It makes for some good "Work Boogers", ( T M )................. Wear a mask!!!! What's a "10 hour osha" and a "30 hour osha"? If you have had ANY Osha training, you should know SOMETHING about P P E, (personal protective equipment)
It can give you a bad case of hotrodatosis. Theres no cure for it. Actually its habit forming. You end up looking for more and more rust to breath. (hack hack) You will find your self looking in back yards and behind bushes while you drive trying to find rust too feed your habit. It can almost be as dangerious as driving and drinking. You may swerve from time to time and even do U turns in the middle of the road. It helps to have a designated driver at times like these. Just hang in there and try not to injest too much or it could turn into ratroditis.
