What is carbon monoxide?
Carbon monoxide is a gas that’s poisonous to humans. It’s produced when gas or oil appliances (like cookers or boilers) are faulty or haven’t been well looked after.
Carbon monoxide is dangerous because you can’t sense it. It has no colour, taste or smell. Luckily, your home comes with a special alarm which can tell whether there’s carbon monoxide in the air.
How to stay safe from carbon monoxide
- Check your home has a carbon monoxide alarm. This works just like a smoke alarm. It will go off if CO is in the air. Make sure to regularly test the alarm by pressing the button. Replace the batteries when they run out
- Get all oil and gas appliances checked once a year by a professional
- Make sure there’s ventilation for appliances, including portable heaters. Don’t block any air vents
- If your alarm goes off or you think there’s CO in the air, turn off the appliance you’re using and call the National Gas Emergency Service on 0800 111 999 immediately.
