Potential health effects

1,1,1,2-Tetrafluoroethane Inhalation: Misuse or intentional inhalation abuse may cause death without warning symptoms, due to cardiac effects. Other symptoms may include anesthetic effects, light-headedness, dizziness, confusion, incoordination, drowsiness, or unconsciousness, irregular heartbeat with a strange sensation in the chest, heart thumping, apprehension, feeling of fainting, dizziness or weakness. Vapors are heavier than air and can cause suffocation by reducing oxygen available for breathing. Skin: Contact with liquid or refrigerated gas can cause cold burns and frostbite. May cause skin irritation, discomfort, itching, redness or swelling. Eye: “Frostbite-like” effects may occur if liquid or escaping vapor contacts the eyes. May cause irritation, tearing, redness and discomfort. Additional Health Effects: Increased susceptibility to the effects of this material may be observed in persons with pre-existing disease of the: Central Nervous System, Cardiovascular System. 1,1,1,2,2,3,4,5,5,5-Decafluoropentane (HFC-43-10mee) INHALATION: Vapors are heavier than air and can cause suffocation by reducing oxygen available for breathing. Effects of breathing high concentrations of vapor may include: Tiredness or drowsiness. Convulsions. SKIN: Repeated and/or prolonged exposure may cause defatting of the skin with itching, redness or rash. Isopropyl Alcohol EYE: May cause pain disproportionate to the level of irritation to eye tissues. May cause moderate eye irritation. May cause moderate corneal injury. Vapor may cause eye irritation experienced as mild discomfort and redness. Vapor may cause lacrimation (tears). SKIN: Prolonged exposure not likely to cause significant skin irritation. May cause drying and flaking of the skin. SKIN ABSORPTION: Prolonged skin contact is unlikely to result in absorption of harmful amounts. INHALATION: With good ventilation, single exposure is not likely to be hazardous. In poorly ventilated areas, vapors or mists may accumulate and cause respiratory irritation. Prolonged excessive exposure may cause adverse effects. Excessive exposure (400 ppm) to isopropanol may cause eye, nose and throat irritation. Incoordination, confusion, hypotension, hypothermia, circulatory collapse, respiratory arrest and death may follow a longer duration or higher levels. Observations in animals include middle ear lining damage upon exposure to vapors of isopropanol. However, the relevance of this to humans is unknown INGESTION: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury. May cause central nervous system depression. May cause nausea and vomiting. Signs and symptoms of excessive exposure may include: Facial flushing. Low blood pressure. Irregular heartbeats.

Aspiration hazard

Aspiration into the lungs may occur during ingestion or vomiting, causing lung damage or even death due to chemical pneumonia. EFFECTS OF REPEATED EXPOSURE In animals, effects have been reported on the following organs Liver. Kidney. Kidney effects have been observed in male rats. These effects are believed to be species specific and unlikely to occur in humans. Observations in animals include: Lethargy. BIRTH DEFECTS/DEVELOPMENTAL EFFECTS: Isopropanol has been toxic to the fetus in laboratory animals at doses toxic to the mother. Poly-Tetrafluoroethylene Inhalation of PTFE dust may cause generalized irritation of the nose, throat, and lungs with cough, difficulty in breathing or shortness of breath. Inhalation of fluorine compounds released as decomposition products above 290°C (554°F) may cause polymer fume fever with flu-like symptoms in humans, especially when smoking contaminated tobacco. Repeated episodes of polymer fume fever may result in persistent lung effects. 3.
