FUEL GAS ODOR
LP gas and natural gas have man‑made odorants added
specifically for detection of fuel gas leaks.
If a gas leak occurs you should be able to smell the fuel
gas. Since Propane (LP) is heavier than air you should
smell for the gas odor low to the floor. ANY GAS ODOR
IS YOUR SIGNAL TO GO INTO IMMEDIATE ACTION!

The odorant in propane (LP) gas and natural gas is
colorless and the intensity of its odor can fade under
some circumstances.
•­ If­there­is­an­underground­leak,­the­movement­of­gas­
through­the­soil­can­filter­the­odorant.

• Always be sensitive to the slightest gas odor. If­you­
continue­to­detect­any­gas­odor,­no­matter­how­small,­treat­
it­as­a­serious­leak.­Immediately­go­into­action­as­discussed­
previously.
ATTENTION ‑ CRITICAL POINTS TO
REMEMBER!
•­
Propane (LP) gas has a distinctive odor. Learn to
recognize these odors. (Reference Fuel Gas Odor and
Odor Fading sections above.
