The Hazards of Overpressure Operation in Autoclave

The Hazards of Overpressure Operation in Autoclave

Overpressure operation in high-pressure steam sterilizers can lead to serious safety hazards and equipment damage.

1. Safety Risks

   - Device Explosion: Overpressure operation may cause the internal pressure of the sterilizer to exceed its designed capacity, potentially triggering an explosion. Such explosions can not only damage the equipment but also cause severe injuries to operators and the surrounding environment.

   - Container Rupture: Continuous overpressure operation can subject the sterilizer's container walls to excessive stress, leading to material fatigue and eventual container rupture.

2. Equipment Damage

   - Safety Valve Failure: Overpressure operation may cause frequent activation or even failure of the safety valve. Once the safety valve fails, the sterilizer loses a crucial safety mechanism, further increasing the risk of explosion.

   - Control System Malfunction: Overpressure operation can damage the sterilizer's control system, causing deviations in temperature and pressure sensors, which prevents the device from properly monitoring and regulating internal pressure and temperature.

3. Impact on Sterilization Effectiveness

   - Incomplete Sterilization: Overpressure operation may result in uneven steam flow within the sterilizer, affecting sterilization effectiveness and leaving some areas inadequately sterilized.

   - Item Damage: Excessive pressure and temperature can damage sterilized items, particularly sensitive medical instruments and biological products.

4. Legal and Economic Consequences

   - Legal Liability: Accidents caused by overpressure operation may result in legal liabilities for operators and related institutions, including compensation and lawsuits.

   - Economic Losses: Equipment damage and accident handling can lead to significant economic losses, including repair or replacement costs, downtime losses, and expenses related to accident investigation and management.

To avoid the aforementioned hazards, it is essential to strictly adhere to the operating procedures of high-pressure steam sterilizers, conduct regular equipment maintenance and safety inspections, and ensure the device operates within normal pressure ranges. Additionally, operators should receive professional training to handle emergency situations effectively.
