Damn, man! Good thing your Significant Other is a Doc! You seem to have a really bad effect on the workers around you!! 

If you work in construction long enough, you will see that type of thing. For the most part, There are very few accidents, but there alot of idiots hurting themselfs. The guy that filled his butt cheek up with paint is a perfect example. He took the trigger guard off the airless. Thru the gun and hose over his shoulder to come down the ladder. The formen stoped by half way down, he turned around and leaned back on the ladder. he did 4 things wrong.
1 took the safety guard off of the airless
2 thru the gun over his shoulder
3 stoped half way down a ladder
4 turned around backwards on a ladder.
If he had not done any one of those things, he would have been fine.
you don't want to mess with a airless, not only will they cut you deep, they will also inject paint. 2500-3500 psi thru a tip that is .015" pumping .5-2.5 gallons a min is no joke. the more industrial versions are even worse.
