Compressed air is a form of energy and should be used  with caution.  It should always be remembered that compressed air is dangerous, and can cause grievous injury while actually operating or merely standing close by.

When blowing down, the danger lies in particles of metal and swarf which propelled at high velocity, can get into the operator's eyes and into the eyes of the persons standing nearby, whose reflexes are not conditioned to the danger.

Use of compressed air to blow dust or dirt from body or clothing is a dangerous practice.  As Little as 12 PSI can 'POP' an eye ball from its socket and can also damage the ear drums. Compressed air can enter the blood stream through a cut or a abrasion on the skin.  This has been known to happen with fatal results.  A case history of such an accident is given below.

"A mechanic with a small cut on his finger washed some parts in cleaning fluid.  The holding the parts in his hands, he blew them dry with an air hose.  Shortly thereafter in great pain he staggered to his boss, complaining that his body and head felt as if they were going to explode.

At the hospital, his ailment was diagnosed as air bubbles in blood stream caused by the air jet striking the wound.  He recovered by he could have been a fatality'.

The following precautions will help you to work safely with Compressed air :

1. Use Compressed air only where necessary.

2. use only sound strong hose with secure couplings and never kink hose to stop air flow.

3. Do not use compressed air for blowing out dust, chips, etc.

4. Never direct compressed air towards others or towards your body.

5. Do not clean your clothing or body with compressed air.

6. Never use compressed air for filling cycle/auto tyres without the aid of suitable regulators and pressure guage.

7. Do not handle compressed air when you have a wound or a cut on your hands.

8. Wear hand and eye protection equipment while handling compressed air.

9. Close the air valve immediately after the work is completed.

Carelessness and acting without proper thinking is to be avoided at all times, especially while using compressed air. Remember it is your own attitude that will ultimately either prevent accidents or cause you or others to suffer pain and loss of working time or worse.
