An overview of the general safety requirements and safety precautions for using compressed air in machine shops.

General safety requirements for compressed air

The following precautions pertain to the use of compressed air in machine shops:

1. All pipes, hoses, and fittings must have a rating of the maximum pressure of the compressor. Compressed air pipelines should be identified (psi) as to maximum working pressure.
