mixed with ethane, propane, butane and
pentane
The “rotten egg” smell of Methane gas is an
odorant called “Mercaptan” added to aid in leak
detection
Natural Gas and Methane are lighter than air
and may accumulate high in a room or building
Sources of Methane gas include Landfills; from the decomposition of
