There was originally a riser pipe sticking out of the top of the tank. You can't see it in those pics because it was already cut off and the hole patched before those photos were taken. Pic related shows a smaller tank before any work was done to it.

I unscrewed the valve from the top of the tank, then I filled the tank completely with water and allowed it to drain out. Filling the tank with water makes 100% sure that any vapors were removed from the tank before cutting.

Once you do cut into the tank there can be some sticky residue on the inside. That comes not from the gas itself, but from the chemicals added to the gas so you can smell it if there is a leak. It's pretty nasty. But it's easily removed by building a fire in there and burning it out.
