The use and limitations of the safety cabinet should be explained to each operator and operated strictly according to the requirements, such as the use of "self-cleaning" when the cabinet is turned on in advance, reasonable placement of the items in the cabinet, and regular maintenance and verification. The biological safety cabinet cannot protect the operator when there is an error in operation or leakage or breakage occurs. The air curtain in front of the biological safety cabinet is very fragile and can be easily disturbed and polluted. During the experiment, the position of the front window could not be opened at will, the operation movement was gentle, and the arm should avoid frequent entry and exit of the safety cabinet to prevent disturbing the airflow. When working in the safety cabinet, opening and closing the door, people walking in the room, and even coughing behind the operator's back will form turbulent flow and increase the amount of microbial aerosol overflow, resulting in laboratory contamination.

Therefore, operators must firmly establish safety awareness, develop good operating habits, prevent illegal operations, strictly follow the microbiology standard operating procedures and biosafety laboratory operating procedures, and use standardized experimental equipment. Personal protection is the last protection against laboratory aerosol infection. It usually consists of physical protection and vaccine immunization. Physical protection is mainly for respiratory and eye protection, such as goggles, masks, protective masks, positive pressure helmets and positive pressure. work clothes etc. After the biological safety cabinet is put into use, its management is an important task and a weak link. Due to the unclear responsibilities of equipment personnel and experimental personnel, and neglect of management, it will bring great hidden dangers to laboratory safety. It must be established The scientific management system is strictly implemented, the responsibility is implemented to the people, and supervision is carried out to ensure the safety of the laboratory.
