CARBON DIOXIDE, GAS

SECTION 2: Hazards identification

This material is considered hazardous by the OSHA Hazard Communication Standard ( 29 CFR 1910. 1200 ) WARNING! EMERGENCY OVERVIEW Simple asphyxiant - this product does not contain oxygen and may cause suffocation 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 a high concentration of carbon dioxide can cause reduced hearing acuity, changes in respiration, and increased blood pressure and pulse Keep at temperatures below 52OC / 125OF Appearance Colorless Physical State Compressed gas Odor Odorless

Principle Routes of Exposure

Inhalation. Acute Toxicity Inhalation Simple asphyxiant. May cause suffocation by displacing the oxygen in the air. Exposure to an oxygen- deficient atmosphere (<19.5%) may cause dizziness, drowsiness, nausea, vomiting, excess salivation, diminished mental alertness, loss of consciousness, and death. Exposure to atmospheres containing 8-10% or less oxygen will bring about unconsciousness without warning and so quickly that the individuals cannot help or protect themselves. Lack of sufficient oxygen may cause serious injury or death. Depending on concentration and duration of exposure to carbon dioxide may cause increased respiration, headache, mild narcotic effects, increased blood pressure and pulse, and asphyxiation. Symptoms of overexposure become more apparent when atmospheric oxygen is decreased to 15-17%. Eyes None known. Contact with rapidly expanding gas near the point of release may cause severe harm. Skin None known Skin Absorption Hazard No known hazard in contact with skin Ingestion None known

Potential chronic health

Chronic harmful effects are not known from repeated inhalation of concentrations below PEL/TLV
