What actions can reduce aerosol generation?

1. In order to prevent the hot inoculation loops from being placed in the bacterial solution to generate aerosols, two inoculation loops can be used alternately.

2. When mixing the microbial suspension, use rotary rotation instead of left and right shaking, which can reduce the generation of aerosol; do not wet the test tube plug with the suspension when shaking, it is best to wrap a layer of sterile paper towel outside the test tube plug to prevent aerosols escape.

3. Centrifugation of liquids containing pathogenic microorganisms: Relatively few laboratory-related infections are caused by centrifugation, but one accident that often exposes many people to infectious pathogenic microorganisms is the unnoticed release of aerosols during centrifugation, due to After centrifugation, a large amount of aerosol was formed in the centrifuge tube. Therefore, the centrifugation of the sample must be carried out in an open laboratory, and the vacuum blood collection tube must be opened in a biological safety cabinet or placed in a centrifuge for 30 minutes before opening.
