Know the smell

Natural gas is odorless and tasteless. To make sure you know when there’s a gas leak, we add a harmless gas called mercaptan to give it a rotten-egg smell.

Know what to do

Although natural gas isn’t toxic, it is highly flammable. If you suspect a leak:

  • Evacuate your home immediately.
  • Don’t use electrical switches, phones, garage door openers, motors, matches or lighters and don’t smoke.
  • Once outside, call Union Gas at 1-877-969-0999 or 911 from a safe distance.

Know your alarms

Smoke alarms and carbon monoxide (CO) alarms won’t detect a natural gas leak. Only a natural gas alarm or combined natural gas/CO alarm will be set off if there’s a leak.
