Carbon dioxide : Description and use

Description

Carbon dioxide is a component that is naturally present in air. Nevertheless, in high concentrations, it can cause asphyxiation by displacing the oxygen in the air required for breathing. When the concentration of carbon dioxide reaches 7.2% (72,000 ppm), the rate of oxygen in the air decreases to 19.5%. This concentration corresponds to the value defined in article 40 of the Registre Santé et Sécurité au Travail (French occupational health and safety records) regarding the minimum percentage of oxygen in terms of volume in the air at all work stations within a company.
Under normal temperature and pressure conditions it is a colourless, odourless gas with a pungent taste. It comes in the form of a liquefied-compressed, colourless and odourless gas.

Flammability: This product is not flammable.
