Carbon monoxide alarms are now fitted as standard to most new vans, as manufacturers become increasingly aware of the hazards this poisonous gas can cause.
It is produced from fuel-powered equipment such as barbecues, but has no colour, taste or smell, making it very difficult to detect.
The alarm has a seven year life, without any need to replace the batteries. It is also compact so ideal for fitting in the van.
