Frequently Asked Questions

In its pure form, natural gas is odorless. We add a harmless odorizing agent that produces a distinctive, strong smell that reminds some of sulfur or rotten eggs. This makes it possible for you to detect even a small leak.

Use caution! A natural gas leak can cause an explosion if ignited by a spark. If you smell gas in your home, leave your house immediately and call our emergency service number (615-388-0997, City of Portland Natural Gas On-Call Phone Number), or 615-451-3838 or 911 from another location such as a neighbor's house.

For your own safety, remember these rules in the event you smell gas:

• Do not use your electric garage door opener to leave your house. Any motorized appliance could spark, igniting the natural gas
• Do not use your phone to call us unless you are outside and away from your house. Using any type of telephone could ignite the leaking gas
• Do not turn any light switches or other electrical devices on or off. Anything electrical, even something as small as a thermostat, may cause a spark and ignite leaking gas
• Do not try to re-light the pilot light. Leave gas furnaces, water heaters and other gas appliances alone until you are certain that it is safe
• Do not smoke cigarettes or light candles. Using a lighter or a match could ignite the leaking gas

Once you are safely away from the building, call the City of Portland Gas Department or emergency services immediately:

• Between the hours of 8 am to 4:30 pm, call 615-325-6776
• After 4:30 pm or on weekends please contact one of the following:
  • On-Call Gas Phone: 615-388-0997
  • Phone: 615-451-3838
  • 911

If you hit or contact a gas line in any way, inform the City of Portland immediately at 615-325-6776 or 615-388-0997 (gas on-call phone). A gouge, scrape, scratch, dent or crease to a pipe or its coating may cause a future safety problem. It is imperative that City of Portland gas crew inspects and repairs any damage to our pipeline, no matter how minor it may seem.
