Current Situation and Challenges of Safety Management of Chemical Laboratories in Universities: Problems and Countermeasures

University chemistry laboratory is an important base for teaching experiment and scientific research, and its experimental activities and scientific research results play an irreplaceable role in cultivating students' practical ability and promoting the development of the subject. However, with the increase of the frequency of laboratory use and the improvement of experimental complexity, the safety management of chemical laboratories in colleges and universities has become increasingly prominent. Laboratory accidents can not only cause serious harm to people and the environment, but can also have a negative impact on a school's reputation and the quality of education. Through the field investigation and data analysis of chemical laboratories in many colleges and universities, it is found that although many colleges and universities have established a set of safety management system, there are still many deficiencies in practical operation, such as weak safety awareness, imperfect safety facilities, insufficient safety training and lack of emergency plans. These problems not only threaten the safe operation of the laboratory, but also restrict the smooth development of scientific research and teaching activities. In view of the challenges facing the safety management of chemical laboratories in colleges and universities, safety education and training should be strengthened to improve the awareness and attention of teachers and students to laboratory safety. Secondly, it is necessary to improve the safety facilities and ensure that the hardware equipment of the laboratory can meet the safety requirements. In addition, a sound safety management system and emergency plans should be established to respond quickly and effectively in emergency situations.
