Carbon Monoxide is a gas you cannot see, smell or taste but, in sufficient quantities, it can cause permanent heart, lung or brain damage, or even kill! It is known as 'The Silent Killer'.
Carbon monoxide can be given off by any appliance, which burns a fossil fuel, such as gas, coal, oil or LPG (propane/butane). It will enter your home if your appliance is faulty, or if the room is not properly ventilated, or if the chimney or flue is blocked.
To ensure your appliances are safe, have them installed and maintained regularly by a qualified engineer. For gas appliances this means a Gas Safe registered engineer.
