Exactly! And none of that would happen with LNG because natural gas is lighter than air, it would all rapidly rise into the sky and make a very pretty, and harmless, fire.

And speaking of lumber: https://bangordailynews.com/2020/07/29/news/a-scene-from-hel... (I need a better link, but basically the cars with hazardous material did not leak, and the fire was from lumber.)

Surprise surprise, Lumber is actually more dangerous than LNG! Because none of that would have happened with LNG. With LNG it all dissipates very fast.

32 dead because of derailment of LPG transporting train. Is the hazard posed by LPG much different to LNG?

Petroleum gas is heavier than air so it stays at ground level for an extended period of time, natural gas is lighter than air so it is dispersed quickly. The gasses in petroleum gas also have significantly lower ignition temperatures.

Yes. Propane is heavier than air, so it sits on the ground and just burns and burns.

LNG rises up into the air and is gone.
