Copy: Smell a stinky gas leak? Leave and call 911.

You might think I make a bad smell, but it's nothing compared to the rotten-egg smell of a gas leak - because that's downright dangerous! There could be other signs such as a hissing sound or dirt blowing.

If you smell, hear or see signs of a leak, don't do anything that might cause a spark. Leave immediately! From a safe distance, call 911 and Atmos Energy. When dealing with gas leaks, it's black and white!
