Understand and understand common accident emergency treatment measures and solutions such as burns, burns, chemical poisoning, electric shock, and fire.

Emergency treatment, understand first aid measures

The laboratory building of the university should be equipped at a suitable location. Understand the locations and usage methods of fire hydrants, fire extinguishers, fire blankets, sand boxes, sprinkler devices, eyewash devices, etc., so as to ensure that personnel can rush to emergency facilities in the event of an accident. Every laboratory in a university laboratory should be equipped with commonly used emergency treatment facilities and medicines in line with the characteristics of the laboratory; the person in charge and management personnel of the laboratory must regularly check and maintain, and start the laboratory eyewash every week. Room sprinklers, etc., clear to ensure that the facilities can be used normally.

Question 1: How to recognize and understand the extreme importance of laboratory safety?

In recent years, laboratory safety accidents in domestic and foreign colleges and universities have occurred frequently, and laboratory safety has become a topic of great concern to colleges and universities. Once a safety accident occurs in the laboratory, the normal order of teaching and scientific research will be affected, the lives of teachers and students will be threatened, and in severe cases, it will bring immeasurable losses to individuals, families, schools and society. There are a large number of laboratories in our school, many sources of danger are involved, and various safety hazards still exist. Among teachers and students, there are weak safety awareness, and there are many people who are lucky. Ensuring laboratory safety has become the top priority of the school.

Question 2: What are the main security risks faced by various laboratories in our school at present?

Based on the discipline tradition and professional characteristics, most of the science and engineering laboratories in our school involve hazardous chemicals, hazardous waste, pressure gas cylinders, special equipment, radiation equipment, biological reagents, high-temperature and high-pressure equipment and other hazard sources. Limited experimental space cumulative superposition. In terms of human factors, there are currently a considerable number of private purchases of dangerous chemicals in the school (and no consumption records, storage not in accordance with regulations), random dumping of hazardous waste, mixed release of pressure gas cylinders, unattended experiments, and failure to follow regulations operation and other dangerous behaviors.

Question 3: What deployment arrangements does the school have for laboratory safety work?

The school attaches great importance to laboratory safety work, and has determined 2015 as the laboratory safety year and planned and arranged a series of activities to build a comprehensive laboratory safety work system. A series of documents such as the “Regulations on Laboratory Technology Safety Management” have been formulated and issued, and a three-level management system of schools, colleges, and laboratories has been established, and the responsibilities of each link in the level-by-level responsibility system have been clarified. The next step will be to strictly implement three-level safety inspections, increase rewards and accountability, fully implement the laboratory access system, set up laboratory safety courses, and improve safety prevention hardware facilities. In the future, the school will hold a laboratory safety work conference every year, and will make unremitting efforts to focus on laboratory safety and create a laboratory culture atmosphere in which safety is paramount.

Question 4: What responsibilities does the college undertake in laboratory safety work?

The college is a key link in the three-level management system of schools, institutes, and laboratories, and is the specific implementation unit for laboratory safety responsibilities. The college shall be responsible for formulating the “Safety Management Measures” and “Emergency Contingency Plan” and “Education Training and Access Plan” of the unit. Implement the safety responsibility system step by step, and sign the “Laboratory Safety Responsibility Letter” with the laboratory (responsible teacher). Organize safety education and training, conduct regular safety inspections and supervise rectification. Have the right to punish behaviors that violate the laboratory safety management regulations, and the leaders of the school should bear the leadership responsibility if they fail to fulfill their responsibilities and cause safety accidents.

Question 5: What are the responsibilities of teachers in laboratory safety work?

Teachers are role models for students, pioneers and role models for laboratory safety. The responsible teacher of the experimental room is the main body to implement the specific work of laboratory safety, and is an important link in the laboratory safety responsibility system. The responsible teacher of the experimental room must undertake the responsibility and obligation of conducting safety education and training for the experimental personnel and informing the hidden dangers, and must sign the “Laboratory Safety Responsibility Letter” with the personnel entering the laboratory. At the same time, it is fully responsible for the improvement of the laboratory system, safety inspection and hidden danger rectification. Teachers should bear corresponding responsibilities if they fail to fulfill their responsibilities and cause safety accidents.

Question 6: What role do students play in laboratory safety?

Cultivating the concept of lifelong safety is an important goal of personnel training in colleges and universities. Students are usually at the forefront of laboratory safety, victims of most laboratory safety accidents, and also beneficiaries of the implementation of laboratory safety responsibilities. They must not only be responsible for their own safety More importantly, they should be responsible for the safety of others. Of course, they have the right to make suggestions and opinions on potential safety hazards in the laboratory and have the right to refuse to enter laboratories with potential safety hazards. Students are obliged to accept safety education and training at all levels, understand various potential safety hazards and emergency protection measures, and be familiar with and abide by the internal rules and regulations and operating procedures of the laboratory.

Question 7: How to ensure safety in daily study and work in the laboratory?

When studying and working in school, you should always maintain a sense of safety, strictly abide by the access control regulations when entering and leaving the laboratory, and do not mess with the laboratory. Comply with the daily management regulations of the laboratory, do not eat, drink or engage in recreational activities in the laboratory, do not use open flames, and do not stay overnight in the laboratory. Before the experiment begins, formulate the experimental plan, wear appropriate protective equipment, and fix loose hair and clothing. Follow the operating procedures during the experiment, do not leave the post without authorization, two people are on duty for dangerous experiments, and two people are on duty for overnight experiments. After the experiment is over, turn off the equipment, air source, water source, power supply, doors and windows, etc. in time.

Question 8: What are the rewards and penalties for laboratory safety in schools?

The school laboratory safety work will adhere to the principle of “combination of rewards and punishments”, linking laboratory safety with the unit’s individual annual assessment, awards, job evaluation, promotion, and implementation of a “one-vote veto system” for major accidents. In the next step, the school will set up advanced collective awards and advanced individual awards, establish benchmark laboratories, and support research on laboratory safety. At this stage, it is also very necessary to increase accountability for hidden dangers and accidents. According to the “Interim Provisions on Accountability”, individuals can be given administrative sanctions of expulsion, and laboratories can be punished by closing their doors.

Question 9: What investment has the school made in improving laboratory safety hardware conditions?

Under the existing conditions, it is very necessary to improve the hardware conditions of laboratory safety precautions. At present, the school has equipped all 1,100 gas cylinders with gas cylinder racks, and equipped some laboratories with special cabinets for dangerous chemicals. Ventilation and purification projects of Lixue Building and other buildings. In the near future, the installation of laboratory nameplate information will be launched, some laboratories will be equipped with protective facilities such as emergency showers, eye washers, and first-aid kits, and personal protective equipment will be distributed to students majoring in different disciplines. In the next stage, we will continue to promote the renovation of building ventilation and purification, and formulate and implement plans for the configuration and installation of safety gas cylinder cabinets, special cabinets for hazardous chemicals, and small waste liquid collection devices.

Question 10: How to deal with emergencies in laboratory safety accidents?

Both the school and the institute must establish an emergency system and formulate the “Laboratory Safety Accident Emergency Plan”, and the laboratory should incorporate the accident emergency response method into the corresponding operating procedures and make it clear. Once a laboratory safety accident occurs, keep calm, adhere to the principle of first discovering, reporting, and processing quickly. The on-site personnel or the accident unit must decisively take effective measures to prevent the spread of the situation, report the accident-related situation to the Security Office, the Assets Office, and the school hospital as soon as possible, and at the same time activate the emergency plan of the accident unit. After receiving the accident report, the relevant departments should report it in time and start the school’s emergency plan.
