To outline safe procedures in the use of compressed air.


All University personnel using compressed air.


The practice of using compressed air to remove dust from clothing is extremely dangerous and entrained particles may puncture the skin or enter the eyes. Using compressed air to clean machinery or equipment can also be hazardous and should only be done under controlled conditions.


  1. Compressed air shall not be used to clean clothing.
  2. Where compressed air must be used to clean machinery, equipment or any surface, e.g., automobile carburetors, the following precautions must be taken:
    • Eye protection, protective clothing and equipment shall be worn by any person using compressed air for cleaning machinery, equipment or any surface.
  3. Any area where compressed air is used for cleaning machinery or equipment must be maintained clear of persons who are not directly involved with the work at hand.
  4. A blowpipe, complete with control valve, shall be installed on the end of the hose.
  5. The compressed air supply shall be limited to 69 kPa or safety nozzles shall be used to have the same pressure limiting effect.
