What are TR-19 regulations and how do they apply to commercial kitchens?

TR-19 is a set of guidelines published by the Building Engineering Services Association (BESA). These guidelines set out the minimum requirements for regular ductwork inspections, testing and cleaning of air conditioning, ventilation and kitchen extract systems.

It also defines the criteria for assessing the risk of fire, fire spread and potential contaminants in the ductwork system.

Kitchen Extract, Canopy & Ductwork Cleaning

How do you clean kitchen extraction systems?

This process consists of a thorough inspection of the entire kitchen duct system, including the fan, fire barrier, outlet, ductwork, and impellers. Additionally, all associated parts, such as grease filters, cowling, and access panels are removed and cleaned with care.

Recommended replacement of any defective or worn-out parts is also included in the procedure to optimise the system’s performance and ensure the safety of your chefs, waiters and kitchen porters.

Commercial Kitchen Extract, Canopy & Ductwork FAQs

Our experts have put together a list of frequently asked questions that are intended to help anyone who manages or has control over a commercial kitchen and to understand the guidelines surrounding TR-19.

What are the benefits of having kitchen extraction systems cleaned?

TR-19 duct cleaning can offer several important advantages for commercial and industrial establishments. Firstly, by clearing away dust, dirt, mould, and other pollutants from the ducts, indoor air quality is enhanced, thereby decreasing the possibility of respiratory illnesses and allergies.

It is crucial to protect the health of those in the building by making sure the air inside is as clean as possible. Secondly, cleaning the ducts and other elements of the HVAC system may improve its efficiency, leading to lower energy bills and a longer service life. Not only does this save money, but it also reduces the environmental impact of the building.

What are the risks if I don't get my systems cleaned and inspected?

Kitchen extract, canopy and ductwork systems are highly susceptible to the accumulation of oil and grease deposits and other carbonised debris which, without adequate and regular cleaning, will diminish their performance and effectiveness and could lead to them becoming a fire hazard.

The build-up of oil and grease in a kitchen extract system ductwork can form a hidden combustion load. During the cooking process, flammable vapour is given off from the cooking oils at temperatures between 200 & 300 degrees centigrade. Should these vapours ignite, the fire can spread rapidly through the ductwork, transferring the fire along the way, potentially leading to the fire spreading throughout the entire building.

Aside from the risk of fire, the build-up of oil and grease represents a hygiene hazard which can lead to foul odours and even pest infestation. If the system is not extracting as its full efficiency, then, in some cases, this can lead to an unhygienic “backwash” of air into the cooking area.

With this and other commercial hygiene laws and regulations, such as the Food Safety Act 1990 and Health and Safety at Work Act 1974, subject to regular enforcement, it is essential that businesses possessing these systems ensure they are cleaned to TR-19 standards on a regular basis.

How often should kitchen extraction systems get cleaned?

The intervals between cleaning vary according to duty and deposit (grease) build up. Regular inspections will help determine the required cleaning frequency, however the TR-19 guidelines state the following in the below grid.

Failure to arrange regular cleaning of your extract, canopy and ductwork system may also put you in breach of your insurance policy thus leaving you open to significant financial exposure and, possibly, even prosecution.
