Do You Smell Gas?

Do You Smell Gas?

What should I do if I smell gas?

Natural gas and propane gas in raw form are odorless and colorless.  A harmless chemical called mercaptan is added to give natural and propane gas a “rotten egg” smell.  If you smell natural or propane gas, leave the premise immediately.

  • Avoid any and all ignition sources.
  • Do not make calls or turn anything off or on.
  • Do not try and locate the leak.
  • Do not use anything that could cause a spark.
  • Do not use anything with an open flame.

Once you are safely away from the area, call JCCUD at 423-623-3069 or 865-475-7911 and/or 911.  Do not return to the area until safety personnel have arrived and let you know it is safe to return.

Physical Properties of Natural and Propane Gas
  • Natural gas (methane), is lighter than air and will normally rise. In a confined space, this can build up to explosive levels.
  • Propane vapor is heavier than air and will normally sink. In a confined space, this can build up to explosive levels.
