According to Government statistics, in 2012/13 there were over 2,300 fires in Restaurants, Cafe's, Public houses. London Fire Brigade sources, report that there is a kitchen extract duct work fire, on average, every 9 days in the Greater London alone.


Fires are rarely started within a kitchen ventilation system. Most fires start from faulty overheating appliances, thermostat failure on deep fat fryers is a common cause along with flames from uncleaned Salamander grills or flares from Charcoal grilles.



Flash over fires can typically generate temperatures between 700º C - 1000º C but if they continue, can rise to above 1200 ºC.  The FPA RC44 (Fire Risk Assessment) advises that grease within a ventilation system will spontaneously ignite between 310ºC and 360ºC, and the older the grease deposits, the lower the ignition point.  Regardless of where the grease deposits are within the system, they will ignite when the temperature in the system rises above 310ºC - 360ºC.  It is temperature, not direct exposure to flame that will cause spontaneous ignition.



Once a fire take hold within the ductwork system, it is capable of spreading the fire to other parts of the building. Hot gases escaping from poorly fitted ducting joints or access panels can ignite rubbish or other detritus close to the duct; in addition, metal is a good conductor of heat and can transfer the heat to wooden or other combustible structures of the building or material close to, or touching the ductwork, ie toilet rolls, paper boxes etc.



For restaurants, catering businesses, hotels and takeaways, keeping your extraction and ducts in perfect working order is vital to ensuring your kitchen is efficient, safe and compliant.It is now becoming more and more a requirement of your insurance to have the work carried out at least every 12 months but many of our clients are requesting it to be done twice a year.
