With the continuous development of science and technology in our country, higher requirements are placed on the level of laboratory testing and R&D. In order to meet the needs of detection and scientific research, we must improve the level of laboratory design and construction. Therefore, this article studies the establishment of a standard system for the design and construction of laboratories, which is undoubtedly of theoretical significance for promoting stable and sustainable development of laboratories.
The status of laboratory design and construction standards
The laboratory height is 2.6 to 3 meters. Each function will be divided according to its irreversible process flow, actual use, equipment placement, humanization, and other factors; function divisions are:
Ordinary experimental area—forensic physical evidence routine testing room, forensic physical evidence storage room, case receiving room, sample testing room, bone extraction laboratory, data comparison analysis room, emergency shower room, sanitary ware room, laundry room, sequencer special UPS Engine room
Special experimental area/pollution control area—more shoes/buffer corridors, changing/buffering rooms, on-site physical DNA extraction room (30-50m2), suspect blood sample DNA extraction room (15-30m2), reagent mix room (15 -30m2), between PCR amplification (15-30m2), sequencing of amplified products (15-30m2);
The basic pattern of the pollution control zone Program 1, the various functions collusion, that is, the use of suites for the flow of people / logistics, this case should be strictly prohibited, first from the room layout to avoid cross-contamination;
Problems in laboratory design and construction system
(I) Different laboratory design concepts
At present, in the design and construction of developed countries, more emphasis is placed on environmental protection, energy conservation, safety, comfort, and sustainable development. In China, due to the late start of modern design and construction, most managers did not realize the importance of laboratory energy conservation, environmental protection and sustainable development. It is undeniable that comfort, environmental protection, energy saving and safety not only directly affect the work of laboratory personnel, but also have a huge impact on the natural environment. For example, the laboratory will produce a certain experimental waste liquid after the experiment process or experiment is completed. If it is discharged into the natural environment without being treated, it will cause great harm to the natural environment, and even affect the human body's health. From this, it can be seen that the establishment of standards for the design and construction of laboratories is more conducive to the stable and sustainable development of laboratories.
(B) lack of standards for laboratory design and construction
Compared with foreign countries, the design and construction of laboratories in our country have different standards, technologies, and materials used in the industry, and the design and construction levels are also very different. The technical level of many laboratory designers and constructors cannot meet the needs of modern experimental design and construction. For example, in the design and construction of laboratory fume hoods, fume hoods are the basic equipment for ensuring the normal operation of laboratory equipment and personnel safety. However, in the actual design and construction process, some designers and designers pay too much attention to the operating status of the equipment and ignore the experiment. Room staff safety design. And, it is not aware of the importance of laboratory-based fume hoods for energy conservation and environmental protection.
(A) follow the concept of laboratory design
In the design process of the experiment, a unified design concept should be established. First of all, we should attach great importance to the safety of laboratory design, such as ensuring the four basic criteria for experimental design: (1) ensure the safe storage of hazardous materials; (2) strictly protect the security of intellectual property; (3) the laboratory should design rooms and Controlled access control systems; (4) Important rooms in the laboratory are not allowed without permission and are accessible to anyone in the public area. Second, focus on the design of sustainable laboratory development. For example: designing waste gas and wastewater treatment systems to reduce the emission of hazardous wastes; establishing laboratory waste liquid recovery and utilization systems; designing intelligent control systems to increase the efficiency of the use of laboratory water resources and electricity, and achieving laboratory energy conservation and environmental protection; The complementary products in the laboratory should use recyclable materials. Finally, improve the comfort of the laboratory design. In order to realize the needs of modernization and sustainable development of laboratories, the laboratory should be designed to be more comfortable and comfortable, create a comfortable public environment for laboratory workers, and ensure the stability of the laboratory, the development of Keycon, and sustainable development. .
(B) Strengthening the establishment of laboratory design and construction standards
At this stage, various standards have reached more than 2,000, involving 15 laboratory management projects, 23 laboratory safety projects, and more than 10 design standards for different departments, including aquatic animal quarantine inspection laboratories and biosafety laboratories. Room, measurement laboratory, mechanical industrial central laboratory, science laboratory, etc. From this we can see that the standards for laboratory design and construction are more stringent and extensive. In the process of laboratory design and construction, it is important to establish a unified standard system. For example: In the laboratory | DNA sequencing process, from the sample sampling to the sequencing room experiments, strictly follow the rules of each process of the experiment to ensure the purity of the sample and the integrity of the data. In addition, during the design of the laboratory space, it is necessary to ensure a comfortable space for the laboratory staff. In the daylighting design, natural light should be used as much as possible, and the HVAC system should be properly designed so as to meet the needs of laboratory personnel.
In summary, this article analyzes the current situation of laboratory design and construction standards, and addresses the problems in the laboratory design and construction system, and proposes two measures to strengthen the establishment of laboratory design standards and follow the concept of laboratory design. However, the lack of standards for laboratory design and construction and different laboratory design concepts still affect the quality of design and construction. Therefore, in the future work, it is necessary to strengthen the research on the establishment of the laboratory design and construction system, and make greater contributions to improving the level of laboratory design and construction and promoting stable and sustainable development of the laboratory.
