We must understand what are the operations that generate aerosols?

1. Mild (<10 particles): glass slide agglutination test; pouring venom; burning the inoculation loop on a flame; extracting the culture medium.
2. Moderate (11 to 100 particles): inject, pour, and suspend bacterial solution before and after centrifugation; bacterial droplets fall on different surfaces; extract bacterial solution from ampoules with a syringe; inoculate a plate, test tube or triangle flasks with an inoculation loop , etc.; opening screw caps of culture vessels; breaking dishes with culture.
3. Severe (>100 particles): the centrifuge tube is broken during centrifugation; the ampoule of dried bacteria is broken; the ampoule of dried bacteria is opened; the lid of the blender is opened immediately after stirring; the needle tip of the syringe falls off and the bacteria liquid is sprayed.
