Carbon Dioxide/Ethylene Mixture,

SECTION 2: Hazards identification

Emergency Overview CAUTION! High-pressure gas. 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: 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: No evidence of adverse effects from available information. SKIN ABSORPTION: No evidence of adverse effects from available information SWALLOWING: This product is a gas at normal temperature and pressure EYE CONTACT: Vapour may cause a stinging sensation. EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: No evidence of adverse effects from available information. 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: One published study has reported an increased incidence of cardiac malformations in offspring of female rats exposed for a single 24 hour interval to 6% Carbon Dioxide. Although the study suffers from design and reporting flaws, the results must still be considered significant. There is no information available to confirm or refute the effects reported. The relevance of this information to humans in unknown. CARCINOGENICITY: Classified A4 (Not classifiable for human or animal.) by ACGIH, 3 (Not classifiable for human.) by IARC [Ethylene].
