Its goal is to prevent these microorganisms from leaking or accidentally releasing into the environment and ensure the safety of workers and the public. Biosafety laboratories are usually divided into four grades, which are used for the research and treatment of microorganisms with different degrees of danger. These laboratories have strict protective measures and operating procedures to ensure the safety of people and the environment in the laboratory.
Expanding knowledge: laboratory biosafety
Refers to the protective measures (hardware) and management measures (software) taken to avoid laboratory biological hazards caused by various harmful biological factors. The definition of biosafety in the national standard "General Requirements for Laboratory Biosafety" is a comprehensive measure to avoid the exposure of hazardous biological factors to laboratory personnel, their diffusion outside the laboratory and their harm.
Laboratory biosafety level:
Laboratory Biosafety Laboratory is divided into four grades: P 1, P2, P3 and P4 according to the harm degree and protection requirements of the microorganisms it handles. P 1 Laboratory mainly deals with low pathogenic microorganisms, P2 with medium pathogenic microorganisms, P3 with high pathogenic microorganisms and P4 with extremely pathogenic microorganisms.
Laboratory biosafety equipment:
Biosafety laboratories need to be equipped with various biosafety equipment, such as biosafety cabinets, autoclaves, sterilizers, laboratory protective clothing, gloves, etc. To ensure the safety during the experiment.
Laboratory biological safety operation procedures:
Laboratory biological safety operation procedures include laboratory access system, laboratory personal protection, laboratory disinfection and sterilization, laboratory waste disposal, laboratory emergency plan, etc. , aiming at standardizing laboratory biosafety operation and reducing laboratory biosafety risks.
Laboratory biosafety training:
Laboratory biosafety training is an important means to improve laboratory staff's biosafety awareness, knowledge and skills. The training content should include the basic knowledge of laboratory biosafety, the operating rules of laboratory biosafety, the use and maintenance of laboratory biosafety equipment, and the emergency plan of laboratory biosafety.
Laboratory biosafety management;
Laboratory biosafety management refers to ensuring the implementation of laboratory biosafety policies, objectives and plans by establishing a biosafety management system. Biosafety management system should include organizational structure, personnel responsibilities, biosafety training, laboratory biosafety operation procedures, laboratory biosafety equipment management, laboratory biosafety inspection and evaluation, etc.
