Risk assessment and analysis of biosafety high-pressure steam sterilizers in high-level biosafety laboratories

High-level biosafety laboratory risk assessment is the core component of biosafety laboratory risk management. However, the understanding of risk management, risk assessment and risk response of biosafety key protective equipment in some high-level biosafety laboratories are still at the theoretical level, and risk assessment results lack of connection with a safety management system. This poper utilizes fault tree analysis to evaluate biosafety risks of biosafety high-pressure steam sterilizer, one of the biosafety key protective equipment, to identify risk factors and provide guidance to support risk control management of the equipment.
