Fuel Gas Odor
Propane gas and natural gas both contain a
man-made odorant added specifically for detection of
fuel gas leaks. If a gas leak occurs, you should be able to
smell the fuel gas . THAT’S YOUR SIGNAL TO GO INTO
IMMEDIATE ACTION!
■ Do not take any action that could ignite the fuel gas.
Do not operate any electrical switches. Do not pull any
power supply or extension cords. Do not light matches or
any other source of flame. Do not use your telephone.
■ Get everyone out of the building and away from the area
immediately.
■ Close all fuel supply valves.
■ Propane gas is heavier than air and may settle in low
areas. When you have reason to suspect a propane
leak, keep out of all low areas.
■ Contact your fuel gas supplier and your fire
department. Do not re-enter the building or area.
■ Stay out of the building and away from the area until
declared safe by the firefighters and your fuel gas
supplier.
■ FINALLY, let the fuel gas service person and the
firefighters check for escaped gas. Have them air out
the building and area before you return. Properly trained
service people must repair the leak, check for further
leakages, and then relight the heater for you.
Odor Fading - No Odor
Detected
■ Some people cannot smell well. Some people
cannot smell the odor of the man-made
chemical added to propane or natural gas. You must
determine if you can smell the odorant in these fuel
gases.
■ Learn to recognize the odor of propane gas and natural
gas. Local propane gas dealers and your local natural
gas supplier (utility) will be more than happy to give you
a “scratch and sniff” pamphlet. Use it to become familiar
with the fuel gas odor.
■ Smoking can decrease your ability to smell. Being
around an odor for a period of time can affect your
sensitivity to that particular odor.
■ The odorant in propane gas and natural gas is
colorless and the intensity of its odor can fade under
some circumstances.
■ If there is an underground leak, the movement of gas
through the soil can filter the odorant.
■ Propane gas odor may differ in intensity at different
levels. Since propane gas is heavier than air, 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.
Attention - Critical Points to
Remember!
■ Propane gas has a distinctive odor. Learn to recognize
these odors. (Reference Fuel Gas Odor and Odor
Fading sections above).
■ If you have not been properly trained in repair and
service of propane gas and natural gas fueled heaters,
then do not attempt to light the heater, perform service
or repairs, or make and adjustments to the heater on a
propane gas or natural gas fuel system.
■ Even if you are not properly trained in the service and
repair of the heater, ALWAYS be consciously aware of
the odors of propane gas and natural gas.
■ A periodic sniff test around the heater or at the heater’s
joints; i.e. hose, connections, etc., is a good safety
practice under any conditions. If you smell even a small
amount of gas, CONTACT YOUR FUEL GAS SUPPLIER
IMMEDIATELY. DO NOT WAIT!
■ Do not attempt to install, repair, or service this heater or
the gas supply line unless you have continuing expert
training and knowledge of gas heaters.
