I agree that the correct method of filling removable lpg cylinders is when they are off of the forklift. This reduces possible damage to the forklift should a fire occur during refueling. I also think that most bulk filling stations in use are designed for only filling cylinders off of the forklift and are not equipped with the safety devices required of filling stations intended for fixed forklift lpg tanks designed to be filled on the forklift.

I am going to try to sneak into ANSI/NFPA 58 this weekend through the Canadian Standards Association (CSA) site.
