1. Do not use compressed air for cleaning dust, dirt, chips, liquids or anything else from your clothing or skin.
2. Always wear appropriate PPE (safety eyewear, hearing protection, etc.).
3. Never use compressed air or gases to empty containers of liquids where the pressure can exceed the container's safe working pressure.
4. Ensure that 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.
6. Air compressor tanks subject to an internal or external pressure greater than 15 psi require a Cal/OSHA operating permit. Air tanks having a volume of 1.5 cubic feet or less which have safety valves set to open at not more than 150 psi do not require permits to operate.
7. All air compressor tanks must be protected by at least 1 safety valve that will ensure safe operation of the tank. Tanks in excess of 2,000 gallons must be fitted with at least 2 safety valves.
