Smell Gas? Act Fast!

Because natural gas is colorless and odorless, we've added a chemical odorant called mercaptan that makes natural gas smell like rotten eggs. This distinctive scent allows you to smell potential leaks quickly and take steps to stay safe. If you smell that stench in the air, make sure you do the following:

Natural Gas Detectors

Natural gas detectors may be installed by homeowners for an additional safeguard to detect leaks.

Here is What to Know

  • The natural gas detector measures the concentration of methane in the air and sounds an alarm to alert you before dangerous levels are reached.
  • The methane detector works by pulling in air from the surroundings and, if it detects a dangerous level of natural gas in your home its light will flash and/or it will emit a loud noise.
  • Refer to your user’s manual for the detector for specific natural gas alarm characteristics.
  • Test the device regularly. Please refer to your user’s manual for testing intervals and the procedures that explain the light and sound patterns to ensure the detector and alarm functions are working properly.
  • If the natural gas detector alarm sounds, respond immediately!
  • Assume there’s a natural gas leak. Leave the area quickly, taking everyone with you.
  • Follow the guidelines for when you smell gas - DO NOT use the telephone or any electrical appliances including light switches, garage door openers, doorbells, radios, TVs or cell phones. A spark from any of these sources could ignite the gas, causing a fire or explosion.
  • DO NOT disconnect the gas detector battery to silence the alarm. A spark could cause an explosion.
  • DO NOT assume someone else will report the leak.
  • DO NOT go back inside your home or building until company or emergency personnel say it is safe to return.
