Grease building up inside a kitchen extract system is one of the most common causes of commercial kitchen fires, and one of the least visible.
PTSG Fire Solutions cleans kitchen grease extract systems from canopy to discharge, to TR19 Grease, with directly employed engineers and full pre- and post-clean documentation for your insurer and your fire risk assessment.
What is grease extract ductwork cleaning?
Every commercial kitchen extract system draws grease-laden air through the canopy, filters, fan and ductwork. Over time, grease deposits build up on internal surfaces where they are out of sight, and in a fire they act as fuel, carrying flames rapidly through the ductwork and into other parts of the building.
TR19 Grease, published by BESA, is the industry specification for cleaning kitchen extract systems. It sets cleaning frequencies based on hours of use, and measurable limits for grease deposit thickness. Most buildings insurers now require evidence of cleaning to TR19 Grease, and a documented programme is the accepted way to show that the fire risk is being controlled.

Frequently Asked Questions
TR19 Grease sets frequency by hours of use: typically every 12 months for light use (up to 6 hours a day), every 6 months for moderate use (6 to 12 hours a day) and every 3 months for heavy use (12 to 16 hours a day). Your insurer may set its own requirements.
No. Canopy and filter cleaning by kitchen staff is important day to day, but the grease that presents the greatest fire risk builds up inside the ductwork and fan. TR19 Grease requires the whole system to be cleaned and verified.
Inaccessible sections are one of the most common reasons kitchen extract systems fail to meet TR19 Grease. PTSG can install access panels during the clean, and the report will record any areas that could not be cleaned so you have a clear picture of the system.
