The most important thing, especially if you are using urethane paint with hardner is have the proper filters in your resporator. Remember your lungs don't have a drain valve, what goes in there stays in there. If paint hardens in your lungs it can kill you.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
