Where a rotary screw air compressor hurts people
- The receiver tank holds full pressure after the compressor stops. Close the discharge valve and drain it to 0 psi.
- Auto-restart: a compressor on standby starts by itself when pressure drops. Never trust a stopped compressor.
- Oil and discharge piping stay hot after shutdown.
