Subject: Silica Dust in studio
I would please like to know what other potters do about clay dust in their
studios. I am not talking about clouds of dust but light dust that just
lightly settles around. No matter how much you clean with water etc. there
always seems to be a light film of dust which you can wipe of with your
finger.
I was wondering if there is any type of filter system that removes particles
that might be airborne. Maybe someone has information or experience with
this issue.

Bruce,
Hamilton Beach has a HEPA room air filter that Catherine and I bought (for a
reduced price) in an outlet store several months ago. It is Model 04163 and
will work on rooms up to 350 sq/ft. We got the automatic model which
changes the speed of the filtration fan dependent on the amount of dust in
the air. We paid about $130 for it. Wal Mart here has a different unit
which filters to a lesser amount - still HEPA - than ours which 99.97%
effective for particles down to 0.3 microns. Even though we have an
unfinished, rough garage floor (that we clean using a RIDGID wet/dry vac
with a HEPA filter), we have noticed a difference. Hamilton Beach's
website for these filters is http://www.trueair.com/index.html Possibly
one of these will be just what you need.

I live in the desert. Even if I never touched
clay, everything would be covered with a light
coating of dust - that's life on Planet Earth.
(Earth = Dirt, remember?) I don't worry much
about it.

Bruce,
There is a filter system......... actually a pair of filters.......... yo=
ur
lungs . They work pretty well for sub-micron particles.
Cleaning up with water AFTERWARD is not the place to go on this problem. =
What you need to do is try to identify what exactly it is that you do in
your studio that seems to get the dust into the air in the first place. =
Cleaning with water is only a PART of good studio practice in managing
dust.
The prime line of defense for airborne contaminants is to prevent them fr=
om
getting airborne in the first place. This involves identifying the sourc=
es
and then either providing adequate LOCAL ventilation to pick them up, or
changing the work practices to decrease or eliminate the dust. Obviously=
the dust is getting into the air......... you are seeing the tangible
results in the morning.
So what you likely would want to do, in order, is........
Identify the dust sources in the studio
Change dust producing working procedures that can be easily adjusted
Provide local pickup ventilation for easily identified point sources that=
can't be changed
Eliminate or contract out high dust producing point source activities for=
which you cannot provide adequate local ventilation
Provide general dilution ventilation for diffuse dust sources that can't =
be
contained or changed
Install appropriately designed general air filtration =
Seal yourself in a giant Ziploc Baggie .
Many "habits" we have developed in our working serve to get dust into the=
air....and we don't even notice them. Most are done pretty
unconsciously.......... Dusting off a spot on a table with a a flick of a=
hand before working. Blowing off a little area that we have just smoothe=
d
on a dry, bisqued, or glazed piece. Shaking out a piece of canvas before=
using it. Slapping our hands against the thighs of our dry clay covered
pants or onto a clay covered apron. Dropping a bat or a board onto a cla=
y
covered surface. The possible list is long. Most of these are diffuse
sources of dust.... and are impossible to control with local pickup
ventilation. These are best addressed by changing work patterns.
Good air filters ARE available...... but they should be the LAST thing yo=
u
utilize after other approches are exhausted..... cause if it is in the
air....... your lungs are getting it along with the air filter.
Will you ever control 100 percent of it....... unlikely. But any effort
you make in this regard will move you TOWARD that totally dust free
air....... and that is a big step in improving your working environment.
Hope this info is of help. Like always.... check the archives... there h=
as
been a LOT discussed on this subject in the past.
Best,

Hi Bruce,
That fine dust is airbourne clay and silica etc. - John Baymore is right -
any thing you do in a pottery studio raises dust - and if you have hot or
cold air heating or cooling - every time the fan comes on the dust is
disturbed. Best to minimize dust making - keep the floors and working
surfaces clean and think about what you are doing - even glaze on the floor
will add to the problem.
My best advice is to get a central vac system which will put all dust
outside as you clean.
When doing dusty work go outside or use the vac system to collect the dust
as you work.
As John said - not much sense in finding out when you are 60 that you have
been removing the dust with your lungs -.

Less is more in this case - especially if you live in a dusty place. I do
agree that the worrying is sometime worse than the danger - best to do
something about it - RR
