Calculation and analysis of aerosol transmission risk between biosafety laboratories

Combined with a three-level biosafety laboratory project, this paper uses the dynamic isolation theory for calculation and analysis. The results show that it is necessary to set up a buffer room for the core of the biosafety laboratory. Increasing the air change rate of the room has little impact on the isolation coefficient. The longer the emergency disposal time of personnel, the greater the system isolation coefficient, which can effectively reduce the biosafety risk of aerosol transmission.
