1, teachers are the first line of defense to prevent students from injury accidents. Teachers should not only have a high sense of safety, but also have the responsibility and obligation to educate students to establish the idea of "safety first". 2. Teachers should achieve "five hearts", that is, caring for students, carefully managing students, patiently educating students, influencing students with love, and understanding students with tolerance. 3. Teachers should strive to improve their safety awareness and ability to deal with injuries. 4. Teachers should also consciously reduce their psychological pressure. 5. Teachers should strengthen students' mental health education. Teachers' ideological level determines their safety level. In the final analysis, the occurrence of students' major safety accidents is caused by teachers' ignorance of students' ideological understanding and careless safety education and safety precautions. As long as teachers don't have any luck in their work, they can avoid injury accidents as much as possible by operating according to standard procedures and implementing safety work in a down-to-earth manner.
