What happens when a line is hit?

Learn to recognize signs of trouble. You may be able to detect a gas leak from a pipeline by sight, smell or sound.

• Smell: Natural Gas is odourless, therefore mercaptan, which smells like “sulphur” or “rotten egg”, is added as means to help alert of leaks.
• Sight: Natural gas is colourless, but vapour, a plume or “ground frosting” may be visible at higher pressures. A gas leak may also be indicated by bubbles in wet or flooded areas, distinct patches of dead vegetation, dust blowing from a hole in the ground or flames if the leak has ignited.
• Sound: A hissing or roaring noise (if it is a high pressure line) could also indicate a natural gas leak.

In a wide-open area, because natural gas is lighter than air, the natural gas escapes up into the atmosphere, reducing potential danger of explosion or fire. In an enclosed area, there is great concern for safety and immediate evacuation of the area may be required.

How does Rocky Gas Co-op Ltd. respond?

To repair a hit line and restore service, generally Rocky Gas Co-op will:

• Make the area safe by identifying the source of the problem and ensuring the site has been cleared of anyone whose safety may be at risk. This may include evacuation of nearby homes or buildings and, if necessary, shutting down the natural gas and/or electrical power to the area.
• Dig down to the line.
• Shut off the line upstream of the break to stop the flow of natural gas.
• Make the repair to the line.
• If required, gain access to each home or building to re-light the furnace and natural gas appliance pilot lights.
• Depending on the nature of the hit line, other organizations such as the local fire department and or appropriate government agencies may also be involved.
