2.3 Other hazards
Burns with an invisible flame. Can ignite on contact with air. Extremely cold liquid and gas under pressure. Extremely flammable liquefied gas. Vapors may spread long distances and ignite. Direct contact with liquid can cause frostbite. Avoid breathing gas. Can cause rapid suffocation. Self contained breathing apparatus (SCBA) may be required. High concentrations that can cause rapid suffocation are within the flammable range and should not be entered. Immediate fire and explosion hazard exists when mixed with air at concentrations exceeding the lower flammability limit (LFL).
