Recently, I was asked to engage in a topic of falling objects on campus. I asked: 1. How to calculate? Is there a real case? 2. How can schools prevent it?

1. As the name implies, if someone throws something from upstairs or high places or something falls for other reasons, it will only hurt people. There are many types of real cases, just Baidu;

2. Prevention depends on what type, mainly on education, and the objective factors, such as loose objects and falling, should be aware of foresight, and the old attached facilities should be inspected in time, and the high windowsill and glass should meet the national building safety standards;

3. Follow legal procedures.
