Open Baidu and enter the words “lab” and “explosion”. You will find that there are endless explosions in the lab from home and abroad. The pain in the labs is still vivid, “death” and “serious injuries”. Words such as shocking people.
Maybe many people think that the safety protection work in the laboratory is not necessary, and it has not always been attached much importance to in the laboratory, even some small laboratories, even the most basic fire-fighting equipment, emergency shower equipment, safety problems can be imagined know. Many people who have just entered the lab are more concerned about it. However, after a long time, they often think that it does not matter. The white coat does not wear it, and even gloves do not wear it.
In the long run, the awareness of the safety of the laboratory is lax. Once a variety of safety accidents are encountered, the consequences will be disastrous. Even due to inappropriate handling methods, minor accidents may also cause disasters.
For the friends working in the lab, we can now examine the lab where we are, and are the protective glasses, gloves and masks ready? When it is midsummer, whether or not people wear short skirts and go into the lab on high heels Is the white labyrinth left on the side, has the refrigerator in the laboratory been diverted for other uses, and is there special protection for special reagents?

It is estimated that he needs to be hospitalized for skin graft surgery.
In addition, there are many netizens who have recorded the lessons learned in the lab in the forum so that they can take warning:
Once I used a separatory funnel. There was a small crack on the funnel. I didn't care. Later, during the shaking, the bottle suddenly exploded, splashing me with a lye;
One of my classmates accidentally fell to the floor with an alcohol light and caused a nearby sofa to catch fire. In a hurry, he used his sandals to get out of the fire. As a result, the fire was not burned when he stepped on his feet.
Once I was doing experiments, I put a bottle of concentrated ammonia bottle cap tightly and after use, I wanted to use the bottle cap to pick up the bottle and put it in the medicine cabinet. As a result, the bottle fell to the ground and broke. Full house is full of ammonia smell.
