Death operation: make coffee with a beaker in the laboratory, she went to the ICU after drinking it

Experiment safety is the most important thing. Only with a healthy body and a strong body can there be stars and seas. Every experimenter should keep the laboratory management regulations in mind, and never regard it as a child’s play. It must be for oneself and others. Responsible for the safety of your life!

For the pot friends who stay in the laboratory all day, drinking a cup of coffee when physically and mentally exhausted is delicious and refreshing. However, when the laboratory collided with coffee, what appeared was not a beautiful spark, but a safety accident, ranging from vomiting and diarrhea to death by poisoning.

Netizens broke the news that someone once used a beaker filled with barium chloride to brew coffee. After drinking this cup of coffee with special ingredients, the person fell into a coma with nausea and vomiting, respiratory failure. He was sent to the intensive care unit of the hospital for a long time, but he could not recover.

That washed-out beaker with barium chloride in it killed an invisible man, instantly killing a young man. An unremarkable beaker in the laboratory, you can never imagine what it will be used for. One minute it’s beautiful in a corner of the lab, the next it’s being discovered by food stars to make delicious food. Some students use beakers to cook instant noodles in the lab. They open the alcohol stove at night and use local materials. Instant noodles and beakers are perfect partners.

The experimenter is in the lab eating and eating, unaware of the dangers that lurk beneath. Chemicals that linger in the air, in laboratory equipment and on workbenches are accumulating in the body through food in an invisible form, eroding the body’s health.

Eating in a lab can be dangerous. Back in 1949, the Journal of the American Academy of Medical Sciences reported on a tragic case of eating a hamburger in a lab. On November 25, 1948, H. W., a young chemist, made some synthetic reactions using phosphorus pentachloride, hydrochloric acid, acetyl chloride, and diazomethane. Soon he repeated the experiment with a much larger dose of the reaction. In order to save time and finish the work at hand, he ate a hamburger for lunch in the lab. Soon, the 28-year-old chemist developed symptoms similar to a cold and an upper respiratory infection that failed to be relieved by antibiotic treatment, and he died a few days later.

The man had no idea that the burger had accelerated his death, and despite conducting his experiments in the fume hood, he had inadvertently inhaled the chemical gas. Diazomethane is fat-soluble and highly toxic, and the greasy burger he ate dissolved a large amount of diazomethane gas, which became an invisible hotbed of poison.

This is a hard lesson to learn. The danger of eating in a laboratory is invisible, invisible, a knife that kills without blood. When you cook instant noodles in a beaker, you don’t know the residual chemical reagent is moving up and down in the beaker. When you cook them in a beaker, you don’t know that toxic substances in the laboratory air are reacting with them everywhere; When rice is cooked in a steam pot, it is not known that the chemical toxin in the steam pot for years has already infiltrated into every grain of rice along with the steam. Some people look at the microscope while eating, infatuated next to the reagent to drink into, even gastric lavage also fell disabled; Some people’s experimental and living areas are mixed together, and their potted plants never survive more than six months. Synthetic inferior ester and apple fragrance similar, someone curiously licked, the tongue mucosa swelling for half a month; Someone used a laboratory blower to bake bread, and within six months, he died of stomach cancer. The list is so long that the dangers of laboratory dining, seemingly innocuous enough to cause real harm in the short term, are as ill as a frog boiled in warm water when it is discovered. It’s safe to not eat in the lab, even though some of humanity’s greatest food inventions have been made in the lab.

In 1879, John F. After a long day in the lab studying coal derivatives, Constantine of Hopkins hurried home to eat without washing his hands, his hands smeated with chemicals that made everything sweet, and he discovered saccharin, which changed the history of modern food. But that was just luck in the extreme. If Constantine had been on diazomethane, it would have been another sad story.

When doing experiments, the hands will inevitably come into contact with toxic reagents, which are carelessly sent into the body through food, drink and fruit. Over a long period of time, it will surely cause great harm to the human body. At the same time, the use of clean utensils in the laboratory to cook food, surrounding volatile reagents will also enter the food, its harm is self-evident.

So, how should we maintain our own health when we are in the laboratory and exposed to a lot of biochemical reagents?

1. Be sure to wear lab coats and gloves for the experiment, and wash your hands promptly after the experiment. The remaining chemical reagents on your hands are beyond your imagination.

2. Separate the living area from the experimental area as much as possible, and don’t stack daily necessities in the experimental area. Many little fairies have the habit of hoarding snacks, and refraining from eating or drinking water during the experiment is the primary health criterion. If you are too tired to do the experiment, you can add energy before doing the experiment.

3. For toxic, volatile, and corrosive experiments, it must be carried out in a fume hood, take precautionary measures, and do not take a fluke.

4. The laboratory should be cleaned and ventilated frequently. Fairies and fairies should exercise more, breathe more fresh air, speed up the metabolism in the body, regularly discharge toxins in the body, and take precautions! Laboratory safety is the most important thing. Only with a healthy body and a strong body can there be stars and seas. Every experimenter should keep the laboratory management regulations in mind. You should never regard it as a child’s play, but do it for yourself. Responsible for the safety of others’ lives!
