Carbon Dioxide (CO2) occurs naturally in the environment, if you use Oxygen to breath as a plant or animal then you also exhale CO2. Plants consume CO2 to grow, therefore it is an essential requirement for life.
Carbon Dioxide is also produced during:
- combustion in diesel and petrol vehicles
- natural gas used for cooking and heating,
- wood and coal burning etc.
- Increased levels of Carbon Dioxide are used in greenhouses to force plant growth.
Carbon Dioxide in Industry:
- as a shielding gas in welding
- fire extinguishant
- used as a refrigerant gas.
- CO2 is the bubbles in carbonated ‘fizzy’ drinks
- the ‘bubbles in bread and rising agents.
- in greenhouses to force plant growth
- constitutes dry ice.
In the atmosphere CO2 is present at around 400ppm. This will increase rapidly in a closed room with people breathing normally, as CO2 is exhaled. Learn more about the hazards of CO2 and how to choose the correct CO2 portable detector.
