Technical Characteristics of Carbon Dioxide (CO2) |
|
| Description: | Carbon Dioxide is a natural component of air at approximately 0.03% Increased concentrations of carbon dioxide replace the oxygen content of the air producing an Oxygen Deficient, toxic atmosphere. |
| Properties: | ColourlessOdourlessHeavier than air – Relative density 1.52Acidic taste at high concentrations |
| Risks: | Depletion of the oxygen in the air, causing asphyxiationHeadache, nausea, unconsciousness and death |
| 300 – 400 PPM | Typical atmosphere |
| 600 – 800 PPM | Acceptable indoor air quality |
| 1,000 PPM | Tolerable indoor air quality |
| 5,000 PPM | Average exposure limits over 8 hours |
| 6,000 – 30,000 PPM | Concern, short exposure only |
| 3 – 8% | Increased respiration and heart rate |
| 10% + | Nausea, vomiting and unconsciousness |
| 20% + | Fast unconsciousness, death |
