Carbon Dioxide is a colorless gas with a slightly pungent odor and biting taste. It will not burn, support combustion or sustain life. It is about 1.5 times heavier than air. Normally stored as a liquid, carbon dioxide exists only as a solid or gas at room conditions. The solid CO2 snow transforms (sublimes) directly to a gas without passing through the liquid phase. Carbon Dioxide is known in the food industry for carbonating drinks and preserving packaged foods. The non-flammable properties make it a popular pressurizing gas for aerosols.
Features
- A colorless and odorless gas that can cause the nose to sting in high concentrations
- Toxic in high concentrations, an asphyxiant (does not support life)
- Slightly corrosive in the presence of moisture
- Heavier than air, carbon dioxide will collect in ducts, drains and low-lying areas
- Highly soluble in water at moderate pressures
