SECTION 2: Hazards identification
EMERGENCY OVERVIEW: Colorless, volatile liquid with ethereal and faint sweetish odor. Non- flammable material. Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac arrhythmia may result from exposure. Vapors displace air and can cause asphyxiation in confined spaces. At higher temperatures, (> 250° C), decomposition products may include Hydrochloric Acid (HCl), Hydrofluoric Acid (HF), and carbonyl halides such as phosgene.
Health hazards
SKIN: Irritation would result from a defatting action on tissue. Liquid contact with skin could cause frostbite. EYES: Liquid contact can cause frostbite, which may be severe. Mist may irritate. INHALATION: REFRON®-12 is low in toxicity in animals even at a concentration of 5% (50,000 ppm); however, when oxygen levels are reduced to 12-14% by displacement symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur. At high levels, cardiac arrhythmia may occur. INGESTION: Ingestion is an unlikely route of exposure because of its low boiling point. Should it occur, discomfort in the gastrointestinal tract would result from the rapid evaporation of the liquid. Necrosis from freezing of tissue could occur.
