Canopy kitchen extracts, present in most commercial kitchens, are used to dissipate heat, grease and vapour emissions. Fat, oil and grease deposits accumulate within the system, over time, posing a serious risk of fire as flame and high temperatures ignite the deposits, causing rapid spread throughout ducts. Deposit build-up also causes blockage of air flow and wont filtrate toxin carbon monoxide as efficiently. Extracts must be cleaned regularly, in accordance with legislative guidelines, to reduce fire risk and bacterial build-up. Whilst surface cleaning of canopy and vent can be performed by kitchen staff, it is recommended that a specialist be retained for ductwork and discharge unit.
Responsibility for risk assessment lies with the building owner and managers, who are expected to identify and assess risks in the kitchen environment and implement remedial control measures. All components, canopies, extract plenum, ductwork and fan must also be inspected as recommended by Health & Safety Executive. Compromising fire safety of staff and non-staff by not ‘’removing greasy deposits through regular cleaning, based on kitchen needs’’ can cause legal action to be taken under Regulatory Reform (Fire Safety) Order, and can be also be considered negligence, which is prosecutable under Health and Safety at Work Order NI 1978. Failure to complete regular cleaning of extracts in accordance with Fire Safety and Workplace Regulations will invalidate building insurance policies and open responsible parties to corporate liability.

Coral Environmental Ltd carry out thorough cleaning of kitchen canopy extracts in accordance with TR/19 guidance notes. Cleaning is recommended on an annual basis, however individual site requirements are determined by’’ usage of equipment, types and quantity of cooking, ignition vulnerability and building occupant/users to system fire, hygiene, vermin and mechanical hazards’’ (HVCA TR/19. Internal Cleanliness of Ventilation Systems Section 7). When cooking, fumes, airborne grease, combustion products and smoke rise from the air via evacuation and filtration, and discharged outside of the site. Some of the material is retained within the ducts and vents, causing build-up and blockages over time. This retained material is highly flammable and poses a risk to staff and non-staff users. Coral Environmental ensure this material is removed, leaving an efficient, hygienic system that complies with all legislative requirements.
During the cleaning process, each extract component is cleaned and disinfected using COSHH approved chemicals and equipment. The different components of a kitchen extract system can be seen above.
