物理形态与操作说明

  • 1.1.1-Trifluoroethane is a colorless, highly flammable gas. It is heavier than air and vapors may travel from a leaking container to a source of ignition causing a flame to flashback to the container. Contact with the unconfined liquid can cause frostbite. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.
