Natural gas is a safe choice!

While natural gas is one of the safest and cleanest energy sources, it is nevertheless important to follow the basic rules of prevention, maintenance and installation for natural gas equipment.

It's 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.

It's easy to detect

In its natural state, natural gas is odourless. 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%.

It's 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.

It 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

Natural gas

In Québec, more than 205,000 customers, including a high percentage of schools, hospitals, businesses and large companies, use it every day.

Prevention basics

Safety first: prevention is as easy as following your appliances' installation, usage and maintenance guidelines.

Digging without inquiring can be expensive

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 neighbours rely on: gas lines, power lines, television cables.

    Equipment maintenance

    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.

      Watch out for carbon monoxyde

      Carbon monoxide (CO) is an odourless and colourless gas. It is produced in small quantities by gasoline engines and other appliances that burn fuel with only partial or incomplete combustion. However, a natural gas appliance that is well calibrated is just as safe as a standard-compliance electrical appliance.

          Énergir and prevention

          Énergir's distribution network is one of the most modern networks in North America.Our network surveillance operates 24/7, 365 days a year. Our control centre monitors the pressure at more than 126 reading points to ensure stability and to guarantee that the natural gas network is in good working order at all times.

          The reliability of the distribution network

          Did you know that Énergir:

          • Patrols its entire 10,000 km network every two years?
          • Checks its 153,000 building connections every six years?
          • Inspects the connections to 2,600 priority buildings every year?
          • Takes 400 selective readings of mercaptan every month?
          • Responds to 90,000 requests for localization of natural gas pipes every year?

          The design and construction of Énergir’s distribution network meets the most exacting standards of the Canadian gas industry.
