This week, Warren Moir is going to show us how to prevent a mould outbreak in a library.
Finally we looked at how to remove mould from library books. New life restorations tv
presents disaster recovery tips one on one where we’d look into how to recover from
disasters such as water damage, fire damage and mould. Here is your host Warren Moir.
Ok tips on how to manage mould on libraries, so it’s not possible to have a mould free
environment what we’re looking for is a normal mould ecology that way we can keep
it in check and whatever is going on is quite normal so the only dependable way to
do this is first number one, have your relative humidity in the library around of that 50%.
Not getting any higher than this will control the moisture in the air then therefore there
shouldn’t be a dewpoint problem as the temperature drops overnight or whenever.
So have a good clean air, and a good positive circulation of air at the place and scrutinizing books
as they’re returned to make sure they’re clean and appear to be mould free or run
a HEPA vacuum before they get back on the storage and you’d also had to have regular maintenance
program through the building, a monthly inspection say, look at the air conditioner make sure
the filters are okay, there’s no dust build up on the air conditioner ducts and sheets,
and this way we’re just checking as where the air flows out or the return point from
the air conditioning and obviously always be on the lookout for water leaks.
Have yourself an emergency program something you can put into place if there’s a problem
and it’s gets out of control that you’d want to ring the likes of us to come and help
you out and manage the situation or help to get it back to normal humidity levels be it
through the humidifications or extra air movement. For level 1 PPE, get at least a P2 mask on
and something to handle the books and cover our hands, but that will be level 1, if we
are in the level 4 environment or level 3, we’ll then have a full face mask on, proper
gloves, full suited up and taped at the joints as per Australian mould guidelines. Let me
explain a little bit about New life restorations HEPA vacuum bench, we have a underneath a
HEPA filter which continually draws air through our work platform at the top so any spilled
particulate matter will go straight down into that, and we have here a HEPA vacuum cleaner
for sucking down the surface of the books, so we'll just turn it on now, and let me
demonstrate that there is a vacuum going on, let’s hold a piece of paper and you can see it will
see it sucks it straight down, so thats indicating the air goes straight down through under the
filter so we pick a book up, just hold it over an area, and we’ll just vacuum, HEPA
with a horse hair brush over the whole surface of that book so any mould spores that are
sitting on it, so we got now a book that’s clean and it’s back to normal mould ecology
and ready to go the next stage of the restoration
The place it’s where is most likely would be used is inside an environment in a library
where we can actually wheel the unit between the isle ways. Its wide enough to fit.
and we can take the books off the shelves lay them on the side in the correct order. We can deal them over
this as stage as our one treatment area of HEPA vacuuming off the other side then catalogued and then box then
taken offsite if we need to get in stage 2 of the mould remediation.
