TR19 Guidelines

TR19 is a set of best practice guidelines created by BESA (Building Engineering Services Association), as a way to standardise extract and duct cleaning. Originally introduced in 2005, BESA published a new, stand-alone standard document ‘Fire Risk Management of Grease Accumulation within Kitchen Extraction Systems’ in July 2019 with more detailed specifications and criteria that must be met by a service provider in order to provide a TR19 compliant kitchen ventilation and duct cleaning, to help reduce the growing number of commercial kitchen fires:

“Commercial kitchens have grown in number over recent years and fires within premises involving commercial kitchen extract systems as either a source or contributing factor to the fire has focused the attention of insurers, property owners and landlords, ensuring that kitchen extraction systems are correctly cleaned and maintained.”

With this in mind TR19 Grease - Fire Risk Management of Grease Accumulation within Kitchen Extraction Systems, has been produced as a specification document in its own right for the first time in 2019. The risk of fire from the build-up of grease deposits in kitchen extract systems and the expectations of building occupiers and legislators has resulted in an ever more stringent level of ventilation system cleanliness being required.”

Why are the TR19 Guidelines Important?

The accumulation of grease within extraction systems and ducting can diminish airflow and increase the risk of fire. TR19 is a recognised standard for measuring grease levels and identifying recommended cleaning frequencies, which are designed to reduce the risk of fire and are tailored to your system. Regularly clearing grease deposits can promote a good working environment by taking away heat from cooking to maintain a good supply of airflow and reduce the risk of kitchen fires.

Under the Regulatory Reform (Fire Safety Order 2005) and equivalent national cleaning legislation in Scotland and Northern Ireland, a requirement is placed on the ‘responsible person’ (owner, occupier or person with control) to make sure action is taken to prevent fires, which includes a ‘suitable and sufficient’ Fire Risk Assessment. Due to the high risk of potential fire, kitchen extraction systems warrant very close attention and best practise set out in BESA’s TR19 guidelines should inform this assessment, to help ensure that the extraction system in your commercial kitchen remains safe at all times.

Additionally, many insurance policies contain conditions relating to cleaning regimes kitchen extraction systems and if a fire occurs which is shown to be associated with inadequate cleaning of ductwork,  then it could jeopardise your right to indemnity for loss or damage.

Is My Service Provider TR19 Compliant?

Due to the increase in commercial kitchen fires, BESA has detailed criteria that must be met by a service provider to enable them to carry out TR19 compliant cleaning of kitchen ventilation systems. This ensures that companies are providing a high enough standard of cleaning to help reduce the risk of kitchen fires.

You should ask your current service provider the following questions to determine if their service is TR19 compliant:

  • 1. Do you provide a TR19 compliant post-clean report?

  • 2. Are you a part of the Ventilation Hygiene Elite scheme (or equivalent) and therefore have access to the BESCA (Building Engineering Services Competent Assessment) portal, so that reports can be registered and audited?

  • 3. Have all of the technicians carrying out the work completed BESA approved training by a BESA third party approved training provider, to minimum Grease Hygiene Operative level, and hold an in date qualification?

If the answer is NO to any of the above, your service provider may not be providing a TR19 compliant service.

Cleaning in Accordance with the TR19 Guidelines

In the updated document containing the TR19 guidelines, published June 2019, it states that a system must be cleaned to its entirety to be fully TR19 compliant. Whether the system has had a ‘FULL CLEAN’ or a ‘PARTIAL CLEAN’ will be stated on the Hygiene Certificate generated by the service provider in the BESCA portal. Our technicians insert access panels every 2m in accordance with the TR19 guidelines, although this may not always be suitable. Therefore, Rentokil Specialist Hygiene has invested in remote brushing equipment to help ensure that we are able to clean systems to their entirety.
