Natural gas is formed from decomposed organic plants and animal matter. In its pure state, this clean burning natural gas has no odour and is tasteless. To help make natural gas detectable, an additive called Methyl mercaptan [Mur-cap-tan] has been added. This additive smells like rotten eggs, and is used as a safety precaution to allow even the smallest leaks to be detected. We adhere to strict safety measurements making safety to our customers and community our number one priority.

While natural gas is one of the safest fuels, small gas leaks can still occur. Knowing how to detect a leak can help reduce the risks to both people and property. The following 3 ways are how to determine if you may have a natural gas leak:

  • Smell It - In its pure state, natural gas has no smell or taste. As a safety precaution, a scent called methyl mercaptan is added to natural gas before it is delivered to your home. This odour smells like rotten eggs or sulphur so that natural gas leaks can be detected.
  • See it - Natural gas has no color and is clear, but it can leave behind visible signs of a leak including patches of dead vegetation, blowing dust from holes in the ground, bubbles in wet or flooded areas or even flames. In some cases, spotting vapours or ground frosting can suggest a high-pressure leak.
  • Hear It - A hissing or roaring noise along the right-of-way of a pipeline could also indicate a natural gas leak.

If you suspect or detect a natural gas leak indoors

  • Evacuate the building immediately
  • If you can do so safely, open all doors and windows
  • Call EPCOR immediately from an outside phone
  • Don't use anything that could create static or a spark, eg. Electrical switches, lighters, matches, cigarettes

If you suspect or detect a natural gas leak outdoors

  • Call EPCOR immediately
  • Keep clear of the area
  • Don't start any motors or motor vehicles near the area of the suspected gas leak
  • Don't use lighters or matches and do not smoke
