[AT] respirators and Isocyanates (Urethane paint)

[John Wilkens]

Cecil, what is a "whole house" carbon filter anyway?....and what is 
the "air compressor filter" you bought??  Trying to get a visual 
picture.  Sure sorry to hear about your lung trouble.  I sure want to 
avoid that!   I think I agree that the air supplied mask is the 
safest way to go.  So why do you just use the sand blast hood?  Or do 
you use a mask under it?   Do you get enough air flowing through the 
hood to eliminate any paint fumes from getting in?   I've got to 
think about all the other guys' suggestions too.   Thanks everyone!       John
