Planning and DesignPlanning and design
Public security system laboratories are mainly used for auxiliary investigations in criminal investigations, mainly drug test laboratories, DNA identification laboratories and PCR clean laboratories. Common public security bureau (criminal investigation) laboratories mainly include professional laboratories for physical, chemical, poisoning, forensic material evidence, DNA, trace inspection, document inspection, and imaging technology analysis.

I. Acceptance Standards of Public Security Laboratory
The decoration planning of the public security system laboratory mainly refers to the following standards:
(1) Basic acceptance criteria:
① The Ministry of Public Security's "Public Security Criminal Science and Technology Equipment Standards" is the minimum standard
② The Ministry of Public Security's "Civil Science and Technology Business Construction Standards for County and City Public Security Organs" is the basic standard
(B) grade evaluation standards:
① "Code for the Construction of Forensic Science DNA Laboratory"
② "Methods for Grade Evaluation of Public Security Criminal Science and Technology Office"
③ "Technical Specifications for the Construction of Biosafety Laboratories" GB50346
④ "General requirements for laboratory biosafety" GB19489
⑤ "Code for Construction and Acceptance of Ventilation and Air Conditioning Engineering" GB50243
⑥ "Microbiological and Biomedical Laboratory Biosafety Application Guidelines" WS233
⑦ "Specifications for Construction and Acceptance of Clean Room" JGJ71

2. Planning Standards for Public Security System Labs
(1) DNA Lab of the Public Security Bureau
The DNA laboratory of the Public Security Bureau mainly conducts genetic identification and individual identification and work:
① The DNA laboratory is divided into four relatively independent areas: the DNA extraction area, the PCR amplification area, the detection area, and the test material preservation experiment data analysis and processing area, which are constructed in accordance with international and domestic Ministry of Public Security standards.
② Strictly speaking, the entire area of the DNA laboratory of the Public Security Bureau needs cleanliness requirements, generally around 100,000 to 10,000.
③ At present, most units do not have this concept during construction. They only use colored steel plates as partitions, but only make clean areas.
④ The PVC laboratory floor of the Public Security Bureau is better for PVC. It is relatively durable, and the colors are also selected. It is easy to replace even if it is aging. Some units also use epoxy self-leveling floor, but it is not recommended, the floor is not abrasion-resistant, and it is not easy to maintain and update.
(II) Laboratory of the Forensic Inspection and Identification Center of the Public Security Bureau
① The laboratory of the Forensic Inspection and Appraisal Center of the Public Security Bureau is responsible for the task of forensic science. It is a special science and technology industry, and its conclusions will provide arguments for the courts, which are related to the protection of citizens' rights and justice.
② The physical evidence appraisal business of the laboratory of the Forensic Inspection and Appraisal Center of the Public Security Bureau generally includes: forensic pathological damage, DNA, poisoning, forensic physical evidence, traces, criminal photography, fingerprints, trace physical evidence, documents, bullets, explosions and other inspection and identification work.
Third, the public security system laboratory configuration
Basic requirements for the layout of the laboratory:
1. Between safety devices: The aisle spacing between safety devices is> 6 feet.
2. Experimental bench and safety equipment: the aisle distance is 6 feet, about 1800mm;
3. Work space for one person and one side: the distance between the walkways is 4 feet, about 1200mm; the height of the objects is 5 feet, about 1500mm; the operating clearance is 2.5 feet, about 750mm;
4. Double-sided double-sided working space: the aisle distance is 5 feet, about 1500mm; the height of the objects is 5 feet, about 1500mm; the operating clearance is 2.5 feet, about 750mm;
Fourth, the basic requirements of the public security system laboratory:
(I) Laboratory lighting:
① In general, the physical and chemical laboratory should face southeast to facilitate daylighting;
② The instrument should face northwest to facilitate constant temperature and humidity control;
(Two) laboratory hydropower:
① A reasonable laboratory hydropower layout system is an important basis for laboratory planning and design;
② The piping methods of the laboratory such as electricity, water, and gas are very important in the laboratory design. It must be based on the laboratory content and building form (high-rise or bungalow), laboratory functions, safety requirements, funding requirements, and future expansion requirements And so on for a comprehensive consideration.
(Three) laboratory air conditioning:
① A reasonable amount of air supply and exhaust rate are important to the health of laboratory staff and the accuracy of experimental data;
②Exhaust rate: physical laboratory (3-8 times / hour), biological laboratory (5-30 times / hour), chemical laboratory (6-20 times / hour), organic synthesis laboratory (15-18 times / hour) Hours), toxic laboratory (20-30 times / hour), R1 laboratory (15-30 times / hour), medical laboratory (5-10 times / hour)
(IV) Dimensional requirements of laboratory corridors, doors and windows:
① Corridor width should be> 5 feet
② Door frame size (width * height): 3 feet * 7 feet (domestic 900mm * 2000mm);
