Detecting a pipeline leak
Pipeline leaks are rare but it’s important for you to know how to recognize the signs of a leak. In most cases you may see, hear or smell the leak.
You may see:
- Water bubbling in creeks, ponds and rivers
- Amber or black coloured liquid
- A rainbow sheen on the surface of water
- Dead or dying vegetation on or near a pipeline ROW
- Stained or melted snow or ice on or near the ROW
You may hear:
- A hissing or roaring sound – oil and gas travel through the pipeline under pressure
- Flowing liquid sound as pressure is released
You may smell:
- Tar, oil, rotten egg, or skunk odour
What to do if a leak occurs
- Leave the area immediately in an upwind direction and warn others to stay away
- Do not light a match, start an engine, use a telephone or cell phone or turn on/off any electrical appliances, and avoid potential ignition sources which may cause an explosion or fire
- Do not drive into an area where you suspect a leak or vapor cloud, and do not touch or operate pipeline valves
- Avoid making contact with escaping liquids or vapors as potential hazards
- Call ‘911’ or your local emergency services number from a safe location
- Contact the regulatory agency by telephone
