SECTION 2: Hazards identification

Emergency Overview DANGER! Flammable, high-pressure gas. May form explosive mixture with air. Can cause rapid suffocation. Can increase heart rate. Can increase respiration. May cause dizziness and drowsiness. Self-contained breathing apparatus may be required by rescue workers.

Principle Routes of Exposure

Inhalation. EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE: INHALATION: May be mildly irritating to mucous membranes. At high concentrations, may cause drowsiness. At very high concentration, may act as an asphyxiant and cause headache, drowsiness, dizziness, excitation, excess salivation, vomiting, and unconsciousness. Lack of oxygen can cause death. SKIN CONTACT: This product is a gas. SKIN ABSORPTION: No evidence of adverse effects from available information. SWALLOWING: A highly unlikely route of exposure. This product is a gas at normal temperature and pressure. EYE CONTACT: Relatively non-irritating. EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: None. OTHER EFFECTS OF OVEREXPOSURE: Damage to retinal ganglion cells and central nervous system may occur.

Medical Conditions Generally Aggravated by Exposure

OVEREXPOSURE Repeated or prolonged exposure is not known to aggravate medical condition. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: A single study has shown an increased heart rate in rats exposed to 6% CO2 in air for 24 hours, at different times during gestation. There is no evidence that CO2 is tetratogenic in humans. CARCINOGENICITY: Classified A4 (Not classifiable for human or animal.) by ACGIH, 3 (Not classifiable for human.) by IARC [Ethylene]. Classified A4 (Not classifiable for human or animal.) by ACGIH, 3 (Not classifiable for human.) by IARC [Propylene].
