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!
