Explore the design of the CDC laboratory
1. Main basis for the construction of disease control laboratory
The laboratory of the CDC should be prepared for the feasibility study report and design requirements, whether it is reconstruction or new construction. In the feasibility study report and design requirements, the main basis of laboratory construction must be listed to meet the national construction of the laboratory. Related requirements, and this work is generally proposed by the CDC professionals.
The main basis is:
Guiding Opinions on Laboratory Construction of Provincial, Prefecture and County Centers for Disease Control and Prevention, Ministry of Health, National Development and Reform Commission [2004] No. 108
"Building Standards for Disease Prevention and Control Center" Ministry of Housing and Urban-Rural Development, National Development and Reform Commission, Ministry of Health, 127-2009
"Technical Specifications for the Construction of Biosafety Laboratories" GB50346-2011
General Requirements for Laboratory Biosafety GB19489-2008
General Guidelines for Safety of Microbiology and Biomedical Laboratories WS233-2002
"Scientific Experimental Building Design Code" JGJ91-93
Approval of the Regulations on the Safety Management of Dangerous Chemicals by the State Council 2011.3.2
Approval of the Medical Waste Management Regulations by the State Council in 2003.6.4
Cleanroom Construction and Acceptance Specifications GB50591-2010
National AIDS Testing Technical Specification, 2009 Edition
"Basic Requirements for Specialized Laboratories, Tuberculosis, and Vectors"
Requirements for the "Measurement Law, Certification and Accreditation Regulations, Laboratory and Inspection Agency Qualification Certification"
National standards such as "earthquake, lightning protection, fire protection".
2. The construction and planning of the disease control laboratory should follow the principle
2.1 Scientific and reasonable principles, reasonable site selection, standard process layout, smooth logistics and logistics organization, and advanced design concepts.
2.2 The principle of safety first position, meet various biosafety requirements, set necessary safety measures to ensure the safety of laboratory personnel and the environment, and all construction and planning are subject to biosafety.
2.3 The principle of professional layout, biosafety risk assessment, scientific, reasonable, overall conception and conceptual design, meet the operating procedures for process layout design, and then design ventilation, air conditioning, electrical, water supply and drainage, fire protection, bio-safety measures.
2.4 The principle of complete functions, combined with the function of the local laboratory to set up the laboratory, meet the requirements of disease prevention and detection in this area.
2.5 The principle of long-term planning, advanced awareness, high standards, strict requirements, leaving room for development in space.
2.6 Easy to use, easy to control, easy to manage, easy to operate.
2.7 People-oriented principle, embody the concept of humanization and human care, and create a comfortable testing environment.
2.8 The principle of strict economy, according to the workload of the test project, economic situation, combined with its own actual situation, under the premise of meeting biosafety, save.
3. General requirements
3.1 Reasonable site selection and clear functional division
The location should be away from residential areas and public buildings, and should be on the downwind side of the bustling area of ​​the city.
3.2 Functional partition principle
3.2.1 Divide the functional area horizontally or vertically.
3.2.2 The laboratory area should be isolated from the office area.
3.2.3 Laboratories with high toxicity and high infectivity should be isolated from the common laboratory area and become relatively independent or independent areas.
3.2.4 Laboratory flow should be excessive from safe and low-toxicity laboratories to highly highly infectious laboratories. Highly infective laboratories should be kept away from the frequent active areas of the personnel and placed as far as possible at the end of the corridor.
3.2.5 The laboratory area should be placed as far as possible between the two evacuation stairs.
3.2.6 Each laboratory shall be reasonably divided according to the relevant management specifications, operating procedures and operating procedures of the laboratory.
3.3 Logistics, sewage logistics, air flow organization principles
Logistics: from sample sample area → → laboratory auxiliary area → → general laboratory area → → low toxicity laboratory area → → highly highly infectious laboratory area, controlled area.
Sewage logistics: disinfected and packaged by highly highly infective laboratory areas, controlled areas, or low-toxic laboratory areas → → dirt channels → → dirt stairs or elevators.
Air flow: from the cleaning area → → semi-polluted area → → contaminated area, controlled area, negative pressure.
From the area with high cleanliness→→the area with low cleanliness→the area of ​​non-clean area, positive pressure.
4, laboratory process design points and recommendations
4.1 Master plan
The civil works and the laboratory are built separately, and the laboratory should be subcontracted, designed separately, tendered and constructed.
A floating shelf is a form of shelf with its wall fixings hidden within the shelf board, with no visible supporting brackets. It can be supported on hidden rods or bars that have been attached to studs. A thick floating shelf may be made of a hollow-core shelf glued to a cleat.
A floating shelf may have two or more channels open from the back towards, but without reaching, the front, into which slide fasteners attached to the wall, typically held in place by screws inserted through the bottom of the shelf.
For typical floating shelf supports, a supplier suggests that floating brackets with a diameter of 12mm can support a shelf at least 22mm thick loaded with 20kg, and 18mm brackets can support 30kg on a 28mm shelf.
This description is in reference to one particular type of floating shelf support, others options are available. Also not to be confused with corner shelves, which would require entirely different supports to make them "float".
Floating shelves are a good fit for a contemporary minimalist style interior.They can be used to expand storage space, atop a radiator to double as storage, or inside a hallway to double as a console table.
