In July 2019, another new specification was published regarding the Fire Risk Management of Grease Accumulation Within Kitchen Extract Systems. Know as TR/19 Grease, this has been created to improve compliance standards with regards to kitchen extract fire safety cleaning.
TR/19 Grease has been developed from the updated TR/19 specification because some contractors were failing to follow this guidance properly, and in some cases, completely ignored it. This resulted in grease deposits in ductwork that clients were led to believe was clean and compliant; fires in ducts which resulted in significant fire damage; and kitchen operators losing their insurance, despite believing that their cleaning contractor had carried out a compliant job.
TR/19 Grease ensures that these problems don’t continue by placing more emphasis on controlling fire risks from build-ups of grease in kitchen extract systems. Contractors are now required to follow the specification in order to work in the industry.
At Pro-Duct Clean, we’ve always stuck to the guides to good practice regarding TR/19 and other specifications from the very beginning, before they were made to be mandatory specifications. We pride ourselves on always providing our customers with the very best standards of duct and kitchen extract system cleaning.
If your kitchen extract system needs essential cleaning, get in touch with us today for a job done right.
Intervals between regular specialist cleans depend on usage. These are minimum recommended intervals according to the BESA’s TR/19 best practice guidance
1) Grease extract systems MUST be regularly inspected and cleaned to remove any fire hazards.
2) Health & Safety Executive, BSRIA and FPA Insurance ALL stipulate that kitchen extract systems should be kept clean to minimise fire risks.
A new table provides clearer guidance to assist in assessing the requirements for cleaning particularly where cooking methods produce high volumes of airborne grease contaminants.
|Example||Up to 6 hrs per day||6 to 12 hrs
||12 to 16 hrs
||16 + hrs
||Max inspection interval|
|No significant production of grease||12 months||12 months||6 months||6 months||6 months|
|Moderate production of grease laden aerosols during normal daily food production||12 months||6 months||4 months||3 months||6 months|
|Heavy , significant production of grease during normal food production||6 months||3 months||3 months||2 months||6 months|
The Building and Engineering Services Association has recently updated the “Guide to good practice – internal ventilation systems” [TR19]. It is almost 10 years since the previous update, and in that time we have seen ever more stringent levels of ventilation-system, cleanliness being required.
There are two key factors driving this requirement;
Read more about this in an article by Richard Norman, Chairman of the ventilation hygiene branch of B&ES.
Here is a bit of background to the standard which you may find helpful.
In 2005 the then HVCA (now known as BESA) amalgamated two publications (TR/17 and DW/TM2) to produce the TR/19, which incorporates the best practice for installing new systems and maintaining them and allows specifiers to deal with all aspects of the duct system in one publication.
TR/19 is ideal for use by specifiers, consultants and building legislators to ensure that ventilation systems are properly maintained. It is especially important for kitchen ventilation due to the elevated risk of grease deposits in extract systems, which can lead to fires. Adherence to the standards in TR/19 will provide detailed, recognised proof that the ventilation system in a building is safe and well maintained, which is vital for securing insurance policies.
The guide includes further improvements to best practice standards with particular reference to kitchen extract systems. According to Gareth Keller, Head of the Heating Ventilating Contractors’ Association’s Specialist Group Services department: “As the bar for indoor air quality standards is raised, the industry is actively seeking guidance.
TR/19 draws on the extensive experience of BESA members and has been written to meet this need, providing high-level best practice advice.” He continued: “Research shows we spend an average of 90 percent of our lives indoors, consuming almost 25,000 litres of air a day each. Lower work performance is frequently symptomatic of poor indoor air quality in offices and schools, and asthma and allergies are more prevalent than ever.
Everyone has the right to healthy indoor air. Therefore, it is vital we do everything in our power to ensure optimum indoor air quality. The proper maintenance of ductwork and ventilation systems is paramount in this and I am positive that the guidance in TR/19 will provide a great resource for the industry at this important time.”
