flame supervision device (FSD)

The provisions of this section of Part 8 in the 2002 BSS Standards are mandatory for non-private boats where applicable.

If the burner on any of your appliances goes out and the fuel continues to flow and is ignited this could start a fire or cause an explosion. To reduce the risk of this happening appliance burners, ignition burners and pilot lights must be fitted with flame supervision devices that completely and automatically close off the LPG or fuel oil supply if the flame goes out.

Appliances in good condition and in place before 3 January 2000 are exempt from this requirement, as long as a flame supervision device is fitted to catalytic heaters, appliances with a pilot light (e.g. instantaneous water heaters) or those which normally have a continuous flame (e.g. refrigerators.)
