Recently was at a customers site and on the way around to back side of facillity, I noticed a forklift driver filling LP tank that was sill latched and hose still coupled to valve----while running--I asked him if this was normal and he said he was giving it a quick shot of gas and did it occaisionally to finish his shift. I asked him if he was aware that LP gas was heavier than air and collected on the ground and also the forklift was like a vacuum cleaner pulling air from the bottom around the engine and blew through the radiator, if a spark was to occur what would happen? --he thanked me and stopped filling in this manner. DO any of the Forum folks see this in your world?--- Care to share your story.....
