| Hazard Information | Back Directory | 【General Description】
1.1.1-Trifluoroethane is a colorless, highly flammable gas. 1,1,1-TRIFLUOROETHANE(420-46-2) 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. | 【Reactivity Profile】
Halogenated aliphatic compounds, such as 1,1,1-TRIFLUOROETHANE, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. | 【Air & Water Reactions】
Highly flammable. | 【Health Hazard】
Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases. | 【Fire Hazard】
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. CAUTION: Hydrogen (UN1049), Deuterium (UN1957), Hydrogen, refrigerated liquid (UN1966) and Methane (UN1971) are lighter than air and will rise. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. |
