Laboratory safety management is not only related to the smooth progress of scientific research and teaching, but also related to the life safety of laboratory personnel. As we all know, the laboratory is mostly used for analysis and testing, product testing, and teaching, scientific research, small test, etc. Its characteristic is chemicals, actual variety, quantity is relatively small, analytical instruments, such as centrifuge, sterilization pot experiment equipment, and involves the gas cylinders, such as gas chromatography used in air, nitrogen, hydrogen and argon and helium gas, liquid chromatographic using mobile phase, such as methanol, acetonitrile, etc., are all belong to the dangerous chemicals. Accidents caused by chemical leakage, pollution and explosion due to man-made or spontaneous combustion are called chemical accidents. According to statistics, chemical accidents in the laboratory account for the majority of the total laboratory accidents.
An unknown white solid in a flask left by a former graduate student in a laboratory at a university in Guangdong province exploded while a doctoral student was washing it with water on July 27, according to a safety incident. Shards of glass from the burst punctured an artery in the child's arm. Subsequently, the student has been sent to the hospital for treatment. The injuries are under control and are not life threatening.
On The morning of July 24, an explosion occurred in a chemical laboratory of a glass factory in Jishui County, Ji 'an City, Jiangxi Province. It is reported that the explosion was caused by the improper operation of the chemical laboratory experimentered, which caused the air shock, resulting in a small explosion, the accident eventually resulted in one death and one minor injury.
Summer, university laboratory renovation, adjustment and relocation, teachers and students, especially graduate students to carry out scientific research and innovation and entrepreneurship activities are relatively concentrated, so will enter or enterprises or factories to participate in the laboratory research, in the face of unfamiliar environment and experimental operation, we must always pay attention to safety. So how should the laboratory carry out safety management and standard operation!
First, implement grid management
Colleges and universities should improve the three-level linkage safety responsibility system of schools, second-level units and laboratories, further define the responsibilities at all levels and the safety persons responsible for each laboratory, and sign a responsibility letter, establish a grid management list, and build a "horizontal to the edge, vertical to the end, comprehensive coverage, hierarchical management, layer upon layer responsibility" work system.
Two, adhere to the regular inspection
Colleges and universities should adhere to the combination of daily inspection and random inspection, summer key inspection of open laboratories. The school level should be inspected at least twice, the college level should be inspected at least once a week, and each laboratory responsible person should carry out routine inspection every day. All levels of inspection records to keep files for reference, timely elimination of hidden dangers.
Third, strict access system
Universities should strictly register and manage laboratory access, and prevent irrelevant personnel from entering the laboratory. For the teachers and students who stay in the school to carry out the experimental work in summer vacation, they should strictly abide by the experimental operation regulations, keep the laboratory clean and hygienic, ensure the operation of instruments and equipment and the safety of electricity, water and gas, and are strictly prohibited to eat or sleep in the laboratory.
Fourth, carry out safety education
Colleges and universities should carry out a targeted laboratory safety education training and safety emergency drill for the teachers and students who stay in the school to carry out experimental activities in the summer, combined with the characteristics of disciplines and majors, so as to further improve the safety awareness and safety prevention ability of teachers and students.
Fifth, strengthen the control of hazard sources
Colleges and universities should establish and improve the supervision system of the purchase, storage, storage, use and disposal of experimental products such as easy to produce drugs, easy to produce explosives, dangerous chemicals, bacteria (virus) species and pathogenic microorganisms, so as to achieve traceability, complete process and complete closed loop. The experimental sites involving dangerous sources should have clear warning labels. The laboratory should set up a temporary storage area for hazardous waste. Hazardous waste should not be stored in excess in the laboratory and should be transferred to the school's temporary storage. All colleges and universities should timely clean up and dispose of the hazardous waste temporarily stored in the hazardous waste storage during summer vacation.
Vi. Improve the ability of risk assessment
For the reconstruction and relocation of laboratories in summer vacation, universities must strictly examine and approve projects and do a good job of safety risk pre-assessment report; The laboratory safety management department evaluates the guarantee conditions and potential risks of experimental safety. Resolutely put an end to the implementation of unapproved projects.
Strengthening comprehensive coordination
Laboratory safety is related to the overall situation of the school, the relevant departments and units of colleges and universities should take their respective responsibilities, work together to resolve potential safety risks and ensure the safety of summer vacation. The functional departments of teaching and scientific research should do a good job in risk assessment of experimental teaching projects and scientific research projects. The functional department of the laboratory should do a good job in the procurement, storage, use, waste disposal of experimental products; The logistics department should do a good job in fire protection and public security, funds and conditions, network security and other work; The secondary college (scientific research institution) is responsible for the normal operation of its laboratory; Instructors should not only guide students' scientific research activities, but also ensure the safety of students' scientific research activities.
Conclusion:
In order to avoid the occurrence of laboratory safety accidents, before the experiment, the experimenter should be clear about the dangers of the experiment, what accidents may occur, and where the cause of the accident will be. Be clear about the most serious security issues that can occur. What to do in case of an accident. Before the experiment, it should be clear how to experiment the equipment, understand the hazardous characteristics and protection knowledge of the chemicals used in the experiment. And confirm the safety and reliability of instruments and equipment, can be normal operation.
