Summary of experimental safety work 1

We have overcome many difficulties since the establishment of the laboratory. Through continuous study, summary and improvement, we have gradually explored a systematic, perfect, scientific and standardized safety management model. Since it was put into production, there has not been a safety accident. In the past 20xx years, laboratory safety production has always implemented the policy of safety first and prevention first, firmly established the consciousness that safety responsibility is more important than Mount Tai, conscientiously implemented the spirit of meetings and documents related to safety production at higher levels, followed the principle that safety production work is horizontal to the edge, vertical to the end, responsibility goes to people, and no dead ends are left, carried out major inspection and rectification activities for laboratory safety production, further improved the safety production system, established and improved the responsibility system for safety posts, and strengthened supervision and inspection. Work safety in 20xx is summarized as follows:

First, strengthen supervision and inspection and implement post responsibilities.

Doing a good job in production safety is an important, long-term and arduous task, and it is also a regular work. We should always keep a clear understanding of the seriousness of production safety. This work can only be strengthened and must not be relaxed. We must wake up the alarm and make unremitting efforts. The laboratory always regards this as the top priority of all work. Conduct safety training for laboratory leaders and management personnel every year, strictly implement the provisions of the responsibility system for production safety at all levels and the accountability for safety accidents, effectively implement the safety work to the posts and responsible persons, and implement the responsibility system of who is on duty, who is responsible, who operates and who is responsible. For the key parts of the laboratory, personnel and posts shall be assigned, safety inspection shall be conducted regularly, hidden dangers shall be dealt with in time, and all kinds of accidents shall be effectively prevented. 1 of each month is designated as the laboratory safety inspection day. Requirements for inspection: First, the inspection is strict, and problems will not be accommodated. The security work is rain or shine, and people patrol everywhere. Strict requirements, serious treatment, so that the accounts are consistent with the facts, equipment and safety facilities are in good condition, the situation is detected on schedule, and management norms are in place. Strictly rectify the problems found and never tolerate them. The second is to highlight key points and ensure pertinence. During each inspection, according to the operating characteristics of laboratory instruments, climate change and different requirements for safety work in different periods, the inspection focuses are listed, and targeted inspections are carried out, especially for accident-prone points and hidden dangers. Security inspection should not only check the problems, but more importantly, solve the problems and eliminate potential safety hazards. We have seriously rectified all the hidden dangers found in the safety inspection and reviewed the rectification situation. In addition, we also carry out safety publicity activities to promote fire safety knowledge to students and improve their safety prevention and self-help ability. In the safety supervision and inspection, it is mainly aimed at the parts that are prone to safety problems. First, check the power supply of the laboratory; The second is to check the stacking of materials; The third is to check the implementation of safety measures and rules and regulations; Fourth, check all kinds of instruments and equipment; Fifth, check whether the fire-fighting facilities and equipment are safe and effective; Sixth, whether safety education is implemented and whether safety awareness is deeply rooted in people's hearts; Seventh, check the implementation of hidden dangers rectification, find problems in time and eliminate hidden dangers.

Second, strengthen preventive measures to improve safety.

In strengthening safety management, we always adhere to the policy of "prevention first" and take corresponding measures. At the same time, we have also formulated a duty system for key parts and large holidays, so as to be prepared. Every year, professionals are invited to carry out fire-fighting knowledge training, hold fire drills, improve the awareness of prevention of faculty and students, enhance rescue ability, and conduct laboratory safety rules and regulations examinations for freshmen who have just entered school. Those who pass the exam can enter the laboratory to do experiments.

Three, intensify efforts to take effective measures to make the work of production safety solid and effective.

In 20xx, starting with strengthening the basic work of safety production, the laboratory formulated safety technical measures, emergency plans for handling major safety accidents, and rectification measures for hidden dangers of safety accidents, striving to implement the work of safety production. Throughout the year, the laboratory organized safety self-inspection activities 12 times, and found two hidden dangers, all of which were rectified in time, with the rectification rate reaching 100%, and attached great importance to every laboratory with potential safety hazards.

Four, seriously carry out the "safety education day" activities.

June is National Safety Education Month. In order to let more people know and master safety laws, regulations and safety knowledge, the laboratory stepped up publicity, vigorously advocated the concept of safety development, and launched a safety education month with the theme of "safe production and comprehensive management" to vigorously publicize the importance and necessity of safe production.

Five, enhance the sense of responsibility and urgency, safety management has a long way to go.

Every safety regulation in the laboratory is the golden rule. Remember it, obey it and fear it. Any overstepping may pay the price of blood Safety accidents happen from time to time, and major liability accidents have become an increasingly heavy topic at present. The main reason is that the relevant responsible persons do not abide by laws and regulations in their work, and in order to achieve the so-called "high efficiency", they ignore safe production, lax management and carelessness. Therefore, it is a long way to go to conscientiously implement the laboratory safety regulations and do a good job in safety production management. Conscientiously implement the spirit of the 16th National Congress of the Communist Party of China, take the full implementation of the Law on Work Safety as the main line, adhere to the policy of "safety first, prevention first", set out to establish a long-term mechanism for work safety, strengthen supervision according to law, and let the concept of "safety first" penetrate into the hearts of every faculty member, so that everyone can clearly understand their rights and obligations in work safety given by law, learn to use the rights given by law to protect their personal safety, and have the responsibility to fulfill the laws. Only in this way can everyone ensure everything is safe.

Summary of experimental safety work II

Safety first and prevention first is the policy of safe production in China. For those of us who often haunt the laboratory, we must constantly improve our safety awareness. Rich safety knowledge, strict compliance with operating rules and regulations, and constant vigilance can avoid accidents. If the preventive measures are reliable and the accidents are handled properly, the losses can be minimized.

Specific laboratory safety rules mainly include the following aspects:

Safety problems such as types of laboratory safety accidents, laboratory safety management, first aid treatment, fire, fire prevention and extinguishing, fire evacuation and escape, safety of dangerous chemicals, use safety of gas cylinders and pressure vessels, types of radiation, hazards and protection.

After a semester of laboratory safety research, I came to the following conclusions:

I. Key points of safety management.

1, adhere to the policy of "safety first, prevention first".

2. Strengthen the construction of safety work system: safety management responsibility system, safety publicity and education system, campus safety information reporting system, hidden danger rectification management measures, emergency plan for serious and serious safety accidents, emergency plan for public emergencies, and reward and punishment system for school safety target management.

3. Do a good job in the investigation and rectification of potential safety hazards.

Second, the types of laboratory hazards.

1, fire and explosion hazard.

The fire risk in the laboratory is universal, because the analytical chemistry laboratory often uses flammable and explosive materials. High-pressure gas cylinder, low-temperature liquefied gas and decompression system (vacuum drying, distillation, etc. ), if it is not handled properly, it will be impossible to operate, and then it will encounter high temperature, open flame, collision, container rupture or failure to meet the safety protection requirements, which will often lead to fire and explosion accidents, ranging from personal injury and equipment damage to casualties and house damage.

2. Danger of toxic gas.

Gases and various organic solvents are often used in analytical experiments, which are not only flammable and explosive, but also toxic. In some experiments, toxic gases are also produced due to chemical reactions. If you don't pay attention, it may lead to serious poisoning.

3. Danger of electric shock.

The analysis experiment can not be separated from electrical equipment, not only the low voltage of 220v is commonly used, but also the high voltage of thousands to tens of thousands of volts. Analysts should know how to prevent electric shock or explosion accidents caused by using non-explosion-proof electrical appliances.

Third, fire prevention and anti-detonation measures.

According to the causes of fire and explosion in the laboratory, the following targeted preventive measures can be taken.

1, to prevent heating fire

(1) Flames, electric heaters or other heat sources are prohibited from placing flammable materials.

(2) The heaters such as alcohol lamps, blowtorches and electric furnaces for heating should be turned off immediately after use.

(3) Hot items cannot be placed directly on the experimental platform, and heaters with higher temperature such as various electric heaters should be placed on the asbestos board.

(4) When pouring or using flammable materials, there shall be no open flame nearby.

(5) When evaporating, distilling and reflowing flammable materials, it is forbidden to directly use open flame or use open flame water bath for heating, and water bath, sand bath or oil bath should be used for heating respectively according to the boiling point.

(6) In the process of evaporation, distillation or heating to reflux flammable liquid, the analyst shall not leave without authorization.

(7) Too much flammable materials should not be stored in the laboratory.

(8) Explosive substances should not be stored in glass bottles with grounding plugs to avoid explosion due to friction when closing or opening the glass plugs. Cork plugs or rubber plugs must be used and kept clean.

(9) When accidentally dumping flammable materials on the test bench or on the ground, you must:

(1) quickly disconnect the heating sources such as electric furnace and blowtorch nearby.

(2) Immediately use towels and rags to absorb the liquid.

(3) Indoor ventilation immediately.

(4) When the body or hands are stained with flammable materials, they shall be cleaned immediately and shall not be near the heat source.

2, to prevent chemical reaction fire or explosion

(1) For the experiment to be carried out, the staff must know the characteristics of the reaction and the chemical reagents used. For dangerous experiments, appropriate protective measures and accident handling methods should be prepared.

(2) The experimental operation of inflammable and explosive articles should be carried out in a fume hood, and the operators should wear rubber gloves and protective glasses. 3 Destroy the remaining inflammable and explosive articles in time.

(3) Prevent explosion caused by pressure difference between inside and outside the container.

(1) To prevent the explosion of the decompression device, the pressure difference between the inside and outside of the decompression vessel shall not exceed one atmosphere.

(2) measures to prevent explosion caused by pressure rise in the container.

A substances with low boiling point and easy decomposition can be stored in thick-walled bottles and placed in a cool place.

B, all operations must be carried out in accordance with the operating procedures. When the reaction is too intense, appropriate measures must be taken to slow down the reaction. C. Don't install the instrument by mistake, which will form a closed system during the heating process.

C, may explode experiment must be cautious, strict management, strictly abide by the operating procedures. It is absolutely forbidden to operate by people who don't understand the experiment, and it is strictly forbidden to work alone in the laboratory.

3. Fire fighting in the laboratory.

(1) Fire extinguishing principle:

Remove or isolate the fuel source, isolate the air (oxygen) and reduce the temperature. According to the fire caused by different substances, different fire extinguishing methods are adopted.

(2) Laboratory fire emergency measures:

(1) To prevent the fire from spreading, first cut off the power supply and extinguish all heating equipment; Quickly remove nearby combustibles; Turn off ventilation equipment to reduce air circulation.

(2) immediately put out the flame, try to cut off the air, so that the temperature drops below the ignition point of combustible substances.

(3) When the fire is large, a fire extinguisher can be used. The selection of fire extinguishers should be based on fire types and different fire extinguishing mechanisms.

A water, foam, ammonium phosphate dry powder and halon fire extinguishers should be selected to put out Class A fires.

B. Dry powder, foam, halon and carbon dioxide fire extinguishers shall be used to extinguish Class B fires. Chemical foam extinguisher is used to put out Class B fires with polar solvents, because when polar solvents such as alcohols, aldehydes, ketones and ethers come into contact with chemical foam, the water in the foam will be quickly absorbed, which makes the foam disappear quickly, so it cannot play a fire extinguishing role.

C, class C fire, should choose dry powder, halon, carbon dioxide fire extinguisher.

D halon, carbon dioxide and dry powder fire extinguishers should be selected to put out the fire on site.

Personally, as far as students in our college are concerned, the biggest safety hazard is fire. Therefore, I think it is necessary to give appropriate fire safety training to laboratory personnel, so that everyone can master the use of fire extinguishers and how to take the correct methods in case of fire, so as to minimize property losses and casualties.

But in fact, most students didn't pay attention to it in the usual experimental process, and even felt that it had little to do with themselves after realizing some security risks. These bad habits are not only bad for laboratory safety, but also have a very bad influence on scientific research. For example:

1, laboratory articles are in a mess, and experimental articles are mixed with personal articles, which has caused many adverse effects on daily study and life. All kinds of articles should be classified and put in a fixed position to reduce unnecessary troubles.

2. The sanitary condition of the laboratory is worrying, and the phenomenon of littering peels and scraps of paper is common. Often the garbage can is full and untreated, and it will give off an unpleasant smell when the weather is hot, which provides a hotbed for the spread of diseases. Recently, the laboratory duty schedule has been made, and the situation has improved at a fixed time every week, but the key is to stick to it.

3. The layout of various experimental instruments in the laboratory is unreasonable. Some students often mix the workbench with the experimental platform, and the noise during the experiment will affect the work efficiency. In addition, because the former classmates piled up a lot of books and sundries in the laboratory, and some sundries were pressed on the circuit lines, if they work for a long time, they will easily catch fire, so they should pay attention.

Some students like to put breakfast snacks and other things in the laboratory, or eat them directly in the laboratory. Some smells are difficult to disperse, which will affect other students' study and work, and also attract rats and cockroaches, causing property losses to students. More importantly, if the experimental drugs are accidentally scattered in food, it may cause food poisoning, which is not good for the health.

Some students didn't put the experimental drugs back after the experiment, but put them in their favorite places at will. Although this may be convenient for your own experiment, it will bring trouble to other students who use this drug.

6. During the experiment, some students don't like to wear lab clothes, plastic gloves and other protective equipment. Doing this experiment is risky, and laboratory personnel should supervise each other and remind each other to avoid accidents.

This phenomenon is not uncommon. As an experimenter who often has to deal with laboratories, he must pay attention to them, learn from them and always be alert to his own safety problems. Security risks are hard to prevent, and only personal attention can really put an end to the danger.

Appropriate laboratory safety education should be given to students. By learning the necessary safety knowledge, safety management and operation precautions, students' safety awareness and quality can be improved, and laboratory safety accidents can be reduced and eliminated. The ultimate goal is to make every student strictly master and conscientiously implement the relevant requirements of the laboratory, such as safety system, instrument management, drug management, glassware management system and so on. In addition, we should not only strengthen fire awareness in theory, but also learn some necessary first aid and self-help knowledge in practice to create a safe and harmonious learning and research environment.

Summary of experimental safety work 3

According to the relevant requirements of the school, our hospital has comprehensively strengthened laboratory safety management and established a laboratory safety leading group, with the hospital leaders as the main person in charge; The college-level safety responsibility system was established, and the safety responsible person was defined in each laboratory. Improve the laboratory safety management system with discipline characteristics; There are experimental instructions or safety operation procedures for equipment and dangerous experiments and processes involving potential safety hazards, and they are clearly stated; According to the hidden dangers of each laboratory, there are corresponding emergency plans; Carry out various safety education activities, and regularly carry out laboratory safety inspection and self-examination. Laboratory chemical reagents are isolated and placed in order as required; Large expensive instruments in the laboratory are maintained and used by special personnel to avoid instrument damage caused by misoperation; Indoor ventilation is good, health standards; Dispose of special waste liquid barrels, and centrally treat toxic and harmful experimental waste liquid; The inventory of laboratory items is completed. Adequate fire fighting equipment, such as fire extinguishers; The fire escape is unimpeded; Do not block fire exits, and do not pile up instruments and articles in public passages; When the laboratory is empty, the doors and windows are locked to ensure safety.

The main problems found in the inspection are:

1. The management of precursor reagents and hazardous chemicals is not perfect, and hazardous chemicals are placed in open test racks.

2. The waste disposal record is incomplete, and there is no classification mark on the waste liquid disposal container.

3. Put flammable items or chemical reagents in a fume hood.

4. Some experimenters didn't wear lab clothes, gloves, goggles and masks.

5. Experimental garbage and domestic garbage are not treated separately.

6. There is a phenomenon of private pull and random connection.

In view of the above problems, the measures taken include:

1. Strengthen the management of hazardous chemicals. Chemical reagents should be classified and kept by special personnel, and controlled hazardous chemicals such as precursor chemicals and explosive chemicals should be stored in special double-lock explosion-proof cabinets, and use accounts should be established.

2. It is required to fill in the waste disposal record in time, and paste the handover form on the back of the record book in time; When collecting new waste liquid barrels, ask the distributor for labels in time; Complete waste disposal records; Waste collection containers should be labeled with classification labels.

3. Remove all organic solvent bottles from the reagent rack. Only non-flammable and explosive inorganic reagents are placed in the reagent rack.

4. Emphasize that experimenters must wear lab clothes, gloves, goggles and masks, and pay attention to personal protection.

5. The experimental garbage and domestic garbage are collected separately and put in different garbage bags.

6. Contact the property for timely maintenance.

All rectification measures have been put in place in time to ensure the elimination of potential safety hazards.

Laboratory safety management is a meticulous, long-term and arduous work, and we will always be vigilant to ensure that the laboratory can serve teachers and students safely.

Summary of experimental safety work 4

Further implement the Regulations on Biosafety Management of Pathogenic Microbiological Laboratories, effectively strengthen the standardized management of laboratory biosafety in our hospital, and ensure the health of the public and laboratory staff. According to the requirements of the higher health department, we have strengthened the management of laboratory biosafety. The biological safety work in our hospital since 20 14 is summarized as follows.

First, strengthen leadership and improve organization.

In order to better implement the various systems and regulations of laboratory biosafety, our hospital has established a leading group, expert group and office for biosafety management of pathogenic microorganism laboratories. The leading group is headed by President Chen Gang, and its members include vice president of business, director of science and education department and director of laboratory. The expert group consists of vice president of business, director of science and education department and director of laboratory. The office is located in the science and education department, and the person in charge of laboratory biosafety is designated to be responsible for the biosafety management of pathogenic microorganism laboratory in our hospital.

Second, establish rules and regulations to provide protection.

In order to strengthen the biosafety management of laboratories, the relevant provisions of the Regulations on Biosafety Management of Pathogenic Microbiology Laboratories were strictly implemented. According to the laboratory situation in our hospital, the Laboratory Biosafety Manual was compiled, and a perfect biosafety management system was formulated, including laboratory personnel admission system, laboratory housekeeping management system, laboratory personnel biosafety code of conduct, laboratory equipment biosafety technical specification, biosafety personnel training, assessment system, laboratory bacteria (virus) species and biological samples safe storage system, and so on. At the same time, emergency plans for biological hazards, infectious diseases after occupational exposure, and leakage of dangerous chemicals have been formulated to provide protection for emergency treatment after biosafety incidents.

Third, the layout is reasonable and the facilities are complete.

According to the requirements of "Regulations on Biosafety Management of Pathogenic Microorganism Laboratories", we reasonably divide the laboratory into polluted area, semi-polluted area and clean area. There is no cross distribution between different areas, and there are windows at the entrance of the laboratory, with biosafety labels and biosafety hazard warnings. At the exit of the laboratory, there are dressing rooms and cabinets for personal belongings. The personal clothes of the staff are stored separately from the laboratory work clothes and supplies. The countertops, walls, ceilings and floors of laboratories can be easily cleaned, impervious to water, and resistant to corrosion by chemicals and disinfectants. The exit of each laboratory is equipped with induction hand washing facilities, the pathogenic microorganism laboratory is equipped with biosafety cabinet and eye washer, and an emergency spray device is installed in the middle of the laboratory channel. At the same time, each laboratory is equipped with sufficient biological safety protection supplies and equipment, the laboratory is equipped with an autoclave, and the laboratory has a reliable power supply. Two of the instruments are equipped with standby power supply, and all the equipment in the laboratory is functional and in good condition, and is regularly maintained. Monitor indoor environmental parameters every morning, and the parameters meet the work requirements and health-related requirements.

Fourth, improve supervision and ensure operation.

According to the requirements of "Regulations on Biosafety Management of Pathogenic Microbiological Laboratories", we conducted a laboratory biosafety risk assessment for hospital laboratories, made clear the hazards and risks of laboratory biosafety, and achieved a good idea. According to the assessment, we provided the necessary biological safety guarantee to ensure the biological safety of laboratory staff.

In order to do a good job in the supervision and management of laboratory biological safety, according to the requirements of superior documents, our hospital appointed two comrades as laboratory biological safety supervisors to supervise and inspect the implementation of laboratory technical specifications and operating procedures. Formulate procedures for feedback and corrective measures for incidents that do not meet biosafety requirements, find and solve biosafety hidden dangers in time, hold biosafety management meetings regularly, sum up work, and continuously improve biosafety management.

Five, comprehensive training, improve quality

In order to standardize the laboratory biosafety behavior of the staff, various forms are adopted to organize the staff of the department to carry out the training in the aspects of "Regulations on Biosafety Management of Pathogenic Microorganisms Laboratory", "Laboratory Biosafety System", "Biosafety Emergency Plan", "Personal Safety Protection of Laboratory" and "Laboratory Standard Operating Procedures". , and conduct regular evaluation. Through the comprehensive and systematic training and examination of all kinds of biosafety knowledge at all levels, the laboratory biosafety awareness of department staff has been strengthened, the biosafety behavior of laboratory staff has been standardized, and the implementation of various biosafety systems has been ensured.

Six, strengthen management, standardize behavior

Every year, the laboratory conducts laboratory biosafety assessment for its staff, and requires the staff to pass the examination and obtain the qualification. At the same time, laboratory personnel conduct health check-ups every year, and establish health records of laboratory personnel. All laboratory activities conform to relevant national standards, technical specifications and operating procedures. Non-experimental articles are not allowed to enter the laboratory, the protection level of experimental operators meets relevant regulations, and laboratory waste disposal personnel need to be trained in relevant knowledge before taking up their posts.

All samples in the laboratory were taken from clinical patients and hospital infection monitoring samples. After use, the specimen is temporarily stored in a special specimen preservation refrigerator, and the hepatitis B positive specimen is frozen, but the pathogenic microorganism (virus) species are not preserved. The samples that have reached the shelf life and the microbial samples after the experiment are sterilized by high pressure steam and treated centrally.

Only standard strains for indoor quality control of microorganisms are stored in the laboratory, and kept in the freezer at -86℃, and a special person is appointed to be responsible for the preservation of strains, so as to ensure the safety of strains, and a list of preserved strains is established and strictly registered, including the date of purchase, use, destruction, destroyer, method and quantity.

The garbage and wastes produced in the laboratory strictly follow the principle of classified collection, and there are internal handover records. High-risk wastes such as culture medium, specimen and strain preservation solution of pathogens in the laboratory are sterilized by high-pressure steam indoors before being discarded. Laboratory equipment should be cleaned, disinfected and sterilized before maintenance, repair, scrapping and transportation out of the laboratory. The waste liquid produced by the experimental equipment is treated harmlessly, and the waste water and waste gas discharged from the laboratory meets the national regulations.

The above is a brief summary of the laboratory biosafety work in our hospital since 20xx. In the future, in accordance with the standards of the Regulations on Biosafety Management of Pathogenic Microbiological Laboratories and the requirements of higher authorities, we should standardize biosafety behaviors, ensure the biosafety of laboratories, provide good services for the overall development of hospitals, and make the work of laboratories reach a new level.

Summary of Experimental Safety Work Chapter V

According to the General Guide for Biosafety of Microbiology and Biomedical Laboratories and the requirements of biosafety management of laboratories in Hebei Province, especially the requirements of the national and provincial video conference on disease prevention and control on July 8, in order to further implement the relevant regulations on laboratory biosafety, we have mainly done the following work:

First, strengthen leadership and improve organization.

In order to better implement the various systems and regulations of laboratory biosafety, the party group of the Standing Committee decided to set up a biosafety management committee, with Comrade Dou as the director, Zhu Fengchao and Chen Yanqing as deputy directors, and Ge,,, and Huo Jianguo as members. Various management systems and safety systems of laboratory biological safety have been formulated.

Second, the system is implemented and measures are in place

Various biosafety related systems have been formulated, including laboratory management system, microbiological laboratory work system, aseptic room operation system, microbiological laboratory disinfection and isolation system, laboratory biosafety management and guarantee system, laboratory accidental pollution accident handling system, bacteria and virus strain preservation management system, drug reagent management system, highly toxic drug management system and waste disposal system.

The third is to check and evaluate and rectify in time.

On July 26th, the Biosafety Committee conducted a self-examination and inspection of the unit and the stations under its jurisdiction. Summarize after the self-inspection and put forward effective rectification opinions and measures (with self-inspection table and inspection content table attached). Through self-examination, we found out the existing problems and gradually improved our biosafety work.

Fourth, do a good job in training and improve quality.

In order to further improve the change of the city's health inspection personnel's understanding of biological safety, according to the requirements of the station leaders, a study class with biological safety management and food poisoning treatment as the main contents was held from May 13 to May 16, with the participation of inspection personnel from all counties and stations. Director Dou put forward specific requirements on the importance of biosafety work and biosafety work. Through the study, the laboratory biosafety awareness of the city's inspectors has been improved, and the concept has changed, which has played a certain role in doing a good job in biosafety. In August, we plan to hold a biosafety symposium attended by the heads of inspection departments of cities, counties and districts. The plan has been made and the leader has approved the unfinished work.

Verb (abbreviation of verb) implements the system and regulates management.

We should establish a management system for the preservation of strains and highly toxic chemicals, do a good job in preservation and custody in strict accordance with the management system, and do a good job in registration. Special storage facilities should be set up, locked and kept by two people, strict approval and use procedures should be formulated, and registration records should be kept.

Six, strengthen safety awareness, eliminate potential safety hazards

In order to prevent experimental pollution accidents and make preparations, we have formulated operating rules for laboratory pollution and waste disposal, and strictly followed them to prevent pollution accidents caused by improper waste disposal. Once it happens, do it in strict accordance with the handling regulations.

There is a problem:

First, the strain preservation system is not perfect.

Second, although the leaders have made great efforts and inclinations, due to economic problems, the sampling equipment and untrustworthy reagents for public health incidents can only be basically achieved. I hope that the superior leaders will reflect more and strive for policy support.

Third, the formulation of biosafety measures should be further improved.
