SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an ac-
cident. Read them carefully now, then review them point by
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
Some people cannot smell well. Some people cannot smell
the odor of the chemical put into the gas. You must find out if
you can smell the odorant in propane. Smoking can decrease
your ability to smell. Being around an odor for a time can affect
your sensitivity or ability to detect that odor. Sometimes other
odors in the area mask the gas odor. People may not smell the
gas odor or their minds are on something else. Thinking about
smelling a gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under
some circumstances. For example, if there is an underground
leak, the movement of the gas through soil can filter the odorant.
Odorants in LP-gas also are subject to oxidation. This fading can
occur if there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
find out what the propane odor smells like. If you suspect that
your LP-gas has a weak or abnormal odor, call your LP-gas
dealer.
• If you are not qualified, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-gas system. If
you are qualified, consciously think about the odor of LP-gas
prior to and while lighting pilot lights or performing service or
making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
reinstalled old tanks, if they are filled and allowed to set too
long before refilling. Cylinders and tanks which have been
out of service for a time may develop internal rust which will

LP-GAS WARNING ODOR
That's your signal to go into immediate action!
NO ODOR DETECTED - ODOR FADE
SOME POINTS TO REMEMBER
point with the members of your household. Someday, when
there may not be a minute to lose, everyone's safety will de-
pend on knowing exactly what to do. If, after reading the fol-
lowing information, you feel you still need more information,
please contact your gas supplier.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immedi-
ately go into action as instructed earlier.
cause odor fade. If such conditions are suspected to exist,
a periodic sniff test of the gas is advisable. If you have any
question about the gas odor, call your LP-gas dealer. A
periodic sniff test of the LP-gas is a good safety measure
under any condition.
• If, at any time, you do not smell the LP-gas odorant and you
think you should, assume you have a leak. Then take the
same immediate action recommended above for the occasion
when you do detect the odorized LP-gas.
• If you experience a complete "gas out," (the container is un-
der no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air though openings such as pilot light orifices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having it
refilled before it is completely empty.
