COMPRESSED AIR

  1. Never use compressed air or other compressed gases in excess of 10 pounds per square inch gauge to blow dirt, chips, or dust from clothing while it is being worn.
  2. Never use compressed air or gases to empty containers of liquids where the pressure can exceed the container's safe working pressure.
  3. Use personal protective equipment such as safety glasses to protect employees from eye or body injury.
  4. Make sure abrasive blast cleaning nozzles are equipped with an operating valve which must be held open manually, and that a support is provided on which the nozzle may be mounted when not in use.
  5. Do not use compressed gases to elevate or otherwise transfer any hazardous substance from one container to another unless the containers are designed to withstand (with a factor of safety of at least four) the maximum possible pressure that may be applied.
