Risk assessment of facilities and equipment in high level biosafety laboratories based on fault tree analysis

Briefly presents the definition and main points of risk assessment of biosafety laboratories, presents the definition and characteristics of fault tree analysis method, and preliminarily establishes a fault tree model for the facilities and equipment of high level biosafety laboratories. Presents some basic risk factors that can lead to pathogenic microorganism release, with the risk identification of facilities and equipment of the high level biosafety laboratories. It provides a basis for risk assessment and control of the high level biosafety laboratories.
