There are safety mechanisms for pneumatic systems, pressure relief valves are one way to prevent over-pressurizing the system.

You’d want to have a system like this installed by a licensed pipefitter and properly commissioned and tested before operating it, along with regular maintenance.

What kind of maintenance?

Periodic tests of joints and valves to ensure they aren't leaking or stuck, respectively. Servicing the air/water separator so that the stored air is dry rather than moisture laden, causing condensation and rusting inside the piping and storage tanks (see: stuck valves). Changing the compressor oil. Making sure no one stuck a metal blank on the emergency relief, making it useless. Hydrostatic load tests of the storage tanks. Things like that.
