One of the biggest challenges in keeping a commercial kitchen spotlessly clean is the regular cleaning of the canopy, fan and extract ductwork. This must be tackled, not only for the sake of hygiene, but also for fire prevention and compliance.
Airborne fat, oil and grease is a natural by-product of even the healthiest diet. Carried in the steam that rises from cooking, grease and oil particles are drawn into the kitchen extract system to be vented away to the outside. As the exhaust stream cools, grease is deposited on the metal surfaces of the hood, canopy, filters, canopy plenum, fan and ductwork.
Should a kitchen fire reach the extract ductwork, or a flash fire occur in the extract system, then the accumulated grease deposits can act as fuel, helping to spread the fire. The ductwork itself can also help to spread the fire, acting as a chimney through which smoke and flames can travel, spreading the danger to the other parts of the building.
To counter this potential fire risk, operators of commercial kitchens are required to comply with a new standard for the fire safety management of grease accumulation in kitchen extract systems, TR19® Grease.
Compliance is also essential to ensure that you don’t compromise your buildings insurance. If a fire should break out and the ductwork can be shown not to have been cleaned in accordance with TR19® Grease, many insurers will now refuse to pay out on a claim.
Ensuring legal compliance, a reduced risk of fire and greater hygiene in your kitchen are items which should always be on every maintenance menu.
