Unsafe gas appliances can produce a highly poisonous gas called carbon monoxide (CO). It can cause death as well as serious long term health problems such as brain damage.
CO is produced by the incomplete burning of gas and Liquid Petroleum Gas (LPG). This happens when a gas appliance has been incorrectly fitted, badly repaired or poorly maintained. It can also occur if flues, chimneys or vents are blocked.
Oil and solid fuels such as coal, wood, petrol and oil can also produce carbon monoxide.
CO poisoning occurs when you breathe in the gas and it replaces oxygen in your bloodstream. Without oxygen, your body tissue and cells die. Even small amounts of the gas can cause CO poisoning, and long term effects can include paralysis and brain damage.
