I did something similiar one time putting away a coleman camping stove. I was heating it up (during the blue roaring flame stage) and it started to rain and I was going to turn everything off and the tank (with the "generator") dropped off the front of the grill. I caught the generator tube with my hand and immediately dropped it. I had HUGE blisters for a couple of months form that.
