1.General Description A colorless, odorless gas at room conditions Shipped as a liquid confined under its own vapor pressure. Noncombustible. Nontoxic 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 Bromotrifluoromethane to rupture violently and rocket.
3.Air & Water Reactions Slightly soluble in water.
4.Reactivity Profile: Bromotrifluoromethane may react with aluminum to produce substantial heat. Other halogenated hydrocarbons, such as fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane produce sufficient heat in this way to melt aluminum pieces. The vigor of the reaction appears to depend on the degree of fluorination and the vapor pressure
5..Health Hazard Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.
6.Fire Hazard Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
