Report a Possible Natural Gas Leak

     

How to identify an outdoor or pipeline gas leak:

  • You can identify a possible gas leak by following your nose, eyes and ears.
  • Pure natural gas is colorless and odorless. Before the gas is delivered to your home, an odorant called “mercaptan” is added to give gas its distinctive odor so you can smell a leak immediately. Mercaptan makes the gas smell like sulfur or “rotten eggs.”
  • If you hit a gas line while digging, smell a strong gas odor in the air, see or hear any unusual occurrences such as: a high-pitched whistle or hissing sound, blowing dust, dead vegetation in a normally green area, continuous bubbles in an underwater area or ground fires, you may be observing signs of a leak in a natural gas line. Always use caution near an outdoor gas leak and recognize the possible hazards, such as fire, ignition or explosion!

 

 

     

What to do if you discover a gas pipeline leak:

  • Immediately abandon any equipment being used in or near the area - do not shut down a motor vehicle or electrical equipment. Your personal safety should be your first concern.
  • Avoid any ignition sources, such as using a cell phone or starting equipment. Any type of spark could cause an ignition or explosion.
  • Evacuate the area by foot and try to prevent others from entering the area.
  • Notify Ameren Illinois at 800.481.1154 or Ameren Missouri at 800.552.7583 as soon as possible.
  • If, at the moment, you are unsure who should be notified, call 911 and advise them of the location and nature of the situation.
  • Never attempt to repair or backfill any damaged or potentially damaged pipeline.

 

How to identify an indoor or appliance gas leak:

  • You can identify an appliance gas leak by a faint “rotten egg” odor.
  • Pure natural gas is colorless and odorless. Before the gas is delivered to your home, an odorant, call mercaptan is added to give gas its distinctive odor - an odor that’s recognized immediately as a “rotten egg” odor!
