Toxicology

In moderate to high concentration carbon dioxide acts as an asphyxiant. It is a respiratorystimulant. In the so
• Appearance:colourless odourless gas
• Hazard Symbols:Solid damaging to skin and tissue; keep away from mouth and eyes. TLV: 5000 ppm (gas).
• MSDS:View
• Safety:An asphyxiant. See discussion of simple asphyxiants under ARGON. Experimental teratogenic and reproductive effects. Contact of solid carbon dioxide snow with the skin can cause burns. Dusts of magnesium, zirconium, titanium, and some magnesium-aluminum alloys ignite and then explode in CO₂ atmospheres. Dusts of aluminum, chromium, and manganese ignite and then explode when heated in CO₂. Several bulk metals will burn in CO₂. Reacts vigorously with (Al + Na₂O₂), Cs₂O, Mg(C₂H₅)₂, Li, (Mg + Na₂O₂), K, KHC, Na, Na₂C₂, NaK, Ti. CO₂ fire extinguishers can produce highly incendiary sparks of 5–15 mJ at 10–20 kV by electrostatic discharge. Incompatible with acrylaldehyde, aziridine, metal acetylides, sodium peroxide.
