Carbon Dioxide

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.

The Compressed Gas Association (CGA) specification G-6.2, Grade H is considered standard for commercial carbon dioxide.
