Leak Recognition and Response

Knowledge and awareness are essential for natural gas safety. A gas leak is usually recognized by smell, sight or sound:

Smell. Natural gas is colorless and odorless. Typically a distinct and recognizable odorant (known as mercaptan) is added for quick detection and recognition.

Sight.
A dust cloud, mist, fog, bubbles in standing water, or vegetation that appears to be dead or dying for no apparent reason.

Sound.
An unusual noise like roaring, hissing, or whistling.

If you suspect a leak:

  • MOVE to a safe location.
  • CALL local emergency responders at 911 and Iroquois Gas Control at 800-888-3982.
  • DO NOT strike a match, use telephones, operate engines and motors, switch lights or appliances on or off, or even turn on a flashlight in the area where you smell gas. These items can produce sparks that might ignite the gas and cause an explosion.

For Emergency Personnel:

  • SECURE the site and take steps to eliminate ignition sources.
  • EVACUATE the general public from the vicinity of the leak.
  • CONTROL secondary fires.
  • DO NOT try to extinguish a gas burning fire unless there is a threat to life.
  • CONTACT Iroquois at 800-888-3982.

For Excavators:

  • STOP work, shut down all equipment, and evacuate to a safe distance.
  • CALL 911 if there is blowing gas.
  • CALL Iroquois at 800-888-3982.
  • DO NOT strike a match, use telephones, operate engines and motors, switch lights or appliances on or off, or even turn on a flashlight in the area where you smell gas. These items can produce sparks that might ignite the gas and cause an explosion.
  • ALERT everyone on the premises.
  • KEEP the public and traffic away.
  • DO NOT try to fix the pipe or slow the rate of leaking gas.
  • NOTIFY Iroquois immediately at 800-888-3982 if you suspect or become aware of a dent, scratch, or coating damage to the pipeline.
