CARBONDIOXIDE 79
INHALATION: remove victim to fresh air, keep quiet and warm. If breathing stops, start artificial
respiration. INGESTION: do NOT induce vomiting. Give milk, egg whites, or large amounts of water.
Get medical assistance. No known antidote. EYES and SKIN: remove contaminated clothing. Flush
eyes with water for 15 min. or until physician arrives. Wash skin with soap and water; Toxicity by In-
halation (Threshold Limit Value): 5 ppm; Short-Tenn Exposure Limits: Data not available; Toxicity by
Ingestion: Grade 2; LD,, 0.5 to 5 g/kg (rat); Lute Toxicity: Causes cancer in experimental animals;
Vqor (Gas) Irritant Characteristics: Vapors cause moderate irritation such that personnel will find
high concentration unpleasant. The effect is temporary; Liquid or Solid Irritant Characteristics: Fairly
severe skin irritant. May cause pain and second-degree burns after a few minutes’ contact; Odor
Threshold 0.05 ppm.
Fire Hazards - Flash Point (deg. F): 117 CC; Flammable Limits in Air (96): No data; Fire
Extinguishing Agents: Foam, carbon dioxide, dry chemical; Fire Extinguishing Agents Not To Be Used
Not pertinent; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: The solid
often evaporates without first melting; Ignition Temperature (deg. F): 466; Electrical Hazard Not
pertinent; Burning Rate: No data.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;

Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus in excessively high CO, concentration areas. For handling liquid or solid, wear safety goggles
or face shield, insulated gloves, long-sleeved shirt, and trousers worn outside boots or over high-top
shoes to shed spilled liquid; Symptoms Following Exposure: Inhalation causes increased respiration rate,
headache, subtle physiological changes for up to 5% concentration and prolonged exposure. Higher
concentrations can cause unconsciousness and death. Solid can cause cold contact burns. Liquid or cold
gas can cause freezing injury to skin or eyes similar to a burn; General Treatment for Exposure:
INHALATION: move victim to fresh air. skin: treat burns from contact with solid in same way as
frostbite; Toxicity by Inhalation (Threshold Limit Value): 5000 ppm; Short-Term Exposure Limits:
30,000 ppm for 60 min.; Toxicity by Ingestion: Not pertinent (gas with low boiling point); Late
Toxicity: None; Vqor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor Threshold Not pertinent
