Canopies, Extraction Systems & Ducting Deep Clean

Cleanliness and safety... the essential ingredients of every well-managed kitchen. At the heart of the matter is your kitchen extract system, the perfect hiding place for grease, oil and other deposits.

Keeping canopy hoods and filters regularly cleaned is the easy part. But what happens to the ductwork, the part you cannot see...

Failure to deal effectively and comprehensively with this issue is just storing up problems and a fire risk waiting to happen...

Kirklees Cleaning LTD Deep Clean clean ventilation extraction systems to your agreed specification.

We degrease and decarbonise the interior and exterior of canopies. Removing coatings of carbon and solidified cooking oils built up from cooking fumes that have spread throughout the extraction unit and trunking.

Our trained teams pay particular attention to seams, rivets and anti drip gullies, removing and cleaning grille extraction fans, cleaning fan blades, motor casing and housing.

We remove and deep clean the filters, filter housing and trunk interiors, to ensure hygiene and fire risk safety standards are continually exceeded.

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 not necessary, 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.

A Risk Too Far

The Insurance Industry is hardening its attitude on the issue. This is hardly surprising since The Association of British Insurers has recorded losses associated with dirty kitchen extract fires rising from £25 million in 1997 to £65 million in 1998. (N.B. This only takes account of direct losses in excess of £50,000).

The Insurers' Loss prevention Council recommend that at least annual cleaning of entire systems by specialists is carried out, the exact frequency to be determined by a reasoned risk assessment.

Failure to comply with the terms of a policy could mean invalidation of the entire contract, leaving the insured to carry a total loss. ... "The overwhelming important factor is inadequate cleaning of ductwork..." Mark Newton, Royal and Sun Alliance.

Kitchen extraction systems cleaned and ventilation ductwork degreased as required to comply with environmental health regulations and fire insurance specifications.

Hazards of Dirty Kitchen Ventilation Systems

Even the most efficient extraction filters cannot remove all traces of grease and dirt from the air. Over time, a layer of grease and dirt is deposited on the surfaces of ventilation ducts, canopies and extractor fans. Not only does this cause an environmental health hazard by providing a breeding ground for bacteria and foul odours, it also reduces the efficiency of your extraction system and is a major fire risk.

It is therefore essential to carry out regular cleaning of your kitchen extraction and ventilation systems as determined by an appropriate risk assessment. Failure to do so could lead to a breach of the Environmental Health Regulations and could invalidate your fire insurance policy.
