Carbon monoxide. Carbon monoxide is difficult to detect because it has no smell, taste or colour. This means you can inhale it without realising.

When a fire burns in an enclosed space, such as a room, the oxygen is gradually used up and replaced with carbon dioxide. The fuel is unable to burn fully and releases carbon monoxide.
