Heavier than air. Easily liquefied. Contact with the unconfined liquid may cause frost bite by evaporative cooling. May asphyxiate by displacing air. A flame may flash back from a point of ignition to source of a leak. Under prolonged exposure to fire or heat containers may rupture violently and rocket."}]
