Bromotrifluoromethane is a colorless, odorless gas at room temperature. It is a noncombustible, nontoxic gas but can asphyxiate by the displacement of air. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket. It is also known as Halon 1301, R13B1, Halon 13B1, or BTM.
