GAS EMERGENCIES

Natural gas leaks are rare but can occur in a variety of places, so it is important to be aware of the signs of a leak. Further, knowing what to do when you suspect a leak is just as critical so you can protect you, your community and the system.

Because natural gas is colorless and odorless, Unitil adds a harmless, non-toxic chemical that makes it easier to detect a gas leak before it can create a hazardous situation. The chemical additive is called Mercaptan, and it gives the rotten eggs smell to natural gas. If you aren't familiar with it, we can provide a "scratch-n-sniff" card that provides you with a sample of the odor by calling our Customer Service center at 866-933-3821. Natural gas is also lighter than air, so if it escapes, it rises into the air and dissipates quickly.


A gas leak is often recognized by sight, sound or smell:

Sight:

  • Dirt being blown or appearing to be thrown in the air
  • Water bubbling or being blown into the air at a pond, creek, river or other wet area
  • Fire coming from the ground or appearing to burn above the ground
  • Dead or dying vegetation on or near a pipeline right of way in an otherwise green area
  • Dry or frozen spot on the right of way

Sound:

  • Hissing, blowing or roaring sound

Smell:

  • Rotten egg odor of Mercaptan

If you suspect a gas leak:

  • Leave immediately. Move to a safe place, at least 300 feet away.
  • Do not try to turn off your gas meter.
  • Warn others to stay away from the area.
  • Call 911 and Unitil when in a safe location far from the gas leak.

If you suspect a gas leak, do not:

  • Use a lighter, match or candle, open flames or operate anything that could cause a spark (such as cell phones, lights, appliances, flashlights, garage door opener or power tools).
  • Open exterior windows or doors in an attempt to ventilate.
  • Try to find the leak yourself or operate any pipeline valves.
