As a clinical laboratory, the clinical laboratory has a strong risk of biological transmission, and the bacterial culture samples of the microbial group and the COVID-19 nucleic acid detection samples of the PCR group require the operators to do personal protection, strictly autoclave the medical wastes, and do a good job in handing over the medical wastes to prevent the spread risk of pathogenic microorganisms.

Zhang, deputy chief technician of the laboratory, made a detailed interpretation of the Biosafety Law of People's Republic of China (PRC) and other relevant laws and regulations, requiring general practitioners to strictly abide by the Biosafety Law and do a good job in laboratory biosafety.

Combined with the actual work of the clinical laboratory, the classification and treatment methods of medical waste are described in detail. The medical wastes in the laboratory are mainly infectious wastes, damaging wastes and chemical wastes, and all kinds of waste treatment methods have strict standards.

At present, the epidemic situation in COVID-19 has not been effectively controlled, and the detection task in COVID-19 is heavy. It is necessary to strictly implement COVID-19's inspection operation specifications, and do a good job in personal protection, sterilization, discharge and handover of COVID-19's inspection samples to ensure the biological safety of the laboratory.

Taking this training as an opportunity, the laboratory conducted a comprehensive inspection of the biosafety protection facilities of various professional groups in the laboratory, and randomly checked the biosafety knowledge of the staff, focusing on the disposal methods of infectious sample overflow.

The PCR group, microbiology group and other key professional groups were inspected in detail, focusing on the disinfection measures for specimen reception, the operating specifications for COVID-19 detection and the disposal methods for COVID-19 specimens after inspection.

As an important medical department in the hospital, the laboratory is an important link of clinical examination, and the specimens of all clinical departments are gathered here, which is the key link of hospital biological safety. This training not only improved the staff's awareness of biosafety, but also further strengthened the biosafety defense line through the inspection of various professional groups.
