CARBON DIOXIDE GAS

SECTION 2: Hazards identification

EMERGENCY OVERVIEW Odorless, colorless, nonflammable gas. Simple Asphyxiant – This product does not contain oxygen and may cause asphyxia if released in a confined area. Maintain oxygen levels above 19.5%. Carbon dioxide acts as a weak narcotic at high concentrations (30,000 ppm). Inhalation of high concentrations of carbon dioxide can cause reduced hearing acuity, changes in respiration and increased blood pressure and pulse. Contents under pressure. Use and store below 125 °F.

Potential health effects

Exposure Limits Irritant Sensitization Yes No Teratogen Reproductive Hazard Mutagen No Synergistic Effects None reported Carcinogenicity -- NTP No IARC No OSHA No EYE EFFECTS: Liquid and cold vapor may cause tissue freezing. SKIN EFFECTS: May cause frostbite. INGESTION EFFECTS: No adverse effects anticipated. INHALATION EFFECTS: Depending on concentration and duration of exposure carbon dioxide may cause increased respiration, headache, mild narcotic effects, increased blood pressure and pulse, and asphyxiation. Symptoms of overexposure to carbon dioxide become more apparent when atmospheric oxygen is decreased to 15-17%. Chronic harmful effects are not known from repeated inhalation of concentrations below the PEL/TLV.
