From 1st January 2008 customers who live in a multi-dwelling building, such as a flat, must have Flame Supervision Devices attached to all hob burners. Only gas cooking appliances fitted with flame supervision devices to the hob may be installed in these types of dwelling from 1st January 2008. If you live in a flat and buy a gas appliance without FSDs fitted to the hob burners you will find that CORGI registered engineers will not fit the appliance in your property.
The new guidelines apply to all domestic properties, but not properties which are used for commercial purposes only. Detached, semi-detached, terraced houses and houses with loft conversions are not covered by the document, although customers living in this type of property may choose to buy a gas appliance with FSDs for their additional safety.
What is a Flame Supervision Device?
Flame Supervision Devices (FSDs) shut off the fuel supply to a gas hob to prevent accumulations of gas should the flame go out for whatever reason. Preventing accumulations of gas is important for safety as there are many possible sources of ignition in any kitchen and this could lead to an explosion or a fire. FSDs therefore make gas hob burners safer as they detect there is no flame and automatically switch off the gas. Flame Supervision Devices may also be known as Flame Safety Devices or Flame Failure Devices.
