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!
• 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 propane (LP) gas tank or cylinder fuel supply valves,
or the main fuel supply valve located at the meter if you use
natural gas.
• Propane (LP) 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.
• Use your neighborÊs phone and call y our 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 any leaks, check for further leakages, and then relight
the appliance 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 (LP) or
natural gas. You must determine if you can smell the odorant
in these fuel gases.
• Learn to recognize the odor of propane (LP) gas and natural
gas. Local propane (LP) gas dealers will be more than happy
to give you a scratch and sniff pamphlet. Use it to become
familiar with the fuel gas odor.
