About Carbon Dioxide (CO₂)
Carbon dioxide (CO2) is a colorless, odorless gas that occurs naturally in Earth's atmosphere. It's composed of one carbon atom bonded to two oxygen atoms. While CO2 makes up only about 0.04% of the atmosphere, it plays a crucial role in both natural processes and commercial applications.
What is CO₂?

Key Facts
Safety Considerations
Important Safety Information
CO2 is heavier than air and can displace oxygen in enclosed spaces. High concentrations can cause asphyxiation. Always ensure proper ventilation in areas where CO2 is stored or used.
CO2 cylinders contain gas under high pressure. Never tamper with cylinder valves, regulators, or fittings. Use only approved equipment and follow proper handling procedures.
Liquid CO2 and dry ice are extremely cold and can cause cold burns (frostbite) on contact with skin. Always use proper protective equipment when handling.
CO2 storage areas should be well-ventilated. Consider CO2 monitors in enclosed spaces where significant amounts of CO2 are stored or used.
Store cylinders in well-ventilated areas, keep cylinders upright and secured, protect from extreme temperatures, and separate full and empty cylinders.
