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

smell the odor of the man-made chemical added to

can smell the odorant in these fuel gases.
­ •­Learn­to­recognize­the­odor­of­propane­(LP)­gas­and­

than happy to give you a scratch and sniff pamphlet.
Use it to become familiar with the fuel gas odor.
­ •­Smoking­can­decrease­your­ability­to­smell.­Being­
around an odor for a period of time can affect your
sensitivity to that particular odor. Odors present in
animal confinement buildings can mask fuel gas odor.
•­The odorant in propane (lP) gas and natural gas
is colorless and the intensity of its odor can fade
under some circumstances.
­ •­If­there­is­an­underground­leak,­the­movement­of­gas­
through the soil can filter the odorant.
­ •­Propane­(LP)­gas­odor­may­differ­in­intensity­at­different­
levels.­Since­Propane­(LP)­gas­is­heavier­than­air,­there­
may be more odor at lower levels.
• always be sensitive to the slightest gas odor. If you
continue to detect any gas odor, no matter how small,
treat it as a serious leak. Immediately go into action as
discussed previously.
