Three duct types
A hospital laundry is doubly regulated - the linen is decontaminated under HTM 01-04, and the ventilation serving it falls under healthcare standards. Cleaning the ductwork is an infection-control job as much as a fire one.
The short answer
A hospital laundry handles a different problem from a hotel or care home. On top of the fire risk that any high-volume laundry carries, it processes used and potentially infected linen, and it sits inside a building where vulnerable patients are protected by strict infection control. That puts its ductwork under two regimes at once - the rules for decontaminating the linen, and the standards for cleaning healthcare ventilation - and cleaning it has to respect both.
The linen and the standards
The linen itself is governed by HTM 01-04, the health service memorandum on decontamination of linen for health and social care, which implements the biocontamination-control standard BS EN 14065 and replaced the older HSG(95)18 arrangements for used and infected linen. Used, soiled and infected linen is segregated, bagged and thermally disinfected under that framework so it does not carry infection onward. That is the laundry process - but the ventilation and dryer ductwork serving it is the other half of the picture.
Healthcare ventilation falls under HTM 03-01, which sets how hospital air systems are managed and maintained and references the TR19 Air and BS EN 15780 cleanliness standards for ductwork. In a hospital, clean ductwork is not only about airflow and fire - it is part of controlling the airborne spread of infection, which is why the Care Quality Commission takes an interest in it.
Cleaning without spreading contamination
The critical difference in a hospital is how the ductwork is cleaned. Disturbing debris inside a healthcare ventilation system releases dust that may carry microbiological contamination, and letting that loose in an occupied hospital is exactly the risk infection control exists to prevent. So the work is contained: sections of ductwork are isolated and zoned, placed under negative pressure through a HEPA-filtered negative-air unit, so contaminants are captured at the point of cleaning and previously cleaned sections are not re-contaminated.
This lets the work happen in a live, occupied facility without cross-contaminating wards, theatres or circulation spaces. It is slower and more disciplined than a commercial clean, with documentation to match - and in a hospital that discipline is the job, not an add-on.
What it means in practice
In practice a hospital laundry needs the same lint and airflow discipline as any laundry - the exhaust cleared so drying works and the fire risk stays down - but delivered inside a healthcare containment regime. That means isolating and zoning the run, HEPA-filtered negative-air capture, care not to disturb debris into occupied areas, and records that satisfy infection-control and CQC expectations. The fire hazard is the same physics as elsewhere; what changes is that in a hospital you cannot solve it by simply blowing the duct clear. It is the one setting where how you clean matters as much as that you clean.

Under containment. Sections are isolated and zoned under negative pressure through a HEPA-filtered negative-air unit, so debris that may carry contamination is captured rather than released into occupied areas.
Yes - the lint and airflow physics are the same as any laundry. The difference is that in a hospital it must be handled inside a healthcare containment regime, with records to match.
