An animal biosafety level-3 laboratory(ABSL-3)is a high-level biosafety installation that can conduct experiments on animals infected with highly pathogenic microorganisms.In recent years,with the continuous characterization of emerging and re-emerging infectious diseases,high-level biosafety laboratories have played increasingly important roles in pathogenic mechanism and drug and vaccine research and development.The demand for ABSL-3 is increasing year by year.At the same time,there is also a growing demand for personnel who are competent in working in ABSL-3.The systematization,normalization,and standardization of pre-service training have become important to guarantee a reduction in the risks to personnel working in ABSL-3.Training of ABSL-3 staff needs to be carried out in specific simulated laboratories.Therefore,it is necessary to construct simulated ABSL-3 and establish scientific and effective operating standards and mechanisms.This paper comprehensively introduces the design,construction,operation,and functions of a simulated ABSL-3 installation.
