What is carbon monoxide?
Carbon monoxide is a dangerous gas. Breathing it in can make you sick or even kill you.
It's hard to know if carbon monoxide is there - you can't see, smell or hear it.
Where is carbon monoxide found?
Carbon monoxide is made by burning fuels like natural gas, petrol, wood, charcoal and coal.
Many household items burn these fuels and make carbon monoxide.
Carbon monoxide can get trapped inside your home, particularly when the doors and windows are closed. This can make carbon monoxide build up to dangerous levels.
