I use this respirator for everything I do, climbing in the attic,
brushing floor polyurethane, etc, obviously is not correct. Even
though, it blocked the smell of solvent all the time.

I know polyurethane has isocyanates which is bad stuff and you need an
expensive setup to protect from it, does risk still exist if you brush
it?

I recently got a spray gun and I was planning to finish a mantel trim
kit with polyurethane.. I probably will be spraying laquer, enamel
etc for certain projects. I think it's time to educate myself better
and get a proper mask / respirator for paint.

Can someone tell me what kind of respirator should I get in what
situation? When do I use P100 and when do I use organic vapor etc
etc?


Thanks!!

Look in the Yellow Pages for a safety supply store. They'll
sell what you need and have the expertise to tell you
exactly what the gear does, and how to properly fit it.

For painting, I have used this type mask for several years:

For general shop use I like these:

A Sherwin Williams store will have a selection of respirators and
cartridges for whatever you will be doing, and unlike a big box store,
the sales staff will be able to answer your questions without guessing
or reading the package.

Maybe, maybe not. I've seen both ends of the spectrum in the same local
Sherwin Williams location.

If the local SW store is like my local store, other suggestions include
Homestead Finishing, Grainger and local places listed in the Yellow
Pages under "Industrial Safety Equipment and Supplies."

Another suggestion:

Don't skimp on the quality of safety gear. Poor gear gives a dangerous
and false sense of security.

Jamestown Distributors will have 3M.

The 6800 is the top of the line.

After that, it is the self contained units that have the air tank
strapped on your back.(Sometimes on ebay)

I've been to a number of SW stores and I've never encountered a no-
nothing clerk of the HD "associate" caliber. I've had times where the
SW clerk would not know the answer to my question and point me to the
store manager standing 20 feet away. Not sure what the deal is with
your area, but around here it's primarily a professionals' store and
there's none of the selling you a bill of goods just to make a sale.
In any event, all of the respirators are hanging on the wall and they
have a good selection of cartridges.

Last time I tried to research this I could find no guidance as to how long
the filter cartridges for respirators were supposed to last. IIRC this
search included labels, packaging and the manufacturer's Web site. Anyone
knowledgeable about replacement frequency ?

If you're talking dust filters, they need to be replaced when you have
trouble sucking air through them.

Nope, paint/solvent fume filter cartridges.

Conventional wisdom is that when you can smell the solvents it's time to
replace the cartridges.

If you have the facilities to collect air samples and analyze them, then
it might be possible to work out a schedule.

Remember, no cartridge respirator provides protection from the
isocyanates in polyurethane

A few years ago, I knew the 22 year old geography-major manager of the
Wallingford, CT store, not the same store as above, because I mixed his

Can we trade stores? I'll pay shipping. G

Polyurethane does not contain isocyanates. If it did the only acceptable
respirator would be an air supplied one. None of the filter type can do the
job. JG

If you're in CT and want advice on a respirator, try Industrial Safety
Supply,http://www.industrialsafety.com/index.html.

For finishes for woodworking, by the way, it may be worth a trip to
Springfield--Clark Paint Company is an ML Campbell dealer with prices
about half what I see online (at least on what I've gotten there--don't
know if I hit a sale or if it's across the board) and they do know their
stuff, and within about 5 minutes of them are a Woodcraft, a Sherwin
Williams Automotive store (not particularly interesting place to browse,
but ask and if it bears some reasonable relation to automotive finishing
ye shall likely receive), a Sherwin Williams Professional store (has
their 2K stuff and the like that you don't fine at the consumer stores),
and probably a lot else that I haven't found yet. Warning though--this
is all a few blocks from the fairgrounds--when the Big E is on traffic
is a bitch.
