Why do I need a carbon monoxide detector?

Carbon monoxide is colourless and odourless, so you need specialist equipment to tell if it has reached dangerous levels. CO can build up around faulty ventilation and heating equipment, so it's important to monitor these areas so you can respond quickly to potential emergencies.

Gas Detection: Carbon Monoxide Detection

Carbon Monoxide is a deadly toxic gas that has no smell and cannot be seen or tasted. Its presence is lethal causing death and injury, it can be caused by poorly installed or maintained heating appliances, chimneys, flues and gas fired cooking appliances. Even low levels of CO can impair judgement and greatly increase risk of accidents and injury in motorists and machine operators.
