A heavier-than-air gas, such as propane or gasoline fumes, would settle and accumulate near the ground. so the plumber,gas company said that it settles down though they actually donot know that the natural gas is dissipated and the propane or gasoline from natural is the one which would settle on ground<br><b>References : </b><br> your correct that natural gas is lighter than air.But when natural gas escapes into the atmosphere, it dissipates rapidly.

though they actually donot know that the natural gas is dissipated and the propane or gasoline from natural is the one which would settle on ground
