In an Emergency
Pipeline leaks are extremely rare. However, accidents do occur. Pipeline leaks can be very dangerous, so protect yourself by being able to identify the signs of a leak.
If you notice any of the following signs, there may be a leak.
- An unusual whistling, hissing or roaring sound can be heard nearby to a pipeline right of way or warning signs
- A smell of petroleum or mercaptan, which smells like rotten eggs. Mercaptan is added to natural gas, which is otherwise odourless, to give it a sulphur-like odor to warn of a leak
- Vegetation can appear discoloured or damaged
- A build up of frost on the ground or pools of liquid along a right-of-way
- Bubbles rising in free-standing water
- Isolated vapour or mist clouds
What to do in the case of a leak
If you notice any of the signs there may be a pipeline leak, take immediate action!
- Leave the area immediately — if possible, walk into the wind for at least 750 metres
- Warn any others nearby to evacuate, particularly if there are children or others requiring assistance
- Extinguish any fires, smoking materials and potential ignition or spark sources – including any unnecessary electronic equipment
- Call 911!
- Call the pipeline company — look for pipeline right of way and warning signs for emergency call numbers
Leaks are very rare but can be dangerous. If you think there may be a leak, take appropriate action! Better to contact the pipeline company and emergency responders than to leave things to chance.
