Mel I hope you post this - It may save sombody. Here goes - Personally I think that Vince is WRONG!!!!!!!. WEAR A MASK!!!! He might be right in some areas (?) but not this one. This is from a person who is suffering from COPD (chronic oxygen - pulmonary disease). I smoked for a few years, painted with a air brush for many years and did not wear a mask because it fogged up my glasses. Went into pottery and found that spraying many very expensive OSHA "approved" spray booths - but I still caught COPD. Nobody to blame but myself and my vanity - thinking I did not need to be careful. Now I wear a umbilical core (MY IMBECILE cord) of oxygen to sleep (about three hours a night- if I'm lucky), take many medicines - some not so good for the rest of my body, and am generally "trapped" by lack of oxygen. It is not fun to have no energy, can not walk more than 100 feet without stopping for a "breather", Carry oxygen tanks around with you, can't walk up a flight of stairs without stopping,
can't carry more than 10-15 pounds any distance and spend about two hours in the morning "medicine-up" for the day. I was the IMBECILE and I am suffering for it. PLEASE TAKE CARE with your lungs. You don't want to be like me. Sam (Imbecile) in Daly City.

Bob -
It does no good to make such generalizations. A proper spray booth does
protect the operator. There are lots of people around using inferior,
inadequate spraybooths, and even some of the small commercially-made ones
are completely inadequate. The problem is most often in the power and
volume of the exhaust fan, in proportion to the square footage of opening
across the front of the booth. The front opening should not be any larger
than it needs to be for efficient access while spraying.
etc-etc and so on-

Well, thanks for your generosity in saying that I might be right in some
areas. I'm swelling with pride.
But regarding spray booths, your reasoning is flawed. I am certainly an
advocate of wearing dust masks whenever there is any question at all about
dust in the environment, but if you use a spraybooth that requires you to
also wear a dustmask, then you will be putting toxic dust into your
environment every time you use your spraybooth, and any air currents will
lift them into the air later on, when you are not wearing a dust mask,
unless you wear one all the time.
The ENTIRE REASON for a spray booth is to exhaust ALL of the contaminants,
and if the spray booth doesn't do that, it is pretty worthless. So rather
than telling people to wear a dust mask when using a spraybooth, we should
be telling them to make sure that their spray booths work properly, as I
explained in my post. Does that make sense?

Vince - Thank you for your response. You are the Clay expert and I value your messages and expertise. However in this case you have your opinion, I have mine and I stick by it. I had several OSHA approved spray booths and did not always wear a mask (when air brusning especially. I hope that NOBODY else ever gets COPD.
P.S. if painting, a dust mask does not protect you from chemicals/vapors You need a Good paint type mask and change the filters .Regards, Sam in Daly City

This discussion is really getting out of hand. Spray booths may exhaust
some of the bad stuff, but when you spray for several hours, there are times
when, dried glaze from implements, the dust from your hands from handling
sprayed pots etc. release harmful substances into the air. The HVLP sprayer
I now use, produces large droplets and they pose no threat, but the dried
glaze on the exhaust filter can get loosened and pose a danger. I hate using
a NIOSH mask and sometimes use a medical type mask. I now believe this type
of mask to be ineffective for small particles. I don't care if the spray
booth passes the Pitelka tests or not, you need the protection when working
with substances that produce the harmful particles.
I had my say and I'm, done.

Donald -
The discussion is getting out of hand? I am not sure what you are referring
to. This has been a pretty tame and sensible discussion, and it seems to be
resolving in a very reasonable way. Did you see my post the day before
yesterday where I agreed with Dave Finkelnburg that even if the spray booth
passes the standard test, it is still a good idea to wear a respirator?
That does seem like common sense, although it is also common sense to make
sure that all dust and overspray go into the spraybooth.
If you think that any appreciable amount of overspray is getting on your
clothing, then one sensible solution would be to wear an old shirt while
spraying, and then go outside when you are done, take off the shirt, and
shake it out downwind very thoroughly (wearing your respirator, of course).
It is always difficult to know how far to go. Of course we want to avoid
breathing ceramic particulates under all circumstances, but no one wants to
wear a respirator all the time. So a major part of maintaining lung health
is in minimizing the degree to which ceramic particulates contaminating the
studio, where they might be lifted into the air later on when we are not
wearing a dust mask. That is what I am trying to address here.
If you are spraying for several hours, then you obviously have to go to
extra effort each time to make sure that none of that residual dust from
your implements or clothing contaminates the studio.
