What do you do if you smell natural gas in your home or a building? Alternatively, what if you smell it outside?
Of course, this is a trick question since natural gas is odorless, and technically you are smelling the odorant in the gas stream. In any case, if you are sensing that rotten egg, sulfur-like odor, then you know that there is a good chance that natural gas is present, and you need to take action.
The most common indicator that there is a natural gas leak is the mercaptan rotten egg smell. Additionally, you may hear hissing or a blowing sound, perhaps from a gas appliance or the source itself. It may be very soft or loud, depending on the line pressure. Outside the building, you may see dead or wilting plants or trees. Drooping leaves and flowers or discolored fruit and vegetables can alert you that there may be a natural gas leak in the area. It is also possible to see spiraling or swirling dirt. Lastly, if you see bubbles in standing water, it may indicate that natural gas is present.
What not to do if you smell gas?
If you suspect that natural gas (or any combustible gas) is present, do not do anything that’ll cause a spark. Natural gas is ignitable, and the tiniest spark can trigger an explosion. In this case,
- Please do not touch any electrical switches (do not turn them on or off).
- Do not use any electrical appliances or devices, including doorbells, garage door openers, telephones, elevators; do not even use your cell phone near a suspected leak).
- Do not light a match. Please stay away from any ignition sources or open flames (do not attempt to blow it out).
- Do not start any motor vehicle engines or electrical equipment.
- Do not attempt to repair a gas leak.
What to do if you smell natural gas in your home?
It would be best if you used some discernment. Is the odor very slight, or is it strong?
- If it is strong, leave the building immediately. If it is very slight, open the windows, then leave.
- Go to a safe place, outside the smell of gas (certainly not downwind of it), and call 911 to report a gas leak.
- Of course, follow any directions from the emergency responders.
