Refueling: Liquid Petroleum Gas

Liquid petroleum gas (LPG) is a commonly used fuel for forklifts.

Forklift Fuel Filling

It is a safe fuel when handled properly. When handled improperly, it can cause serious injury or death.

  • LPG vapor is heavier than air and will seek the lowest lying area. If not adequately dissipated, it will collect in pockets and possibly ignite when exposed to a heat source.
  • LPG is extremely flammable.
  • LPG is extremely cold when exposed to the atmosphere. If your skin is exposed to LPG, you can get frostbite.

Below are the requirements and recommended best practices for refueling:
