A laboratory at Nanjing University of Aeronautics and Astronautics in Jiangsu Province exploded. How can we avoid such an accident from happening again?

When I saw this news, I felt very sad in my heart, because the people who conduct experiments in this school are all top students. But regardless of whether you are a top student or not, if such a regrettable thing happens during an experiment, we will treat it as a tragedy.

After this incident, we should evaluate the safety of the laboratory to a certain extent. The equipment in the laboratory can be used and managed only when the safety of the laboratory is ensured. If the experimental equipment is used without being sure whether the equipment in the laboratory is relatively safe, then it is very likely that there will be too many safety hazards that will cause students to All kinds of surprises happen. Such an accident would most likely result in death or injury to the students. Therefore, it is particularly important to emphasize laboratory safety at this time.

When we do experiments, we must pay attention to the safety of experimental equipment and the safety of drugs. When we were studying chemistry in middle and high school, we knew that we should pay attention to the dosage and use method of each chemical reagent when mixing chemical reagents and conducting experiments in the laboratory. Because many kinds of chemical reagents will cause explosions after collision, so at this time, if we do not control the dosage of each drug well, an explosion may occur. Once an explosion occurs, it is likely to cause serious losses to the lives of students doing experiments. Therefore, teachers who are familiar with the laboratory environment should be allowed to lead students who are unfamiliar with the laboratory to perform step-by-step operations. Only after students are completely familiar with the layout of the laboratory and the techniques used in conducting chemical experiments can students feel confident Go to the laboratory independently to perform experimental operations.

The accident has now been effectively contained. Now the students at the school have gradually stabilized, and relevant departments have also launched an investigation into the cause of the explosion. For the students who were killed or injured during the experiment, relevant agencies also dealt with and comforted them accordingly.
