Natural gas in its natural form has no odor. The ‘smell’ that you recognize is actually the smell of chemical added by the gas company to help us detect gas leaking into the air. This harmless odor, which smells like rotten egg, is known as mercaptan.
So, what to do if you smell gas inside the house?
If you suddenly smell a faint odor of gas in the air, straight away open all the windows.
Did You Know? A person who is having a blocked nose or may have lost his/her sense of smell could still be able to tell if there’s a gas leak in his/her home. Physical symptoms can include: dizziness, fatigue, nausea, headaches and irregular breathing. So, if you find this happening to you when you’re inside but not out, you could have a gas leak.
Do not switch any appliances, lights and even your computer, on or off. Don’t even try to turn off the mains.
Do not use the telephone. Electrical currents in switches and telephones, even the smallest spark could set off an explosion.
Simply said, don’t do anything that could create a spark, especially lighting a cigarette indoors!
Let your neighbors know if you think they may be affected by the leak – it’s better to be safe than sorry.
Once you and your family members are safely outside, call your natural gas provider to report a gas leak. If you don’t know the number, simply dial emergency services 9-1-1.

Stay away from the building until an official familiar with the situation tells you it is safe to return.
Once your gas has been shut off, do not try to turn it back on. Only a qualified person may perform this task.
Once the natural gas leak is fixed, the odor will remain, but the danger has passed once the area has been ventilated. You should have no worry at all if personnel from the fire department have inspected the house. The fire department has sensors to detect what type of leak and the concentration in the air. If they said it was OK, then you should have no worries.
