As the saying goes: safety is higher than life, and responsibility is more important than Mount Tai. Some large analytical instruments in the laboratory need to use high-pressure gas cylinders, so it is necessary to manage high-pressure gas cylinders well, and the storage of high-pressure gas cylinders such as oxygen, nitrogen and hydrogen should meet the requirements of experimental environmental conditions. Establish necessary procedures for the storage and distribution of flammable, explosive and toxic substances, and be familiar with accident handling methods. The following is my self-evaluation of laboratory work. I hope you like it!
Self-evaluation of laboratory work 1
Laboratory work is an important aspect of cultivating students' quality. Therefore, it is an important part of the whole teaching work plan of our school to manage the experimental work well, take the experiment as a breakthrough, stimulate students' interest and improve their quality through experiments. Over the years, the leaders of our school have attached great importance to the construction and management of laboratories, gradually standardized laboratory construction, and formulated laboratory management regulations and various reasonable management systems. The working objectives of the laboratory are put forward: giving priority to teachers, modernizing teaching facilities, standardizing instrument management and informatization of experimental teaching. Promoting construction by evaluation and promoting reform by evaluation have pushed the laboratory work to a new level.
First, give priority to teachers.
Teachers play an important role in the development of students, and the discipline of science education puts forward higher requirements for teachers, which is difficult for ordinary teachers to be competent. Fully aware of this, school leaders have continuously optimized and adjusted the arrangement of teachers, and gradually formed a reliable and high-quality team of science teachers today. In the new curriculum reform in recent years, science teachers in our school have participated in various teaching seminars at all levels.
The second is the modernization of teaching facilities.
School leaders organize scientific research teaching and research groups to study the Standards for the Construction of Standardized Laboratories in Primary and Secondary Schools and the Standards for the Inspection and Acceptance of Standardized Laboratories, and fully realize the importance of evaluation. Scientific laboratories and instrument rooms have been established, and various experimental instruments and specimens have been added. It is no exaggeration to say that with the existing teaching equipment and instruments in our school, students can completely carry out experimental teaching. In addition, multimedia equipment has been added to enrich the teaching methods, which has improved the scientific teaching conditions in our school.
Third, instrument management standardization
Because the school attaches great importance to the management of experiments, the school plans and evaluations are brought into the laboratory every semester, and specific personnel are instructed to implement them. So as to ensure the implementation of various plans. Leading teachers and students to form a * * * top-down management, maintenance and operation? Lifeline? . Let the laboratory run orderly and give full play to its potential functions.
1. Establish a sound management system and strengthen the management of instruments and equipment. Based on the reality, the scientific research teaching and research group has formulated a series of rules and regulations from instrument purchase to scrapping, instrument lending to return. , and timely do a good job of instrument ordering, instrument warehousing, instrument loss reporting and compensation, and often count, classify and dust the instruments. Make the accounts and things consistent, and make the management of fixed assets step into the track of scientific management and modern management.
2. Make good use of natural laboratories and play the role of equipment. We require teachers to effectively play the role of instruments, improve teaching efficiency by modern means, bring a good activity environment for extracurricular scientific and technological interest groups, and cultivate students' innovative spirit and practical potential. Make an experimental teaching schedule at the beginning of the semester and strictly implement it.
3. Experimental teaching is a systematic process, which should pay attention to both process and result.
Fourthly, experimental teaching is informationized.
1. Make full use of resources, absorb advanced teaching ideas, internalize them into our own teaching ideas through a series of activities of teaching and research groups and lesson preparation groups, undertake the activities of municipal scientific research groups with heart, and give full play to the functions of laboratories.
2. Give full play to the function of blog, release the latest and most cutting-edge information on teaching reform, fully encourage students to write experimental diaries, give students a chance to succeed, enhance the information content of students, and publicize and affirm the highlights of school science education in time.
Verb (abbreviation of verb) expands channels and gives consideration to others.
School laboratory work, like other work, is also the main front to promote students' all-round development. In order to promote students' all-round development and cultivate their innovative spirit and practical potential, we also vigorously carry out extracurricular scientific and technological practice activities to build a platform for students to improve their practical operation potential.
1, use the laboratory to organize counseling and participate in the scientific and technological innovation competition.
2. Do a good job in teacher's demonstration experiment and students' grouping experiment, write the necessary experience after the experiment, and help students write small scientific papers. So far, several small scientific papers have won prizes.
At the same time, our school also gives full play to the intelligence of science teachers and devotes itself to expanding and developing other scientific and technological activities. The school has excellent management, excellent academic performance and outstanding students' achievements. However, this is far from our ultimate goal, but only the first step of the long March. I believe that our laboratory management will go to a higher level and the efficiency of our laboratory will be better.
Self-evaluation of laboratory work II
I have been engaged in laboratory work for more than thirty years. In the work, closely around the company's central task, based on laboratory work, conscientiously perform their duties, in this ordinary post conscientious, hard-working. Study hard and work hard is my working principle.
So we have mastered the first-hand testing technology. And under the care and guidance of leaders and colleagues, through their unremitting efforts, all aspects have made necessary achievements and improvements, and now they have become technical veterans and operational experts in the workshop. Now my work scene is determined as follows:
First, always strengthen self-study, strengthen personal skills and improve professional quality.
Laboratory work is the lifeblood of the production device, and reliable data supply is the basis for the sales department to speak. Therefore, it is very important to do a good job in the laboratory. As an old laboratory clerk, if you want to do a good job in the laboratory, you must strengthen your study and constantly improve your personal skills and professional level. In practical work, we must have perseverance and perseverance, learn while doing, use more brains and accumulate more. Received a good learning effect.
First of all, we systematically studied the professional knowledge of laboratory testing. After purchasing, borrowing from colleagues, downloading from the Internet, and extracting previous laboratory materials, I earnestly studied and mastered laboratory knowledge and methods, and strived to improve my practical operation and theoretical level.
Second, after learning, I have mastered the theoretical basis, working principle and related operational procedures of various tests.
The third is to learn and remember related management systems, such as laboratory inspection, quality supervision, laboratory drugs, laboratory instruments and equipment, laboratory environment management, etc. Taking the laboratory as the breakthrough point and integrating into quality management. Enterprising to participate in the laboratory technician examination and technical contest organized by the group company, I have increased my knowledge and enriched my experience, thus improving my professional skills and work quality, and obtained the senior qualification certificate of laboratory technician with good results.
Second, be conscientious, objective and rigorous.
As a laboratory technician, I always take a high sense of responsibility, in the actual work process, in line with the objective, rigorous and meticulous principles, in the daily analysis work to be realistic, carefully audited, responsible, and strictly implement laboratory rules and regulations, instrument operating procedures and related quality standards. Strictly review untrue and unreasonable data, resolutely carry out three-level inspection to ensure that the data is correct, and report it if there is no problem.
Third, strengthen safety education and raise safety awareness.
When working in the laboratory, it is very important to have safety awareness and environmental awareness. In practical work:
First, strictly implement the company's various safety regulations to? Do you want to do it? The principle is self-discipline, always put safety first, actively participate in various safety activities organized by the company, persist in grasping safety, explore safer ways, and truly implement safety. Before you go to work, you are required to devote yourself to your work, right? One minute at work and 60 seconds on duty? . Take every job seriously, memorize all safety measures, check the hidden dangers around you, don't panic when something happens, return in time, keep records and stick to your posts.
Second, environmental protection is also very important. Every chemical reagent, waste gas and oil samples that need to be treated should be treated in a centralized and classified manner, and not dumped at will. These have a great impact on the environment. For example, when washing bottles, don't pour oily sewage casually. At the same time, pay attention to the ventilation of the laboratory and the management of various chemical reagents and oil samples, so as to be smooth and tidy.
Fourth, work attitude and hard work.
I love my job, treat every job correctly and seriously, make a personal work plan before starting work, and give priority to completing all tasks in time. Enthusiastic service of all kinds of production equipment, as long as there is a need, I will be proactive, seriously serve everyone, seriously abide by labor discipline, and ensure the timely completion of work tasks.
Style, can abide by the rules and discipline, unite colleagues, seek truth from facts, optimistic, and always adhere to a rigorous and serious work attitude and meticulous work style.
Looking back on the work experience and achievements of these years, it is obvious to all. But there are still some shortcomings in some aspects. For example, there are not many creative ideas, and individual works are not perfect.
In the future work, we must continue to work hard, constantly improve, constantly learn new businesses and technologies, and strictly abide by various rules and regulations, so as to raise our ideological awareness and work efficiency to a new level.
The future work can be expected to be more arduous and demanding, and the knowledge to be mastered is higher and wider. To this end, I will work harder, study hard, and strive to improve my cultural quality and various work skills, so as to meet the needs of higher and newer laboratory work, greet the arrival of 20___ with a brand-new look, and lay a solid foundation for safe production in 20___.
Self-evaluation of laboratory work 3
In 2000, with the strong support and guidance of the center, the testing laboratory fully implemented the second-class company? Big? 、? Fuck? 、? Quick? 、? Going? Qi Xin, a staff member, worked together as one and successfully completed all tasks. The necessary results have been achieved. The main work this year is determined as follows:
I. Major Completion Scenarios
1, acceptance of newly arrived materials
In the past 20 years, all kinds of newly arrived materials were inspected 34 times1time, including wire and cable 198 times, conveyor belt 56 times, petroleum products 60 times, plastic mesh belt 18 times and polymer products 9 times.

At present, the laboratory is responsible for ferrography analysis and moisture test of the oil of 63 teams in use, including the whole mining area 14 mine, 1 1 washing and loading system. Up to now, 395 points have been analyzed, and abnormal points 1390 and 35 serious problems have been found. The detection of abnormal points provides an accurate basis for preventive maintenance of equipment.
The water quality of 222 16 fully mechanized working face in Halagou Mine, shearer in 404 fully mechanized working face in Bulianta Mine and planetary head of left rocker arm of shearer in 205 fully mechanized working face in Shangwan Mine were emphatically tracked and analyzed, all of which were correctly diagnosed and effectively prevented.
There is obvious precipitation of underground reuse water in fully mechanized mining face of Halagou Mine (1)222 16, which leads to serious blockage of pilot filter element of hydraulic support. Through ferrography analysis of water quality, determination of antirust performance and analysis of mechanical impurities, combined with the water quality test report, it is concluded that iron ions in water source contact with air in the pipeline in the process of following the water flow, forming water-insoluble iron oxide hydrate, which is the main reason for the filter plug.
(2) Since July 20th, the planetary head of the left rocker arm of the shearer in __205 fully mechanized mining face in Shangwan Mine has been abnormal continuously and has been seriously worn. After shortening the sampling period, the trend chart of 1 1 time was drawn continuously. Combined with the observation results of industrial endoscope, the following conclusions were drawn: the degree of wear gradually increased, mainly manifested in the increase of the particle size of fatigue abrasive particles and layered abrasive particles, with the average particle size at __0? M, indicating that all parts of the gearbox are seriously worn, which affects the normal operation. It is recommended to disassemble, inspect and replace it. After disassembly and inspection, it was found that there was contact friction and wear between the primary flange and the bearing outer ring, and the bearing outer ring was damaged as long as 1 m.

7, laboratory technical standards
The detection laboratory identified the ferrography analysis case of belt conveyor roller shaft in Shendong mining area and the application effect of ultrasonic flaw detection. According to national standards and industry standards, the statistical test data are analyzed and the evaluation conclusions are constantly improved. After a year of data accumulation, the Technical Standard for Ferrography Analysis of Coal Mine Equipment Oil and the Technical Standard for Ultrasonic Inspection of Belt Conveyor Roller Shaft have been compiled and reviewed by the expert group organized by Shenhua Group.
The four patented technologies involved in these two standards have been declared by the Science and Technology Development Department of the Group Company to the State Patent and Technology Bureau. They are: belt conveyor roller shaft full-axis penetration flaw detection method, belt conveyor roller shaft bearing seat embedded parts flaw detection method, belt conveyor roller shaft journal or unloading groove part flaw detection method, and equipment quality control method using rotary ferrography.
8, belt conveyor roller shaft flaw detection
From _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Since the beginning of flaw detection, there has not been a broken shaft of belt conveyor in the whole company.
The company 14 mines have all installed ultrasonic flaw detectors. Twenty-six technicians from various mines, washing, distribution, maintenance centers and equipment management centers of the company have understood the ultrasonic flaw detection training, and 24 have obtained the second-class flaw detection qualification certificate.
9, personnel training forensics scene
In 20__ years, the testing laboratory * * * completed 32 trainings, and * * * organized 84 person-times to participate, including 24 self-training and 8 outsourcing trainings, and ***22 person-times obtained relevant business qualification certificates.
According to the technical weakness of the recruits, the corresponding training plan is formulated in three stages.
(1) Point-to-face training: Expatriate personnel to study first, then promote the whole staff to learn through the second lecture, and enhance the training effect in the form of mentoring.
(2) Business cross-training: assign each person to master 1 to 2 instruments and give lectures to all employees, mainly taking morning training.
(3) Mechanical and electrical testing business manual and typical case writing: mechanical and electrical business mobile phone writing and theory with practice training. Through the continuous tracking of motors, reducers and other equipment, find out the law of equipment failure, and write a case to prevent equipment failure for all employees to learn.
Second, the existing problems
1, the level of equipment fault diagnosis can't meet the development needs of Shendong: at present, the instruments and means of equipment fault diagnosis basically meet the needs of daily work, but the technical skills of personnel analysis can't meet the requirements, so they can only collect data and simply analyze data, and can't determine the root cause of the fault.
The first reason is that the basic quality of personnel's business is poor and they need professional training;
The second reason: there are few diagnostic doctors and many businesses, and there is not enough time to study and analyze data, resulting in less experience.
2. The procurement cycle of chemicals, tools and accessories is long: due to the particularity of testing laboratory equipment, the material supply center has no corresponding spare parts; The reported planned procurement progress of materials is slow, which seriously affects the normal development of testing work.
3. Incomplete acceptance items of newly arrived materials: At present, the laboratory can only accept 17 products of three kinds of materials, which is far from meeting Shendong's arrival acceptance requirements. The annual arrival of spare parts in the material supply center is about 5 billion yuan, but at present, it can only accept less than _ _ _ billion yuan. It is necessary to continuously expand testing items, improve testing skills, and completely prevent unqualified products from entering Shendong from the source.
4. Laborers become an unstable factor in testing: At present, there are 27 workers in the testing laboratory, of whom _ _ is a laborer. Due to factors such as low wages, unstable workers' thinking and high mobility, the level of testing and inspection has not been steadily improved.
5. The professional quality of the personnel is low, so it is necessary to strengthen the professional knowledge training: the specialty of the testing laboratory personnel is quite different from the business they are engaged in, and the knowledge structure is difficult to transform, so it is necessary to strengthen the professional skills training.
