Although carbon dioxide is a normal part of the air we breathe, it can be dangerous if you're exposed to it at high levels. You can find all the information below on carbon dioxide and how to protect yourself against leaks and remain safe.

What is carbon dioxide (CO2)?

Carbon dioxide is naturally produced when people breathe out. It is a colourless, tasteless, odourless gas. The level of CO2 in your home is related to the number of people in your home. You may have a safety risk if appliances are creating high CO2 levels.

Carbon dioxide is different to carbon monoxide, which can be dangerous even in small doses. You'll need to take different safety measures to protect against carbon monoxide safety.

Can you get a CO2 detector for your home?

Carbon dioxide detectors are not available to buy for homes. The best way to protect against high levels of carbon dioxide is to make sure you contact a Gas Safe registered engineer to perform an annual maintenance and safety check.

What if I'm exposed to high levels of CO2?

Some symptoms of high levels of carbon dioxide include:

  • Drowsiness
  • An inability to concentrate
  • Headaches
  • Increased heart rate
  • Dizziness
  • Muscle twitches
  • Rapid breathing

If you experience any of these symptoms, and believe it is because of a carbon dioxide leak, you should seek immediate medical attention.
