Halocarbon 134A

SECTION 2: Hazards identification

Emergency Overview CAUTION! Liquid and gas under pressure. Harmful if inhaled. Can cause rapid suffocation. Can cause frostbite. May cause dizziness and drowsiness. Self-contained breathing apparatus may be required by rescue workers.

Principle Routes of Exposure

Inhalation. Swallowing. Skin Absorption. Skin Contact. Eye contact. EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE: INHALATION: Asphyxiant. Effects are due to lack of oxygen. Moderate concentrations may cause headaches, drowsiness, dizziness, excitation, excess salivation, vomiting, and unconciousness. Lack of oxygen can kill. SKIN CONTACT: Liquid may irritate skin. Liquid may cause frostbite. SKIN Prolonged or widespread skin contact with the liquid may result in the absorption of harmful ABSORPTION: amounts of material. SWALLOWING: An unlikely route of exposure. This product is a gas at room temperature and pressure, but frostbite of the lips and mouth may result from contact with the liquid. EYE CONTACT: Vapour may irritate the eyes. The liquid may cause severe corneal injury due to frostbite. EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: No evidence of adverse effects from available information. OTHER EFFECTS OF OVEREXPOSURE: At very high concentrations may produce cardiac arrhythmias or arrest due to sensitization of the heart to adrenalin and non-adrenalin. Exposure to fluorocarbon thermal decomposition products may produce flu-like symptoms including chills, fever, weakness, muscular aches, headache, chest discomfort, sore throat, and dry cough. Complete recovery usually occurs within 24 hours after exposure.

Medical Conditions Generally Aggravated by Exposure

OVEREXPOSURE Overexposure may aggravate preexisting disorders of the heart or central nervous system. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: None known. CARCINOGENICITY: Not listed as carcinogen by OSHA, NTP or IARC.
