Compressed air used with pneumatic tools can be a deadly weapon. Never use compressed air to dry or clean debris from your body. Air at 80 psi can cause a wound or force air bubbles in the blood stream through an open wound. A blast of 40 psi compressed air directed to the head can rupture an ear drum at distance of 4 inches or cause a brain hemorrhage. It can rupture your lungs and intestines if directed at the mouth. So don't point compressed air toward yourself or anyone.
