If you smell
rotten eggs
it could be a
natural gas leak

You can't see or taste natural gas, which is why we make sure you can smell it. We add a harmless gas called mercaptan to make it smell like rotten eggs.

If you smell rotten eggs and suspect a leak follow these steps:

  • icon 1

    Leave your home immediately.

  • icon 2

    From a safe distance, call Union Gas at 1-877-969-0999 or call 911.

  • icon 3

    Don’t use electrical switches, appliances, phones, garage door openers, vehicles or lighters and don’t smoke.

  • icon 4

    Don’t open windows.

Install the right alarms

Smoke and carbon monoxide alarms won’t detect a natural gas leak. Use a natural gas alarm or combined natural gas/CO alarm to detect a leak.
