In case of an emergency
Call 9-1-1 . If this service is not available in your region, call 1 800 361-8003 .
Natural gas is odourless. A very smelly substance is added so leaks can be detected. This substance, called mercaptan, gives off a strong smell of rotten eggs.
What to do?
1. Avoid flames and sparks.
- Do not smoke.
- Do not turn on any appliance near the leak, not even a cell phone or a light switch – static electricity could produce a spark.
2. Leave the building immediately or move well away from the leak if you are already outdoors.
- Without delaying your exit, on your way out, you could open doors and windows (or leave them open) to ensure maximum ventilation.
3. Call 9-1-1.
- If this service is not available in your region, call 1 800 361-8003.
If you are feeling dizzy or nauseous, or you have a headache, especially near a natural gas appliance, leave the building immediately and call medical services at 9-1-1.
An appliance that is not working properly can cause carbon monoxide poisoning. Other unusual situations, such as a flood, ice storm or abundant snow, may call for special measures being taken.
