What Is Kitchen Extraction Ducting?

kitchen extraction ducting is the metal tubing that connects commercial kitchen extractor canopies to their extractor fans and channels them to the outside of the building taking the shortest route possible. Its primary function is to suck out the unwanted steam, fumes and grease particles produced during cooking processes to prevent them causing discomfort to staff or customers in the premises.

However, if the system becomes blocked due to a build-up of grease and oil deposits it can become combustible and fire hazard with disastrous consequences if a fire ignites in the ductwork. This includes the potential for property damage, loss of life and even prosecution under the Regulatory Reform (Fire Safety) Order 2005 where the death of an employee or customer can be attributed to poorly maintained kitchen extraction ducting.

The Role of Extraction Ducts in Kitchen Ventilation Systems

The fire resistance of the ductwork depends on how and where it is constructed. The ductwork that exhausts directly to atmosphere from the kitchen compartment is usually constructed of a fire-rated material or has been protected by a fire-resistant coating. Ductwork that runs into the roof or wall of the building may not be fire-rated and will need to pass regular inspections to ensure that it is not a fire risk, especially if it passes through other areas within the business where a fire could cause significant harm to people.

All extraction ducting must be accessible for cleaning and inspection purposes at all times to ensure that any blockages can be cleared promptly. Regular professional duct cleaning will help minimise the risk of fire in the ductwork and improve ventilation efficiency.
