Hi Kevin,
We have been guided by the manufacturer in relation to wait times prior
to rooms being available for occupancy. These have been verified with
the use of a hydrogen peroxide meter that records as low as 1ppm.
Kind Regards,

How are you monitoring Hydrogen Peroxide levels in the room after
disinfection ?
In Europe
The SWL (Safe Working Limit) for Hydrogen peroxide is 1ppm for a (TWA)
Time Weighted Average 8 hour exposure over a 24 hour period.
The STEL (Short Term Exposure Limit) is 2ppm for 15 minutes with a
maximum of 4 exposures in a 24 hour period.
The Safe Work Australia standards
(http://www.safeworkaustralia.gov.au/sites/SWA/AboutSafeWorkAustralia/Wh
atWeDo/Publications/Documents/237/AdoptedNationalExposureStandardsAtmosp
hericContaminants_NOHSC1003-1995_PDF.pdf)
Have set the TWA limit at 1ppm with no STEL established
As Hydrogen Peroxide is odourless and colourless it is extremely
difficult to detect at lower concentration levels ( < 5ppm) which would
be well above the SWL or even the European STEL. This is especially
important in rooms with porous surfaces which will outgas for some time
and particularly so as patients are in these rooms for 24 hours a day.
Regards
Kevin

Hi Nicky,
We use a combination of disinfectants for isolation patients depending
on why the patient is in isolation, what sort of clean (daily or
terminal) and what sort of room it is they are in.
Where possible we use a hydrogen peroxide disinfectant for terminal
cleans of infectious patient rooms, if not (e.g. an open room) it is
either bleach or triclosan. I have had reports from our Cleaning
Manager the staff are really on board with hydrogen peroxide
disinfection as their chemical exposure has been reduced.
Kind Regards,

Hi All,
We currently follow the Australian Guidelines for the Prevention and
Control of Infection in Healthcare Guidelines regarding cleaning
schedules, using a detergent for most surfaces and a TGA – registered
disinfectant with label claims specifying its effectiveness against
specific infectious organisms for isolation rooms.
My question is the hospital is wishing to switch to a bleach product for
the purposes of isolation rooms can anyone offer any evidence for or
against a bleach product to assist me in my discussions, one of my
concerns is the aspect of OH&S when using bleach regularly.
Thank you for your responses in advance.
Kind Regards
