Carbon Monoxide

Carbon monoxide (CO) is widely known as the silent killer. It is highly poisonous and cannot be detected by the senses. You can't see, smell or taste its presence. Exposure to even low levels of CO can cause brain damage and death.

• CO is produced by the incomplete combustion of gas, solid or liquid fuels. It arises from badly installed or poorly maintained gas appliances. Insufficient ventilation to the appliance or away from the appliance (flues and chimneys blocked) will also cause CO build up.
• Signs of CO are: yellow or brown stains around the appliance, pilot lights which blow out frequently and increased condensation inside windows. You should be aware to check for these during inspections.
• Symptoms: Fatigue, headaches, flu like symptoms such as nausea, chest pains, sudden giddiness when standing up, sickness, diarrhoea and stomach pains, erratic behaviour.
• If you suspect CO: switch off appliance, open doors and windows, visit your GP and call a Registered installer.

CO alarms are a useful precaution to give tenants advance warning of CO and investing in an alarm also protects your property. CO alarms cost between £10-£30 and can be purchased in most hardware shops. Before purchasing a CO alarm, always ensure it complies with British Standard EN 50291 and carries a British or European approval mark, such as a Kitemark. CO alarms should be installed and maintained in line with the manufacturer’s instructions.
