Sniffy Says: Smell Gas? Act Fast!

En Español

Hi, kids! I’m Sniffy. As a skunk, I’m an expert in stinky odors—like the “rotten egg” type odor that’s added to natural gas. That yucky smell lets you know if there’s a possible natural gas leak.

And you know what? If you smell that stinky rotten egg odor, you’ve got to act fast!  This means don’t delay—get away!

Remember these tips as you leave:

  • Move a safe distance away from the area of the yucky smell.
  • Don't use or touch anything electrical, like flipping off light switches or turning off the TV— things Mom and Dad would normally have you do before you leave the house.
  • Tell an adult to call Nicor Gas at 888.Nicor4U (888.642.6748) or 911 once you are out of the area where you smell the yucky odor. Stay away from the area until Nicor Gas or emergency personnel let you know it is safe to return.
