Since the implementation of the State administration for market supervision and administration's Measures for the Administration of the Qualification of Inspection and Testing Institutions (Order No. 163) amendment and Measures for the Supervision and Administration of Inspection and Testing Institutions (Order No. 39) in 2021, regulatory authorities at all levels have significantly intensified their efforts in conducting random inspections and targeted rectification campaigns. Cases of inspection and testing agencies being stripped of their qualifications, suspended, fined, or publicly reprimanded have frequently appeared in the media, attracting significant attention from the industry. As inspection and testing agencies, it is imperative to enhance their quality compliance management capabilities, thoroughly study and understand various regulatory policies and cases, and strengthen internal quality compliance management to mitigate the risk of administrative penalties, thereby boosting the confidence of all sectors of society in the industry. This article first introduces the necessity and urgency of introducing a quality risk management mechanism in laboratories. It then describes various sources of risk. Finally, it elaborates on the planning, implementation, performance evaluation, and improvement of the quality compliance risk management mechanism in laboratories, aiming to help readers initially grasp and understand the basic approach to implementing quality compliance risk management in laboratories.

In university laboratories, physics thinking dominated by science and technology is in a dominant position. Usually, university laboratory managers summarize the causes of accidents and carry out safety education or inspection according to the conclusions. This kind of summary management method is essentially based on physical thinking, and its main disadvantage is that it can not cover all the hidden dangers, and accidents will continue to happen. Biological thinking comes from biological system, and its characteristics of co-existence with risk are highly compatible with laboratory safety management. By applying biological thinking to laboratory safety management, this paper gives full play to the advantages of biological thinking to solve laboratory safety problems, and carries out safety education by using biological thinking, in order to enhance the safety awareness of teachers and students, expand the scope of hidden danger prevention, and provide unified thinking methods for some specific operations in current management.
