KITCHEN CANOPY CLEANERS

A Fire Waiting to Happen

Extraction system filters can never eliminate all vapourised grease which, together with debris, condenses onto the canopy plenum, duct and fan surfaces. This build-up now only requires heat - readily available in every kitchen - to trigger off a frightening process. A spark or flame is notnecessary, as spontaneous combustion can occur.The grease in the duct acts as a fuse, carrying fire through the duct and the building. Fire, smoke and hot gases may break out at any penetration, hole, joint or discharge point or following heat-induced collapse of ductwork.Temperatures up to 1200degC transmit heat through the metal to distort, destroy or ignite nearby material... such as duct support hangers, packing materials, electrical systems and litter.In this way fire can spread rapidly... following the duct route which may be difficult and dangerous for fire fighters to access.
