Seal periodic inspection process verification and risk control：Inspect seal compatibility and condition and retest pump-down and hold curves after replacement. List over-temperature, gas loss, abnormal pressure, open-door and power-loss faults, and define the controlled equipment state for each.

Key points for selecting equipment for periodic inspection of seals：Inspect seal compatibility and condition and retest pump-down and hold curves after replacement. List over-temperature, gas loss, abnormal pressure, open-door and power-loss faults, and define the controlled equipment state for each.

Sensor calibration plan process verification and risk control：For sensor calibration, identify position, range and calibration results and compare curves after replacement. Distinguish process control from independent protection; check sensors, setting permissions, reset conditions and alarm records with a supplier demonstration.

Distinguish process control from independent protection; check sensors, setting permissions, reset conditions and alarm records with a supplier demonstration.

Abnormal shutdown review process verification and risk control：For abnormal shutdown, correlate alarms, utilities and sample state on a timeline and check results after recovery. Check relief and exhaust paths, door-opening conditions and maintenance isolation; solvent-bearing or combustible loads require a separate configuration assessment.

Implant Cleaning and Drying Process Verification and Risk Control：For implants, examine surface particles and residual moisture without treating drying results as sterilisation results. Check filter temperature compatibility, installation seals, circulation paths and service access; placement in a cleanroom does not establish internal oven cleanliness.

Low-particle drying process verification and risk control for consumable packaging：For consumable packaging, inspect shrinkage, seal integrity and internal particles with the actual packaged load. Test particle deposition and temperature distribution with actual trays and packaging; record recovery after loading, unloading and filter replacement.
