Hospital Fume Cupboard Testing & Maintenance
Pathology, histology and mortuary containment for NHS and private hospitals, maintained without interrupting diagnostic work.
Why healthcare is different
There is no holiday window, and the chemistry is unusually specific
A school can shut a laboratory for a fortnight. A pathology department cannot. Diagnostic work is continuous and specimens do not wait, so equipment has to be maintained around a service that never stops — unit by unit, in agreed slots, with the department still functioning.
The chemistry is narrower than in a research setting but harder on filtration. Histology and pathology work is dominated by formaldehyde and glutaraldehyde, which general purpose carbon has little capacity for. Ductless units in these departments need media formulated to oxidise those specific fumes, and it is the single most common specification error we find.
Then there is access. Hospital estates run permits to work, infection control requirements and induction procedures, and a contractor who does not understand that wastes a morning at the door.
Formaldehyde-grade filtration
Media formulated to oxidise formaldehyde and glutaraldehyde fumes, not general purpose carbon. Filters
Unit-by-unit scheduling
The department keeps working. We take one cupboard at a time, in slots you set.
Permits and induction
Directly employed engineers, so the same people complete your induction rather than a new contractor each visit.
DBS checked
Every engineer, as standard, for work in occupied clinical buildings.

Compliance
Formaldehyde makes this a COSHH problem with a short fuse
COSHH Regulation 9 requires engineering controls to be examined and tested at intervals of no more than 14 months. In histology and pathology that duty carries more weight than the interval suggests, because the substances in routine daily use are ones with tightly controlled exposure limits.
On a ducted cupboard that means airflow and containment. On a ductless one it means the filter is the control measure, and a saturated formaldehyde filter is not something anybody notices until people start reporting the smell.
Testing is to BS EN 14175, with HSG258 and BS 7989 applied to extract and LEV systems.
Healthcare FAQs

Yes. We work through the units one at a time in slots you agree, so only the cupboard being tested is out of use. A whole pathology department can normally be covered without losing service.
On a recirculating unit, an odour should be treated as filter breakthrough — take it out of use and call us before it is used again. It is also worth checking the media grade: general purpose carbon has little capacity for formaldehyde, so the wrong filter may have been fitted at some point.
Yes. Send us the requirements with the enquiry rather than on the day. Our engineers are directly employed, so once inducted they are the same people who return each visit.
