Carbon Dioxide (liquefied Carbon Dioxide)

SECTION 2: Hazards identification

OSHA EMERGENCY OVERVIEW CAUTION! High-pressure gas. Can cause rapid suffocation. Can increase respiration and heart rate. May cause nervous system damage. May cause frostbite. May cause dizziness and drowsiness. Self-contained breathing apparatus may be required by rescue workers. Odor: None Threshold Limit Value : TLV-TWA, 5,000 ppm (ACGIH, 1998). TLV-TWA, 15 min STEL, 30,000 ppm. Effects of a Single (acute) : Inhalation - Carbon Dioxide gas is an asphyxiant with effects due to Overexposure lack of oxygen. It is also physiologically active, affecting circulation and breathing. Moderate concentrations may cause headache, drowsiness, dizziness, stinging of the nose and throat, excitation, rapid breathing and heart rate, excess salivation, vomiting, and unconsciousness. Lack of oxygen can kill. Skin Contact - No harm expected from vapor. Cold gas, or liquid or solid Carbon Dioxide may cause severe frostbite. Swallowing - An unlikely route of exposure. This product is a gas at normal temperature and pressure. Eye Contact - No harm expected from vapor. Cold gas, or liquid or solid Carbon Dioxide may cause severe frostbite. Effects of Repeated : No harm expected. (chronic) Overexposure Other Effects of : Damage to retinal or ganglion cells and central nervous system may Overexposure occur.

Medical Conditions Generally Aggravated by Exposure

The toxicology and the physical and chemical properties of Carbon Dioxide suggest that overexposure is unlikely to aggravate existing Overexposure medical conditions. Significant Laboratory Data with Possible Relevance to : A single study has shown an increase in heart defects in rats exposed to 6% Carbon Dioxide in air for 24 hours at different times during

gestation. There is no evidence that Carbon Dioxide is teratogenic in Evaluation humans. Carcinogenicity Carbon Dioxide is not listed by NTP
