Microbiological safety cabinets are available in 3 different classes, namely Class I, II and III. These classes represent the level of protection that the cabinet has to offer.
Class I provides protection for the person using the cabinet and the environment around it, but not the material inside the cabinet. Class II offers a little more than Class I, as they provide protection for the materials being worked with as well as the operator and their environment. Finally, Class III provides the most protection and is therefore the best choice for those working with materials requiring Biosafety Level 4.
