Almost 70% of commercial kitchen fires originate in extraction canopies and ductwork. Grease deposits are highly flammable – a small flame from chargrilling or flambéing can ignite built-up grease and track rapidly through ductwork with devastating consequences.
Extraction systems have been known to catch fire even after kitchens close, as residual heat from cooling equipment builds in grease-laden canopies. Regular deep cleaning eliminates this risk.
