Danger! Do not use an air compressor to clean objects, machines, workbenches, clothes, etc. It must be remembered that using compressed air to clean objects, machines, workbenches, clothing and other things is a dangerous move. Strong airflow or small particles in the compressed air can cause personal injury.

The compressed air pressure used by compressed air tools in the workplace is about 0.6 to 0.8 MPa, which is equivalent to 3 to 4 times the pressure of a fully filled car tire. Therefore, although compressed air is a very useful energy source, if it is not used correctly or used for the wrong purpose, it can easily cause serious injuries and disasters.

　　(1) Relying on pressure, compressed air can wash away small particles of dust, but these dust can rush into the eyes or scratch the skin. The degree of possible damage depends on the size, weight, shape, composition and speed of these blown particles.

　　(2) Compressed air itself is a serious harmful source. In extreme cases, compressed air can enter the bloodstream through skin wounds or open tissues of the body. In medicine, air bubbles in the blood flow are like thrombus, forming a dangerous blood flow block. Blood clots in arteries can cause coma, paralysis or death due to their size, duration, and location.

　　 Under a pressure of 40 psi (approximately 2.7 standard air pressure), the eardrum can be blown out from the ear 4 inches (approximately 10 cm) or cause brain damage. Under a pressure of as little as 12 psi (about 0.82 standard air pressure), the eyeball can be blown out of the eye socket. Compressed air can even blow into the belly button through clothes, causing the intestines to burst. Blow straight into the mouth, compressed air can blow the lungs.
