2.3 Other hazards

May ignite on contact with air or water. Reacts with water to form corrosive acids. Use a back flow preventative device in the piping. Do not open valve until connected to equipment prepared for use. Use only with equipment of compatible materials of construction, rated for cylinder pressure. Close valve after each use and when empty. When returning cylinder install valve outlet cap or plug leak tight. Extremely flammable. May form explosive mixtures in air. Vapors may spread long distances and ignite. Immediate fire and explosion hazard exists when mixed with air at concentrations exceeding the lower flammability limit (LFL). May react violently with water. Do not breathe gas. Poisonous, corrosive liquid and gas under pressure. Corrosive to eyes, respiratory system and skin. Direct contact with liquid can cause frostbite. Wear self-contained breathing apparatus and protective suit.
