Safety is the basis for people to pursue all the goals of a better life and the cornerstone of personal development and social development. With the development of the times, people are increasingly aware that safety knowledge is an important part of the knowledge structure of high-quality talents in the new century. After the enrollment expansion of colleges and universities from 65438 to 0999, the number of students and the ratio of students to teachers increased greatly. Teachers don't have much energy to manage students. In addition, based on the requirements of society and the country for students' innovative ability and practical ability, the number and scale of laboratories have increased, students' experiments and scientific inquiry activities have increased, and more and more schools have opened laboratories to facilitate students to complete experiments independently. In this case, how to ensure the safety of the experiment? In China's educational laws and regulations, although more and more attention is paid to laboratory safety and environmental protection, there is no strict requirement for students' experimental safety. Therefore, some schools have not included experimental safety in the teaching plan, which leads to students' lack of necessary experimental safety knowledge in experiments. Improper use of toxic and harmful reagents, not paying attention to protection; Conduct wrong and dangerous experimental operations; Dumping experimental wastes at will; There is a lack of scientific rescue and safe escape skills in experimental accidents. Chen Yan and others selected 180 students from six universities to conduct experimental research and teaching of chemistry and biology in Guangzhou University Town, and investigated the situation of laboratory safety education. The results show that only 6 students, accounting for only 3.5%, think that they can clearly handle the abnormal situation of sudden safety accidents in their laboratory, which shows the lack of experimental safety knowledge. Therefore, it is very necessary to carry out basic and systematic laboratory safety education and training for students.

Second, thinking about the curriculum.
