Gas flames

For Immediate Release: October 26, 2018

Tucson, Ariz. – As temperatures fall and Arizona residents use more natural gas to heat their homes and businesses, UniSource Energy Services is reminding customers how to detect and respond to a natural gas leak.

This month, UniSource is mailing an insert to customers and sponsoring a print and broadcast advertising campaign with safety tips. Here are signs of a natural gas leak:

  • A sulfur-like odor similar to rotten eggs.
  • A hissing or roaring sound.
  • Dirt blowing from the ground, unusual bubbling from a water source like a puddle, pond, creek or river, and dead or dying vegetation.

Even those whose homes lack natural gas service should be aware of these signs at all times because a gas line could be buried under a nearby street or alleyway. Customers who suspect a leak should follow these safety tips:

  • Do not use the phone, smoke, flip electrical switches or strike a match.
  • If you smell gas indoors, quickly check to see if a pilot light has gone out or if a burner valve is partially turned on. If you cannot quickly find the source of gas, leave the house immediately. Then, from a safe location, call 911 and UniSource, day or night, at 1-877-837-4968.
  • If you smell gas outdoors, do not smoke or start your vehicle. Move away from the area and call 911 and UniSource from a safe place.

UniSource also reminds customers to call 811 at least two business days before beginning any project that requires digging or other activity that could damage a gas line. To request this free service, call 811 or visit
