Misunderstanding 2: Getting ahead

Improper selection of biological safety cabinets. According to the structural design, ventilation ratio, and protection objects and degrees, biological safety cabinets are divided into Class I, Class II and Class III, of which Class II is further divided into A2 and B2 types. Different levels of biosafety laboratories should use different levels of biosafety cabinets, and appropriate safety cabinets can also be selected according to different types of protection and protection. When operating a small amount of volatile chemical reagents or radionuclides, you can choose a Class II B2 biological safety cabinet; when operating a large amount of volatile chemical reagents or radionuclides, you must use a Class II B2 biological safety cabinet. At present, the most widely used in the world is the Class II A2 type safety cabinet, which can meet the general purpose of the hospital, and is more economical from the perspective of energy saving. In actual work, many units believe that equipment selection should have a certain advance, and often choose B2 type when A2 type can meet the application, causing many problems. The selection of safety cabinets should be mainly considered from the performance of safety cabinets, such as high-efficiency filters, air duct design, alarm devices, negative pressure protection and other indicators to compare the advantages of safety cabinets.
