What to do if you suspect a gas leak

Natural gas is colorless and odorless. A chemical that smells like rotten eggs is added to make it easier to detect a gas leak before it creates a hazardous situation.

If you suspect a gas leak in your area, please follow these safety guidelines.

  • Leave the area immediately.
  • Do not turn any electrical switches on or off.
  • Do not use your cell phone or a landline. Wait until you have left the area to call for help.
  • If you are currently on a landline, set the receiver down but do not hang up.
  • Do not start your car engine.
  • When you are a safe distance from the gas smell, call 911 to report the smell of gas. Then report the leak to South Dakota 811 and the gas company.
  • Remain a safe distance from the suspected leak until someone from the gas company or an emergency responder says it is safe to return.

South Dakota 811 notifies operators of facilities whose buried lines are within the area you intend to dig. The facility operators will mark the location of their buried lines using paint or flags. South Dakota 811 is not responsible for marking buried lines.

If a facility operator marks a location with “clear” or “NO” it means that they do not have an underground service within the area you intend to dig.

Paint on the ground or colored flags indicate the location of underground utilities. Each utility uses a different color of paint to flags so the lines can be identified. Click HERE to see what each color represents.
