PPG Concept safety

[John Gausby]

THANKS guys.......I'm off to a contest so there maybe some other responses after this (thanks in advance). I will double check my respirator cartridges with my local PPG store.

Years ago i did the same thing as David. Sprayed with an airbrush without a respirator and was sick for about 36 hours.  Doesn't take much.    You DON'T forget after that!!!!!!!!!!!!!..........................John

John,

The PPG Concept and clear has polyisocyanates, and while I am not an expert, I am certain that it is not beneficial to have these atomic particles absorbed via your lungs.  It is much less of a concern before the material becomes atomized via your spray gun, however there is still concern.  You should do your own research and decide for yourself your risk via dermal and lung exposure to the paint.  For starters, visit http://www.osha-slc.gov/SLTC/isocyanates/index.html.

I can share a personal experience.  I once did a very tiny touch up job with my airbrush, outdoors, and I foolishly did not take the time to find my respirator.  I was exposed for about two minutes to a very small volume of air born PPG concept particles.  I immediately felt tightness in my chest, and that lasted through the night.  I had a hard time sleeping and I felt that I could not get enough oxygen.  The tightness was gone by morning, but I resolved to never expose any part of my body after that and after reading up on the subject.

Whether you are protected sufficiently with a good carbon filter mask is NOT clear (at least to me), and nowadays I am seeing manufacturers recommend a positive pressure, fresh air respirator.  You will also find recommendations on eliminating skin exposure.  That may be a reaction to an over-litigious society, or directed at professionals that are exposed daily, but you have to decide for yourself.

When you read about and hear about becoming sensitized from isocyanate exposure, it is enough to scare you into spending money on safety equipment.  As you can tell, I am pretty paranoid about it.  I am told by paint professionals and have read articles that say the amount of exposure to isocyanates that is required to become sensitized varies per individual, but that everybody has a reservoir.  Once your reservoir is full, the sensitivity sticks with you for life, and causes some serious health problems.  

Best regards,

David Flynt.

Hi folks........I'm ready to spray a 2M fuse using PPG Concept Acrylic Urathane from Radio South. This stuff is new to me after using K&B Superpoxy for many many years.

I've done some reading on safety including several articles submitted by David Flynt in the K-Factor. David recommends that all body skin be completely covered up and i should wear neoprene gloves. Is a full body suit necessary?

My paint booth is a seperate 10 X 10 room attached to my shop with a door. I have a large fan in the window that sucks out any fumes very well . The respirator i use is a new 3M double charcoal. I use an HVLP detail gun and a paasche airbrush for spraying..

Any saftey recommendations from ya'll would be appreciated. I understand this paint can be (especially the chemicals in the hardiner) real nasty..........Thanks.........John Gausby
