Propane facts

  • Propane is a colorless, odorless hydrocarbon gas with three carbon atoms, and it turns into a liquid under modest pressure.
  • It is the main ingredient in liquefied petroleum gas, or LPG, which fuels grills, home furnaces, and forklifts.
  • Propane is heavier than air, so leaks collect in low spots, and suppliers add a strong-smelling odorant so that leaks can be detected.
