Brochure: Natural Gas Safety Guide

Natural gas usually has no smell, so you may not always be able to detect a leak that way. An odorant is added in certain built-up areas along the pipeline, but in most cases you must look out for these other signs:

  • Noise – ranging from hissing to booming
  • Dirt being blown or thrown into the air
  • Water being blown into the air at a pond or river
  • Burnt or dead vegetation
  • Fire apparently coming from the ground or burning
  • above the ground
  • A dry spot in a moist field
  • Bubbles appearing on the surface of water in the
  • vicinity of the leak

If You Suspect a Gas Leak…

  • Immediately leave the area on foot
  • Head upwind
  • Keep others 800 metres clear of the area
  • Stay upwind and out of low-lying areas
  • Do not introduce any source of ignition such as open
  • flames; striking of matches; heat; sparks; static
  • electricity and do not operate electrical switches,
  • wireless / portable radios, mobile telephones or start
  • a vehicle
