Healthy Food, Healthy Ductwork

Air and Water Hygiene Services for Hospitals: Part Four

by Martin Hembling, Commercial Director, Swiftclean

Hospital kitchens and catering services help to support patient care. Every day, thousands of meals are prepared across the NHS, often in high-capacity catering facilities that run from early morning to late evening. With such heavy use, one of the most overlooked – yet critical – areas of maintenance is that of kitchen extract fire safety cleaning.

Greasy ductwork represents a serious fire risk, and a pressing compliance issue. In the context of healthcare, where patients may be more vulnerable and less mobile, fire prevention is crucial, so ductwork cleaning can genuinely make the difference between life and death.

Hospital catering environments differ from commercial kitchens in several important ways:

High meal volumes create significant grease and particulate accumulations
Continuous operation limits downtime for deep cleaning
Proximity to clinical areas demands higher hygiene standards
Fire safety requirements are stricter due to patient evacuation challenges

Regardless of how healthy the menu may be, grease deposits in ductwork can quickly become a fire hazard, providing fuel for rapid fire spread through the ventilation system. Additionally, poor extraction can affect indoor air quality, staff comfort, and overall kitchen performance.

Kitchen Extract Cleaning Compliance in Hospitals

There are a number of key areas in which hospital estates teams must ensure compliance.

The key UK specification with which every commercial kitchen must comply is TR19® Grease issued by BESA. This specification – and its predecessors – has been co-authored by Swiftclean as industry experts from its earliest inception.

TR19® Grease outlines:

Cleaning frequency
Inspection points
Access requirements
Reporting and post-clean verification requirements

TR19® Grease contains helpful tables which estates management teams can refer to when establishing routines for expert cleaning of kitchen extract ductwork.

Our planning team work with hospital estates teams to minimise downtime in the kitchen and avoid disruption to hospital routines. All our technicians are DBS checked to help ensure patient safety, and trained to industry standards to perform cleaning work competently and professionally.

Appoint a Ductwork Cleaning Specialist

This is one task that is best handled by specialists as it involves cleaning every part of the kitchen extraction system, including canopies, filters, risers, fans and motors, as well as every part of the interior surface of the ductwork itself. When
