Don’t do it!
Osha recommends to never use compressed air for personal cleaning, but they don’t really say why. The second link gives a handful of reason why not to do it:
- Compressed air accidentally blown into the mouth can rupture the lungs, stomach or intestines.
- Compressed air can enter the navel, even through a layer of clothing, and inflate and rupture the intestines.
- Compressed air can enter the bloodstream, and death is possible if it makes its way to blood vessels in the brain. Upon reaching the brain, pockets of air may lead to a stroke.
- Direct contact with compressed air can lead to serious medical conditions and even death. Even safety nozzles which regulate compressed air pressure below 30 psi should not be used to clean the human body. If an air pocket reaches the heart, it causes symptoms similar to a heart attack.
- As little as 12 pounds of compressed air pressure can blow an eye out of its socket.
