Hi Gerard
If you are including negative pressure you should really have HEPA filters on the EXHAUST side of the room air handling, before circulation through the rest of the building. Not on air inlets. This is to minimise risk of dispersal of TB through the air handling system, which is a real possibility. The engineers may be factoring this in as part of negative pressure, but you should probably check.
Cheers
Michael

Oh yes, Michael…
We’ve factored in negative pressure for the new room as we’ve seen a rise in potential TB cases coming in for bronchoscopies in recent times.

Hi Gerard
Dont forget to factor in the usages of the room, both now and in the foreseeable future. I think the facilities guidelines are assuming upper and lower gastrointestinal endoscopy for the air handling recommendation. If bronchoscopy is being performed, you should consider the need for negative ventilation and HEPA filtration, as per Lesley Lewis reply.
Cheers

Subject: Re: Endoscopy and HEPA filtration
Thanks, Glenys.
The links you’d forwarded have been most helpful.
We’re looking to build a new endoscopy room and HEPA filtration was something that we didn’t see a need for, but we were informed by the architects that new endoscopy rooms built these days factor that in and they were convinced that it was a requirement.
Good to know that the filter efficiency requirements are “G4 – F8”, so our stand remains.
Cheers,
Gerald

Hi Gerald,
Heap filters for the ventilation system in Endoscopy Units is not a requirement in the Department of Human Services Victoria, Design guidelines for hospitals and day procedure centres
http://www.healthdesign.com.au/vic.dghdp/
In the full version of the Guidelines see the table VENTILATION REQUIREMENTS FOR AREAS AFFECTING PATIENT CARE HOSPITALS AND OUTPATIENT FACILITIES in Part E – Building Services and Environmental Design Enclosure E1a on page 47 and 48 link below
http://www.healthdesign.com.au/vic.dghdp/dghdp_content/guidelines/dghdp_design_guidelines_complete.pdf
Table states the following:
Endoscopy Unit – Filter efficiency – G4 – F8 2
Table Foot notes
2. Filtration Efficiency: First filter listed is the prefilter if two filters are listed, second is the main filter and the HEPA if listed is the final terminal filter
Is the concern or query related to laser plume?
regards

Dear all,
Are there any IC guidelines referring to the need for HEPA filtration in Endoscopy procedure rooms?
Kind regards,
