Advice on Isocynates
Richard Medway
give a long field life in outside weather. This is a decision already
taken by boss, so presently unegotiable. The quantity I'll be using is
in cups, not gallons, the most about one quart at a time, for three or
four occasions per year.
As you can anticipate, as for most small businesses, we are trying to
do this on the cheap, so presently I'm making do with a good
respirator with organic vapour filters, and changing the filters for
each painting session.
I've recently downloaded a ton of stuff telling me this is slow
suicide, and i should be using an air-line system with a full face
mask. As many may know, this is an expensive way to go.
Questions, is my present protection enough, given my level of
exposure? If i go to an air-line system, I have read an official
report from Sascatchewen govt which says you can use an ordinary
oil-less air compressor, 4-6 CFM, as long as you install proper
filters to cut out oil products and overheating.I have a post from a
while back on dangers of oil and overheating, which I intend to take
seriously, but since I'm only using it for half-hour sessions, will
this level of equipment be sufficient? I'd love to say to powers that
be that I can't do it unless you pay $1000 for the correct equipment,
but this probably wouldn't fly. Any good source of cheap systems, from
spray companies going out of business?
Thanks for any advice

Who's we? Your boss and the undertaker? What's your share in this after you
punch out at the end of the day? Or are you one of those "team players" who
does exactly what an idiot boss tells you to do? Do you live for the company or

Maybe a surreptitious call to Cal-OSHA is in order. Detestable as OSHA may be
in so many things, this is one situation where such an organization can help
the little guy, and when dealing with cheapskate idiot bosses, it may be the
only way somebody farther down on the ladder can get their attention.

==============
REFUSAL TO WORK BECAUSE OF AN UNSAFE WORKPLACE CONDITION
Labor Code Section 6311 provides limited protection for workers who refuse to
work because of an unsafe condition in their workplace. The protection exists
only when both of the following conditions are met:
(1) A worker refuses to perform work because of a violation of a Labor Code
Section or a Title 8 Safety Order; and
(2) The violation in (1) would create a real and apparent hazard to the worker
or his or her fellow workers (an "imminent hazard").
Any worker who is laid off or discharged in violation of Labor Code Section
6311 has a right of action for wages for the time the worker is without work as
a result of the layoff or discharge.
================
Cal/OSHA DISCRIMINATION PROTECTION
Labor Code Section 6310 provides that no person shall be discharged or in any
manner discriminate against any worker because the worker has filed a Cal/OSHA
complaint. Some examples of discrimination are firing, demotion, transfer,
layoff, losing opportunity for overtime or promotion, exclusion from normal
overtime work, assignment to an undesirable shift, denial of benefits such as
sick leave or vacation time, blacklisting with other employers, taking away
company housing, damaging credit at financial institutions and reducing pay or
hours.

It also means that in a worst case, if you are unwilling to use in full the
legal means at your disposal, you have to be willing to walk away from your job
and keep your life, rather than the other way around. Which is the more
desirable solution for you?
Why doesn't the boss just send it out to a shop that can handle this stuff and
throw them a few bucks? Any high-end automotive or aircraft paint shop should
be able to do it. No investment on his part. And for the quanties being used,
your cheapskate might get by with a case of beer for the painter. But don't
count on it.

For the cheapest solution, buy a shop-vac, place it outside, run output
hose inside.
You may need larger hose than you would with a compressor, but there
is no chance of getting significant CO in the output.
Place a hole in the tube at the outside end to reduce flow to something
that's about right, as the flow through the motor has to be enough
to cool it.
Ensure shop-vac is not used for cleanup by disabling the input hose connector.
Run for an hour before first use to get best air.

The product you are using should have a Material safety data sheet (MSDS)
supplied by the manufacturer which should supply information about
appropriate safety equipment to wear.
It should also supply information about what concentrations of the product
are safe to work in (TLV), levels which are immediately dangerous to your
life and health (IDLH), odour threshold value, etc. Most of these are given
in parts per million (PPM), so if you see an IDLH value at say 0.5 PPM you
know that it is going to be a real nasty for you. Thats like evenly
distributing 1/2 a gallon in one million gallons!!
From memory isocyanates have a problem with air filters due to the fact that
the odour threshold (the level at which you can smell isocyanates) is a lot
lower than the level at which they are dangerous to your health. So when
your filter has stopped working and you can smell the isocyanates you are
already in danger. Also filters are negative pressure inside the mask and
can easily leak vapours in - beard growth, face shape, sweat, etc can cause
one to leak very easily.
Before using any air filtering system you should have a smell and taste test
completed - so you know if you can detect a filter which has stopped working
or is leaking.
As for supplied air systems they can be even more dangerous than filters if
you use just a regular air compressor.
My own view would be to get an air tank like the fire brigades or divers
use, have a positive pressure air mask on a long air line so you can work
easily. You might even be able to hire them rather than buy them.

Thats about what the painter we had at the Air Guard base was also,
but only for real. Never would use a mask, for that matter he never
would follow any regulations, and lived on the edge all the time. I
walked into the paint shop (we actually used a fuel cell repair hanger
to paint it, not for ventillation but to have it inside) so lacking
any real paint type use ventilation and fans etc, when I opend the
door, it was just a thick heavy fog of paint vapors, and there setting
on the backbone of the (Was an F-4F that was getting painted) plane
was a barely viseable silloette of a person and a faint glow of a
cigarette....The idiot was inthere smoking while he was painting. It
was lacquar, so it was just as prone to going up as any other paint,
but his theory was if he kept one lit all the time it would be safe as
he would not be introducing a flame in the vapor! He was a very heavy
smoker, drinker and non player when following regulations, and he also
died at age 61, almost exactly one year after attaining mandatory
retirement.......from multiple respiratory problems no less.

knows how to do it than do it yourself.
The data sheets will tell what is required to do the stuff properly.
If all else fails, knowing when you're going to have to do a job and quietly
calling the OSHA people before hand and letting them know this is happening
can often times produce the desired results.
Of course, if you do call OSHA, make sure that your name, etc. aren't
mentioned in any discussions that they do as it may be your job. Many
places they do unannounced inspections of a business and this is what you
want them to act like.

OSHA does have it's good points. They were giving hearing tests here at the
airport where I work a few years back. Parked the so-called
"sound-insulated" truck in front of the airport and in line with D concourse
where all the 767's would taxi in. Of course, it was a joke to try to get a
real hearing test with that ambient noise. After working around jet engines
for so many years, I knew my hearing was getting worse and I wanted
a_real_hearing test. I called OSHA, they did an investigation and things
did happen. Started parking the truck over on the other side of the
airport where we could get an honest hearing test. Made it very inconvenient
for the company to shuttle people over there and back during working hours,
however. Tough. They've got some horsepower.

The belt-pack powered respirators are a reasonable improvement over the
basic respirator. For example the 3M / Racal products at:
http://www.airwareamerica.com/prod04.htm
There are a bunch of options of filter and face shield style.
I occasionally use one of the Airmate hardhat / face shields with a powered
filter for welding fumes and woodworking dust. They appear to reccommend
the BreatheEasy style for organic vapors. In any event it'd be a good idea
to ask them how suitable it is for your application.
As for air-line respirators, I occasionally see new or used components or
complete systems on ebay at a fraction of new price. New, maybe is OK.
As for a used one, with no idea where it's been, reckon I wouldn't be
comfortable breathing through it even with new filters.

They have supplied air breathing systems for as little as $400. Seems
pretty damn cheap compared to possible lung damage to me. Hell, even
if my boss wouldn't pony up for it, I'd buy it myself, and take it home

Lets put it this way, a good friend painted the chassis of his
roadster with this stuff. It didn't seem to bother him that day,
but he nearly died a few days later. He was in the hospital for
3 months, and he still has breathing problems.
He was wearing an organic vapor mask, but it obviously wasn't
doing the job. Your exposures appear to have been lower so far,
but the results of insufficient filtering can be pretty horrible.

I have an air line system with a full coverage helmet (bunny suit too
for that matter). Oil mist in the air stream can cause a particularly nasty
form of pneumonia. Using an oil-less compressor eliminates the oil mist
threat, though you still have to filter for particulates. The carbon vanes
(Gast rotary) or rings (Gast piston type) tend to disintegrate at inappropriate
times. These compressors are noisy and short lived. Using one with an
air line helmet is almost guaranteed to give you a headache.
But it is possible to filter the oil from the air stream of an ordinary shop
compressor. The filters to do that aren't cheap (no, the ordinary filters
used for painting aren't good enough), but they're lots cheaper than
buying a rotary vane compressor for ocasional use. Quieter too.
If you go this way, you should have a CO monitor in the air line because
the heat of compression can generate CO from oil splash getting past
the rings in the compressor. The compressor rings have to be pretty
bad for this to be significant, but how sure are you that the rings in that
old banger shop compressor will still be good the day you breathe this
stuff?
Note that the filtered air will be very dry after passing through the oil
filters, and this is hard on your lungs too. Bubbling the air through a
water trap will moisten the air enough to make it much better to breathe,
also catches any residual oil. This probably isn't very critical, unless
you're going to breathe the air for hours at a time. But it sure adds to
your comfort level, and it is cheap to rig up.

to be entirely suited, taped at any seams. Forced air breathing
apparatus only. Safety person, similarly attired, waits and watches from
outside the booth. Safety person is equipped with an independent self
contained air source.
We have a shower/change room that is the only place we are allowed to
exit the booth to, and pains are taken to ensure that the residue is not
tracked out of the area of the booth.
Skin contact is as bad as breathing the stuff.
Is your boss the kind of guy you would kill yourself to protect? Get
the right gear, different paint, or a new boss.
I think the suggestion that you hand the paint to your boss and let him
have at, is a good one.
I would be very surprised if the environment cops in CA would not have
something to say about this too.

Keep in mind,
NO paint manufacturer recommends a $6 Tyvek "Bunny" suit for water based
enamel house paint. I wonder why.
NO filter manufacturer recommends or has a filter for isocyanates.
Woops, maybe they do, I found this but keep in mind it is not specific
to your paint: http://www.labsafety.com/refinfo/ezfacts/ezf233.htm
Q. Can I wear an air-purifying, cartridge-style respirator for
protection against isocyanates?
A. Yes. Air-purifying respirators can be used with contaminants that
have poor warning properties, such as isocyanates. However, you must
check with hte manufacturerer of your respirator for specifics. For
example: 3M and MSA have a respirator change out formula for some
isocyanates. If you know the airborne concentration in parts per million
(ppm), you can calculate approximately how long a cartridge will last.
From the same page:
Proper respiratory protection against isocyanates requires the use of a
full-face, continuous flow supplied-air respirator or a self-contained
breathing apparatus (SCBA).
Systems with pumps can be found for $400 or a bit less. Systems using
shop air can be had for $250 IIRC, however, that price does not include
a CO detector.
I recommend you read the Effects Of Overexposure, especially the section
on sensitization,,, or as I would say, the second time you paint may
just kill you.

Not if somebody points them at this company. Those OSHA and EPA guys just LIVE

I can't believe that in this litigious society, some business owner is

they need to.

and there is a real risk of becoming sensitized (exaggerated reaction) to
the compounds after a brief exposure. After you become sensitized even very
minute quantities can set off asthmatic reactions, and there are apparently
a lot of sources of small amounts of isocyanates in everyday products.

I've painted em outside a bunch of times, no mask, no suit, just a slight
breeze. I use a HVLP gun and try not to gulp in big lung fulls of the paint
cloud. Yea, you get a little dizzy if you over do it, just make sure you get
equal time breathing pure air. Jump in, spray it quick and wet, get out of
the cloud and let it dry. Maybe have a cigarette between coats.
Yep, lots of good safety info on this thread, just wanted to say what the
"other side" was doing... can't have too much info when your safety is at

Speaking of which, does anyone know the threshold toxicity level? Usually
something like Mgs per cubic meter. there has to be some point at which isos
are not a health risk or they would be banned. I know people who have painted
Imron outdoors for many years with no ill effect (apparent). from what I've
heard, the iso effects are much more subtle (& insidious) than the headaches &
dizzines described by some here. That may have been caused by the reducers and
other volatiles.

EXPOSURE LEVELS
The OSHA Permissible Exposure Limit, (PEL) for both TDI and MDI is .02
parts per million of air as a ceiling limit. The ceiling is the highest
concentration to which an employee can be exposed. The American
Conference of Governmental Industrial Hygienists (ACGIH) recognizes .005
ppm as their Threshold Limit Value (TLV) as an 8-hour TWA and .02 as a
Short-Term Exposure Limit (STEL) for both TDI and MDI. Most of the data
available on the effects of exposure to isocyanates is for TDI. Because
of this, MDI exposure levels are based on TDI's exposure test data.
The State of Oregon has promulgated a PEL of .5mg/m3 for HDI and a STEL
of 1.0mg/m3. However, these exposure levels have not been adopted yet by
either OSHA or the ACGIH. HDI and all other isocyanates at this time
have no published PELs or TLVs. OSHA recommends using the TDI and MDI
exposure levels as guidelines for other isocyanates.

I'd be concerned about it. All the precautions sure do suck when using
iso paints, no two ways about it. I myself have never thought of using
these paints in an attached garage. I can't get past the explosion and
fire hazard to worry about the health hazard. I can blow the shop to
bits but I still have a home to go cry in.

For those who have built up an intolerance to the stuff ANY exposure
can cause symptoms which can take weeks to go away. My brother was a
pretty good body man and painter - and had to leave the trade in his
thirties because of IsoCyanate intolerance

Richard,
I have a small electric powered compressor that is made
for hook up to a mask for just such work. I have the compressor
only that I paid $900.00 6 yrs ago but used only a few times.
The mask deteriorated and got thrown away,
but they are available. For $200. I would even throw in
free shipping as I have no use for this now.
I could get a pic out if your interested.
Thanks,
Bruce Cramer
