Laboratory biosafety mainly involves the safety of pathogenic microorganisms, laboratory animals, and genetically modified organisms. Experimental samples must be stored centrally, destroyed regularly, and discarded at will is strictly prohibited. The laboratory animals shall be managed by special persons, and the corpses, organs and tissues of laboratory animals shall be handled scientifically. Bacteria, viruses, vaccines and other items should be managed by special personnel, and a registration system for approval, collection, storage and distribution should be established and improved. The remaining experimental materials must be properly kept, stored, disposed, and recorded in detail; the waste containing pathogens must be strictly disinfected, sterilized and other harmless treatment, and sent to a qualified professional unit for destruction. It is strictly forbidden to litter, throw or dump at will.

There are many types of biological laboratories, and many kinds of cryo freezer boxes experiments can be designed according to different experimental purposes, and the corresponding safety precautions and focuses are also different. Some general considerations are listed below.

(1) Experiment instructors are the instructors and guardians of students conducting various biological experiments. Before each experimental class, the instructor must conduct a preliminary experiment to confirm the success rate and safety of the experiment and ensure that the students' personal and health are not harmed.

(2) In each experimental class, the instructor must emphasize safety precautions and operating procedures. If the precautions and operating procedures are not emphasized, the accident teacher shall bear the main responsibility; if the students violate the safety precautions and operating procedures, the accident students shall bear the main responsibility.

(3) If you need to use sharp-edged instruments such as knives and scissors during the experiment, the instructor must instruct the students to use the instruments correctly, and warn the students not to fight each other or act rudely, in order to avoid being punctured or scratched by the sharp blade. In the event of an accident, go to the infirmary for bandaging, or take the student to the hospital for treatment.
