The B&ES TR19 Guide to Good Practice* recommends regular specialist cleaning of kitchen extract systems based on usage. For insurance purposes, adherence to the guidelines can serve as verification that the ventilation system has been properly cleaned and well maintained.

At a recent seminar a fire authority representative stated "Uncleaned grease extract ventilation systems present probably the greatest potential fire risk in buildings with catering facilities".

Insurers require that a fire risk assessment has been carried out and that evidence is available to show that the grease extractor systems have been inspected or cleaned by a professional contractor at the appropriate intervals, as recommended by HVCA, BSRIA and ABI.

Kitchen Extract Cleaning TR19

Over time, the internal surfaces of the ventilation system in a commercial kitchen will become lined with grease deposits. If the kitchen extract ventilation surfaces are not cleaned regularly then this presents an increased health risk, not only from the odours and bacteria but also through the increased risk of fire.

The B&ES TR19 Guide to Good Practice - Internal Cleanliness of Ventilation Systems is a comprehensive guide to the internal cleanliness of ventilation systems. It is vital for specifiers, consultants and facilities managers who need to ensure ventilation systems are properly maintained. TR19 provides the highest standards of best practice and provides a method of verification for insurance purposes that the ventilation system in a building is clean and well maintained.

Here are the recommended cleaning cycles for kitchen extraction systems:

 

Level of grease production	Example	Up to 6 hours	6-12 hours	12-16 hours	16+ hours
Low	No significant production of grease laden air	12 months	12 months	6 months	6 months
Medium	Moderate production of grease laden air	12 months	6 months	4 months	3 months
High	Heavy production of grease laden air	6 months	3 months	2 months	2 months
