to detect
In its natural state, natural gas is odorless. Its signature smell comes from mercaptan, a substance added to natural gas in order to be able to detect it. Thanks to mercaptan, natural gas can be detected in the air at concentrations of as little as 0.2%.
Lighter than air
If natural gas escapes into the air, it simply rises and dissipates into the atmosphere. Open doors and windows to ensure maximum ventilation. It does not accumulate on the ground, unlike propane and gasoline.
Does not ignite easily
Natural gas does ignite easily. For this to happen, a leak must spring in an enclosed space and the gas must mix with oxygen in the air at a concentration of 5-15%. The temperature must also be extremely high for natural gas to ignite -- 538 °Celsius-- or there would have to be a flame or static electrical discharge caused by a socket. We tell our clients of the importance of using a competent contractor, one of Énergir's Partners , for installing natural gas appliances. The proper installation of natural gas appliances prevents leaks that could cause a natural gas explosion.
Prevention basics
How to recognize a natural gas leak? By its smell. Natural gas is odorless. A very smelly substance is added so leaks can be detected. This substance, called mercaptan, gives off a strong smell of rotten eggs.
What to do?
- Avoid flames and sparks. Do not smoke. Do not turn on any appliance near the leak, not even a cell phone or a light switch – static electricity could produce a spark.
- Leave the building immediately or move well away from the leak if you are already outdoors. Without delaying your exit, on your way out, you could open doors and windows (or leave them open) to ensure maximum ventilation.
- Call 9-1-1. If this service is not available in your region, call 1 800 361-8003.
Did you know that three-quarters of the breaks to underground pipes are caused by the clumsiness or negligence of the people digging? Around your building, there may be essential underground systems like these that you and your neighbors rely on: gas lines, power lines, television cables.
What to do before you dig?
Before starting any work that calls for digging, be it to install a pool, fence or patio, you or your contractor must contact Info-Excavation: Online Locate Request with Info-ex or 1 800 663-9228. It's free!
You have appointed a contractor to do the work? Ask him if he has made the necessary checks. Every broken pipe means that the fire department and Énergir's emergency service are called to intervene.

Carbon monoxide (CO) is an odorless and colorless gas. It is produced in small quantities by gasoline engines and other appliances that burn fuel with only partial or incomplete combustion. If CO accumulates due to appliances not being well-maintained, or if they are not working properly, it could cause serious health problems, even death. However, a natural gas appliance that is well calibrated is just as safe as a standard-compliance electrical appliance.
Symptoms of CO poisoning
The symptoms are headache, nausea, dizziness, vomiting.
What to do?
Leave the building immediately. If someone is sick or unable to move, carry her or him outside. In all cases of illness, contact emergency medical services by dialing 911. Before re-entering the home, air out all the rooms and determine the cause of the carbon monoxide presence.
How to prevent poisoning?
- Have your natural gas appliances regularly and carefully maintained. Maintenance must be performed by a qualified technician with practical knowledge of the operation, installation and disposal of combustion appliances.
- Install a carbon monoxide detector that meets CSA 6.19 or UL 2034 standards, available in large department stores. Just like a smoke detector, it will alert you if the amount of carbon monoxide exceeds a predetermined threshold. Using a carbon monoxide detector is mandatory in certain cases, such as in special-purpose buildings, business establishments of more than two stories and residential buildings of more than two stories or more than eight units. However, regardless of your building, your municipality may have stricter regulations than the Building Act or that apply to buildings not covered by the Act. In all cases, to ensure your safety, the Régie du bâtiment, the CNESST and fire services always recommend having a detector installed.
- Make sure that your exhaust vents and chimneys are working properly, and that the air intake and exhaust vents are cleared of snow in the winter.
In the event of a break in a natural gas pipeline or any other component of the natural gas distribution system:
- Stop work immediately;
- Avoid contact with any sources of flame or spark, including light switches and telephones;
- Move quickly away from the source of the leak and leave the building;
- Call 9-1-1 once you are in a safe location;
- Wait for the professionals to confirm that it is safe before re-entering the building.
The exterior natural gas installations (connection, meter, air intake and exhaust pipe) must be accessible at all times. The connection must therefore be kept clear of any snow or ice accumulation. This situation could lead to the interruption of the natural gas supply or a substandard appliance performance
As with every other energy sources, the regular maintenance of natural gas appliances by certified professionals is essential. An appliance that complies with safety standards and is well calibrated is totally safe and will allow you to obtain optimal performance.
- The natural gas flame should be blue. Avoid using an equipment with a yellow or orange flame (other than a fireplace) or that is unstable.
- For the safety of your building and its occupants, it is crucial to never store flammable or combustible materials near natural gas appliances. These materials include, but are not limited to chemicals, solvents, paints, oils, etc.
- Maintain the appliance's air intake and exhaust vents, making sure that nothing is blocking the ventilation or the exhaust of combustion gases.
- Poorly maintained appliances may give off carbon monoxide (CO) which can have harmful effects on health. Please have a CO detector that meets CSA 6.19 or UL 2034 standards and avoid serious problems.
- To ensure that your appliances are working properly, have them inspected by experts regulary. Make sure that you contract with a company that is licensed by the Régie du bâtiment du Québec (RBQ) and a member of the Corporation of Master Pipe-Mechanics of Québec (CMMTQ). Technicians and plumbers working on natural gas appliances must hold an appropriate certificate of qualification in natural gas equipment issued by Emploi-Québec. Énergir Partners offer maintenance programs adapted for you appliances.

The natural gas industry has been using trenchless technology for years to install its underground infrastructures. While this approach saves time, is cost-effective and has little impact on the environment, some natural gas lines installed using this technique may have inadvertently intersected with a sewer service line.
What to do?
Some cases therefore call for being extra vigilant. If you try to clear a blocked sewer service line using mechanical tools or a high-pressure water jet, you could inadvertently damage a natural gas line. This could cause a gas leak, creating a potentially dangerous situation.
- Call Info-Excavation at 1 800 663-9228 and select the emergency option.
- If Info-Excavation can confirm that there is no interference between the natural gas and sewer service lines, you will be given verbal authorization and a file number indicating you can proceed.
- If there are natural gas lines, a crew will be sent to the site to locate the natural gas and the sewer service lines.
- If a natural gas line does interfere with the blocked sewer service line, the situation will be corrected immediately and a document will be issued subsequently, allowing you to proceed with the work.
