A university doctoral student Sun students in doing experiments, glass bottles suddenly exploded, broken glass floating around, scratching its human body in several places, around the students to help him bundle light press, and sent to the Shenzhen University General Hospital emergency. After medical treatment, Sun students wound centralized in the face head and neck, face, a **** there are more than ten places, the right side of the jaw skin was blown into a small finger deep hole. Song person in charge of surgical treatment to open the incision found Sun students neck vascular sheath has been opened, and then deeper 0.2Mm will have a life-threatening. Finally, in the care of high-precision cooperation with each other, Sun students that night was successfully launched out of the operating room, at this stage has been hospitalized to repair and convalescence.
Glass bottles exploded, the probability of analytical chemistry experiments, nature are not right sure, glass bottles of this thing biochemical ring material of each professional are a large number of applications. This time the explosion occurred, if there are clothed with adequate protective gear, negative injuries thoroughly can be prevented this burst of specific injuries from the glass bottle after the explosion of glass fragments floating, resulting in a lot of trauma. The most important safety precautions for something like this come from covering the exposed locations of the body. The most obvious of this injury is the blood vessels in the neck, general clothing pants are not easy to cover the head and neck, be sure to wear a jumpsuit protective clothing only. Semiconductor materials \ microelectronics professionals to do experiments, are going to wear clean room protective clothing, wear masks, wear protective glasses, on the one hand, to avoid the human body on the unclean things flowing out into the natural environment of the laboratory, the chip manufacturing leads to environmental pollution. On the one hand, can also maintain the experimental staff, blocking damage from the outside world.
While that kind of protective equipment in the semiconductor chip industry has been very popularized, but according to what I know, today's biochemical environmental materials laboratory in our country, to the trainees to configure adequate protective equipment in the laboratory is still very few. In many cases, trainees are dressed in civilian clothes to conduct experiments, which is very dangerous in case of accidents. We hope that students will raise their awareness of safety precautions and take the initiative to ask their instructors to purchase protective equipment. If the instructor is not willing to do so, you should pay for it as much as possible to ensure the safety of your life and health in the experiment.
The other responses coincidentally mentioned the obligation of the tutor/research group, which I thoroughly agree with. As a laboratory safety responsibility, the mentor has the responsibility to master's degree doctoral students to carry out safety education, have the responsibility to give the necessary safety measures, but the laboratory safety can not be completely rely on the mentor to complete, which is neither specific, neither objectivity in terms of protective clothing, highly recommended for organic chemistry laboratories to apply even yoga body type of protective clothing, as if a little bit of overthinking. To understand the organic chemistry laboratory after an explosion is likely to cause fire accidents, the semiconductor industry is not a one-piece suit protective clothing can be achieved fire safety regulations, it is likely to have to make a question to take a step back, even if the fire safety regulations can be achieved, the use of such protective clothing period of time how long? In the hot and humid Guangdong, how to ensure that the master's degree doctoral students doing experiments want to spend time to take off and put on such a heavy dress pants? In my personal experience growing up, it seems that not all laboratories can ensure sufficient coolness in the hot summer.
Some master's degree students are not even willing to bother with the usual white coat overalls, this kind of high standard of protective clothing, it is likely to be unable to escape as a pendulum of fortune Therefore, there is no need to put any of the responsibilities of the tutor on the body of a person, in the current environment of the university, the tutor is often put into an unsuitable position, do what must be done. Many colleges and universities are considered to be the one that "both want the horse to run, but do not give the horse to eat grass," the character of the laboratory hardware facilities, if indeed strict compliance, I am afraid that a small half of the university laboratories are more or less do not meet the safety regulations, or in the case of expanding the enrollment of the operation of overloaded year after year. For colleges and universities to be the main actors in the professional opening of the physical and mental health and safety department, on time to carry out laboratory inspection, the effectiveness of this overseas implementation of the work of a long time experience, but in our country has not been followed up on the learning and training
In the past two decades, the total number of undergraduate graduates of China's universities soared from 2.1 million in 2000 to 9.15 million in 2019, the total number of undergraduate graduates has increased from 2.1 million to 9.15 million. On top of that, the total number of postgraduate exams in laboratory-related programs (e.g., science sensible, engineering programs, agriculture and medicine) has risen drastically from 90,000 to 5.3 million. The enhancement in enrollment and total number of scientific organizations has rapidly expanded the total number of laboratories in the country. Along with the increase in the number of laboratories, thus causing more and more major accidents, it has revealed many problems such as insufficient laboratories, unscientific rational layout, improper management methods, untimely awareness of safety precautions and so on. This kind of problem produces an important test for the safety of university laboratories. In the past decade, the important laboratory safety accidents revealed a series of problems in college laboratory safety management methods are not appropriate.
In recent years similar laboratory safety accidents news reports many December 18, 2015 at 10:10 am up and down, Tsinghua University, Department of Chemistry, He Tim Building, a laboratory on the second floor of the explosion accident safety accidents, a doctoral student who has been doing experiments on the scene unfortunately died.September 21, 2016, Shanghai Songjiang University Park, Donghua University, chemical, chemical and biological College of Chemical, Chemical and Biological Engineering, a laboratory explosion accident, two college students suffered injuries, a trainee suffered minor injuries. One of the injured trainees was Guo Hongzhen, a trainee of the class of 2015, who was finally awarded compensation by the institution recently. Guo Hongzhen suffered significant permanent damage to his eyes and face in the safety accident.
On December 26, 2018, an explosion ignited the Municipal and Environmental Engineering Laboratory at Beijing Jiaotong University, and the safety accident resulted in three deaths. The key cause is actually due to the staff concerned in the laboratory in violation of the provisions of the storage of experimental raw materials, resulting in trainees in the whole process of the experiment caused ignition, resulting in serious harm.2021 October 24, Jiangning District, Jiangning District, Dajiangda Road, No. 29, Nanjing University of Aeronautics and Astronautics, Dajiangda Road, teaching area of a laboratory to produce an ignition explosion,*** resulting in two deaths, nine people were injured. This happens to be after the college entrance examination, immediately stepped into is the length of the volunteer, this kind of thing laboratory accident news reports have become a new biochemical ring material new closed pit raw materials.
Safety is a serious and meticulous science and reasonable, do not attach great importance to will be penalized, uncertainty only tragedy appeared in who. I am still practicing hazardous chemicals in the case of work, the actual operation of different equipment have different PPE (safety protective clothing) regulations, the main is the jacket, jeans, shoes and protective glasses, there are some commodities or the actual operation must be equipped with a mask. PPE is the most basic standard into the industrial zone. People are only warehousing and logistics, not carrying out all manufacturing and reflections. But the laboratory is to carry out the use and chemical reaction, for different grades of experiments should have safety regulations.
The core concept of safety is that all safety accidents can be prevented, but the premise is that there is sufficient capital investment. This capital investment includes both mandatory equipment, machinery and equipment, flexible safety management and learning and training, and its development of operating methods to reduce the efficiency. Therefore, the basic law of safety is actually the basic law of money, how much money is invested, how much the failure rate will be reduced. If a laboratory invests too little money in safety, then safety accidents are a certainty, an uncertainty just who then tragedy strikes.
While colleges and universities and competent institutions widely have perfect laboratory safety standardized management, but also on the relevant experimental staff to set the conditions of access to rules and regulations, but the operation of a full-time safety officer configuration is not enough, and its greater scientific research work pressure, also prompted some of the university laboratory management methods are sloppy, step by step, such as non-standard problems. Ensuring the safety of college laboratories is a matter of safety precautionary awareness in the natural environment of scientific research.In June 2019, the Ministry of Education issued the Opinions on Strengthening Laboratory Safety in Colleges and Universities, which emphasized that college and university laboratories are large in scale, many types, and have a wide range of safety risks, including hazardous chemicals, microorganisms, and explosives of raw materials of easy-to-control drugs, and that the potential risks of accidents and staff are more centralized, with cumulative effects. Safety hazards have a cumulative effect.
It is recommended that the construction of institutions, secondary units, laboratories, three-level linkage of laboratory safety management methods obligatory management system; the creation of safety risk management rules and regulations, the laboratory of the teaching and research activities to be carried out on the theme of risk assessment. Universities in the pursuit of perfect new innovation points, to have the security field of expertise and learning and training as a support point. It is necessary to create a university safety supervision system, especially in the centralization of the supervision of major sources of danger, the risk components and risk dynamics in the independent innovation links, to carry out risk identification. In addition, from the mechanism must also be given to the young scientific and technological personnel sufficient sense of belonging, to ensure that the rules and regulations are reasonable and landing type.
Almost any safety incident, the source of all negligence and carelessness, a small mistake, a little carelessness for teachers and students are likely to be serious. Safety first, all teachers and students need to let the safety awareness of the heart, follow the relevant rules and regulations of the laboratory, according to the safety procedures to minimize the risk of experiments, tighten the safety of this string does not slacken, together to prevent laboratory safety and security accidents. Carry out risky experiments, remember a standard - safety first, life first, other are secondary.
