Properties of Natural Gas
Natural gas is a fossil fuel that forms naturally from hydrocarbons produced millions of years ago when plant and animal remains were buried beneath layers of soil and rock. Over time, heat and pressure combined to transform this mass into fossil fuels such as oil and natural gas.

Natural gas is more than 90% pure methane, the lightest hydrocarbon.

Signs of a Leak
Unlike the natural gas that heats your home, natural gas in many transmission pipelines is not odorized. If there is a leak, you will not smell rotten eggs. Leaks rarely occur on our system but there are signs you can watch out for that may indicate a possible leak:

• Discoloured plants in an area (dead vegetation);
• Frost on the ground when the ambient temperature is above zero; or
• Bubbles in freestanding water such as sloughs.

What to Do
If you come across a damaged pipeline, or damage one accidentally, you should:

• Shut off power equipment and motors and evacuate the area;
• Extinguish all lanterns, flares, smoking materials, etc. in the area;
• Stay clear of the area; and
• Immediately contact our 24-hour emergency number. 1-306-777-9800 collect
