Great point, thanks! However, there is a tiny difference here- Natural gas is less dense than air, so it floats up and dissipates. On the other hand, propane and butane are denser than air, so they tend to settle in low areas and concentrate. Realistically that probably wouldn’t be much of a factor here, but I figured I’d mention it anyways.
