Extraction ductwork is often out of sight and out of mind but it is one of the most dangerous fire risk areas in a commercial kitchen.

As grease laden vapours pass through the extraction system they condense on the internal surfaces of the ductwork. Over time these deposits thicken and become highly flammable.

If a fire occurs within the kitchen or canopy area flames can be drawn into the ductwork where grease deposits ignite. Fires within ducting can spread rapidly through buildings particularly in systems that run vertically through multiple floors.

Many serious kitchen fires are exacerbated by contaminated ductwork that has not been cleaned properly.

Professional ductwork cleaning removes this hidden fuel source and significantly reduces fire risk.

TR19 Grease guidance defines acceptable grease levels within ductwork and provides a framework for inspection and cleaning.

Relying on surface cleaning alone leaves businesses exposed to serious risk.

Regular professional extraction ductwork cleaning supported by clear documentation is essential for fire safety and compliance.
