SECTION 2: Hazards identification

EMERGENCY OVERVIEW CAUTION! High-pressure gas. Can cause rapid suffocation. Can increase respiration and heart rate. May cause nervous system damage. May cause dizziness and drowsiness. Self-contained breathing apparatus may be required by rescue workers. Odor: None THRESHOLD LIMIT VALUE: TLV-TWA, carbon dioxide, 5,000 ppm; 15 min STEL, 30,000 ppm (ACGIH, 2004). TLV-TWAs should be used as a guide in the control of health hazards and not as fine lines between safe and dangerous concentrations. Copyright © 2000, 2004, Praxair Technology, Inc. Page 1 of 8 All rights reserved. Revised WARNING: Concentrations above 10% carbon dioxide may cause nervous system damage. The following Extendapak nonoxidizer mixtures contain 10% or more carbon dioxide: EX 10, 12-16, 23-29, 41,42, 46-51, 55-58, 61-63, 66, & 67. EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE: INHALATION–Most of these mixtures are asphyxiants. Effects are due to lack of oxygen. Mixtures containing carbon dioxide are also physiologically active, affecting circulation and breathing. Moderate concentrations may cause headache, drowsiness, dizziness, stinging of the nose and throat, excitation, rapid breathing, excess salivation, vomiting, and unconsciousness. Lack of oxygen can kill. SKIN CONTACT–No harm expected SWALLOWING–This product is a gas at normal temperature and pressure. EYE CONTACT–May cause a stinging sensation EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: No harm expected. OTHER EFFECTS OF OVEREXPOSURE: Damage to retinal or ganglion cells and central nervous system may occur.

Medical Conditions Generally Aggravated by Exposure

OVEREXPOSURE The toxicology and the physical and chemical properties of the mixture components suggest that overexposure is unlikely to aggravate existing medical conditions. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: 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 humans. CARCINOGENICITY None of the components of this mixture is listed by NTP
