Aerosol Generation. If any liquid is spilled on a rotor, it will be dispersed as a particulate mist when the centrifuge is run. Part of this mist will be fine enough to form a relatively stable aerosol which will tend to be dispersed throughout the laboratory. Such spills should be thoroughly cleaned up before running the centrifuge.

Centrifuge Operations When microorganisms are not adequately contained within a centrifuge, aerosols can escape during the high-speed spin process. This may occur when spinning uncapped samples, or when a leak, spill, or breakage of the tube occurs. Minimize the risk of aerosol production when centrifuging by observing the following precautions:
