Answer Wiki. It turns out that sulfur hexafluoride, SF6, is the most potent greenhouse gas ever measured. Greenhouse gas potency is measured with an unit called the GWP or global warming potential, and it takes in account the molecule's ability to absorb infrared radiation and survival in the atmosphere. SF6 is an octahedral molecule, with six S-F bonds, each capable of absorbing infrared radiation very well.
On a boat, LPG is also, by far, the most dangerous cooking fuel. Propane and butane are heavier than air, so they spill like water. Leaking propane in a house falls to the floor, usually dispersing harmlessly on air currents, but a boat is like a bowl, and leaking gas accumulates in the bottom of it.
