[AT] respirators and Isocyanates (Urethane paint)

[Cecil Bearden]

If you need a filter for breathing air, a whole house activated carbon 
filter works well.  I used one for a long time before I bought my air 
compressor filter I now use for sandblasting.  I painted some black 
aliphatic paint with an airless sprayer and used a carbon filter mask 
that did not fit good.  I did not know about the fumes leaking in 
because I sleep with a CPAP unit and my nose is burned out as far as 
smelling anything.  I can stand over a roadkill skunk and not smell 
anything!!   Anyway, I ended up coughing up black paint for 3 days and 
getting chemical pneumonitis.  I now have to be very careful when I 
begin to have any congestion as I burned my lungs and cannot afford any 
congestion.   A supplied air mask is the best way to prevent breathing 
the bad stuff....
I am going to use my sandblast hood with the tear offs for painting...   
Maybe I can keep the sight clean.  I always had problems with paint mist 
in my eyes.
