Engineering of Animal Laboratories: Modular Space Planning Strategies Based on Experiment Types
In the field of animal experiments, scientific space planning is of utmost importance for the smooth progress of experiments, the accuracy of results, and the safety of both personnel and animals. Guangzhou Cleanroom Construction Co., Ltd., as a professional manufacturer of purification equipment, is well - aware of the unique space layout requirements of different animal experiments. Here, we introduce the modular space planning strategies based on experiment types.
I. Characteristics of Animal Experiment Types and Space Requirements
Basic Biological Research Experiments
These experiments involve animal breeding, reproduction, and the detection of basic physiological indicators. A large and reasonably - laid - out breeding area is required, equipped with environmental control systems for temperature, humidity, and lighting to ensure the healthy growth of animals.
At the same time, there should be an independent experimental operation area with good cleanliness and ventilation conditions to prevent cross - contamination.
Drug R & D Experiments
During drug R & D, it is necessary to administer drugs to animals, observe drug reactions, and conduct pharmacokinetic studies. A dedicated drug - administration operation room needs to be set up, equipped with precise drug - administration equipment and safety protection facilities.
An advanced analytical instrument room is also required, which should be isolated from other areas to avoid external interference with the detection results. In addition, due to the involvement of multiple drugs and different doses, it is necessary to reasonably plan the drug storage area.
Infectious Disease Research Experiments
Biosecurity is the top consideration in infectious disease research experiments. A strict biosecurity protection area must be set up, with negative - pressure ventilation to prevent the leakage of pathogens in the laboratory.
The experimental operation area is designed according to the biosecurity level, equipped with biosafety cabinets, autoclaves, and other equipment to handle experiments and waste. At the same time, an independent animal infection area is set up, completely isolated from other areas, and equipped with exclusive passages and transportation equipment.
II. Modular Space Planning Strategies
Functional Module Division
Animal Breeding Module: Divide the breeding area according to animal species and habits, such as rodent breeding area and non - human primate breeding area. Each module is equipped with independent ventilation, temperature control, humidity control, and automated feeding and watering devices. An observation passage is set up to facilitate daily observation.
Experimental Operation Module: According to the experimental process and functions, it is divided into laboratory modules such as sample collection, cell culture, and molecular biology. Each module adopts different purification and ventilation equipment according to the cleanliness requirements. For example, the cell culture room is equipped with a super - clean workbench and a CO₂ incubator to maintain a high level of cleanliness; the molecular biology laboratory sets up a special area and takes anti - static and other measures.
Equipment and Instrument Module: Concentrate experimental instruments and equipment, and layout them according to the type and frequency of use. Large - scale instruments are equipped with anti - vibration, dust - proof, moisture - proof facilities, and independent power supply and cooling systems; small - scale instruments are grouped according to functions, and a maintenance passage and space are set up.
Waste Treatment Module: Due to the biological hazards of waste generated in animal laboratories, a special module is set up, including a collection area (different containers are set up and labeled according to waste types), a temporary storage area (equipped with refrigeration and other conditions), and a treatment area (equipped with autoclaves and other equipment).
Connection and Coordination among Modules
Logistics Passage Planning: Plan a reasonable logistics passage to connect each functional module, ensuring that the passage size meets the transportation requirements. Different materials use different transportation routes to prevent cross - contamination.
Information Communication System: Set up information display screens and communication equipment in each functional module, allowing experimental personnel to understand experimental progress and other information in real - time. Use an information management system to uniformly manage experimental data and other information for easy query and sharing.
Emergency Response Mechanism: Each functional module formulates an emergency response plan to ensure the smooth flow of emergency passages and enable rapid isolation in case of emergencies. Equip emergency rescue equipment and materials to improve the emergency response ability of the laboratory.

In the field of animal experiments, the ultra-clean workbench is like a solid fortress safeguarding the accuracy and safety of experiments. It is not only a key equipment for maintaining a clean experimental environment but also an important line of defense to ensure reliable experimental results, the health of animals, and the safety of experimental personnel. Guangzhou Cleanroom Construction Co., Ltd., with its profound accumulation and professional advantages in the field of purification equipment manufacturing, tailor - makes engineering customization and performance optimization solutions for ultra - clean workbenches for animal experiments, helping scientific researchers break through numerous challenges and reach new heights in scientific research.
I. Stringent Requirements of Animal Experiments for Ultra - Clean Workbenches
Animal experiment scenarios are complex and diverse. Whether it is cell culture, microbiological research, or disease detection, extremely high requirements are placed on ultra - clean workbenches.
Take cell culture as an example. During the mammalian cell culture process, any slight microbial contamination may lead to abnormal cell growth or even death, thus causing the entire experiment to fail. When conducting animal disease detection, such as the detection of highly pathogenic viruses, if the cleanliness of the operating environment does not meet the standards, it will not only interfere with the accuracy of the detection results but also may lead to virus leakage, triggering serious public health and safety issues. Therefore, animal experiments require ultra - clean workbenches to have extreme cleanliness maintenance capabilities, good operational convenience, and reliable safety protection performance.
II. Guangzhou Cleanroom Construction Co., Ltd.: Ingenious Creation of Customized Ultra - Clean Workbenches
Personalized Design to Meet Diverse Needs
Guangzhou Cleanroom Construction Co., Ltd. deeply understands that different animal experiment projects have vastly different requirements for ultra - clean workbenches. For laboratories that need to frequently perform animal sample collection operations, we design the ultra - clean workbench with a large - sized operating surface and equipped with adjustable - height brackets, facilitating long - term comfortable operation for experimental personnel and improving work efficiency. For laboratories conducting animal disease detection, considering the potential infectivity of samples, we set up a negative - pressure isolation area inside the workbench to prevent cross - contamination between samples and the leakage of harmful microorganisms. At the same time, to meet the experimental space layout requirements, the ultra - clean workbench can be customized into various installation forms such as wall - mounted and floor - standing, flexibly adapting to various laboratory environments.
Selection of High - Quality Materials to Create Excellent Quality
In the selection of materials for ultra - clean workbenches, Guangzhou Cleanroom Construction Co., Ltd. never compromises. The cabinet is made of 1.5mm thick high - quality cold - rolled steel plates. After pickling, phosphating, and anti - corrosion treatment, the surface is electrostatically sprayed with epoxy resin powder, which not only has excellent acid - and alkali - resistance and rust - prevention performance but also effectively avoids particle shedding due to material aging, affecting the cleanliness of the experimental environment. The operating surface is made of all - stainless - steel material, ensuring firmness, durability, and easy cleaning and disinfection. As the core component of the ultra - clean workbench, we use ULPA ultra - high - efficiency filters, which can intercept particles of 0.12μm with an efficiency of up to 99.999%, providing an almost perfect clean air environment for experiments.
Innovative Structural Design to Enhance the Operating Experience
The ultra - clean workbench we designed fully takes into account the principles of ergonomics. It adopts a 10° inclined - angle operation interface design, allowing experimental personnel to easily access the entire workbench surface during operation and reducing the fatigue caused by long - term operation. The inclined front door and transparent glass door design greatly increases the field of vision of the operators, facilitating the observation of the experimental operation process. The setting of transparent tempered glass side windows on both sides not only improves the lighting performance, making the experimental environment brighter and more comfortable but also facilitates experimental personnel to observe the experiment from different angles. In addition, the design that the front cover can be directly opened facilitates the replacement of filters and electronic component accessories, reducing the difficulty and cost of equipment maintenance.
III. Performance Optimization: Doubling the Efficiency of Ultra - Clean Workbenches
Upgrade of the High - Efficiency Air Circulation System
The ultra - clean workbench of Guangzhou Cleanroom Construction Co., Ltd. is equipped with a direct - drive high - efficiency centrifugal fan. This fan has significant characteristics such as long service life, low noise, maintenance - free, small vibration, and stepless speed regulation. Its speed - regulation performance is stable, and its service life is up to 50,000 hours or more, which can continuously and stably provide strong wind power for the workbench. Through the optimization of the air duct design, a high - efficiency and uniform unidirectional air flow cycle is formed inside the workbench, quickly discharging pollutants in the working area and ensuring that the experimental environment is always in a high - cleanliness state. At the same time, this fan can be steplessly speed - regulated according to experimental needs. While meeting the wind speed requirements of different experiments, it can achieve energy - saving operation. Compared with traditional fans, under the initial resistance of the high - efficiency filter, it can save more than 50% of energy, greatly reducing the actual operating costs.
Empowerment of the Intelligent Monitoring and Early Warning System
To ensure the stable operation of the ultra - clean workbench and the safety of the experimental environment, we are equipped with an intelligent monitoring and early warning system. The workbench is equipped with a differential pressure gauge, which can clearly and real - time indicate the differential pressure changes on both sides of the high - efficiency filter. When the differential pressure reaches the set threshold, it will timely remind the staff to replace the high - efficiency filter to ensure that the filtration effect is always in the best state. In addition, filter pre - failure, damage, and blockage alarm technologies are also equipped. Once the filter has an abnormality, the system will immediately issue an alarm to avoid the experimental environment being polluted due to filter problems. The interlock design of the front window and the germicidal lamp further ensures the safety of experimental personnel. When the front window is lifted, the germicidal lamp automatically turns off to prevent ultraviolet rays from harming the experimental personnel.
Stringent Testing to Ensure Uncompromised Quality
Each ultra - clean workbench produced by Guangzhou Cleanroom Construction Co., Ltd. is strictly inspected one by one in accordance with the American Federal Standard 209E before leaving the factory.

BIM Technology: Empowering Animal Laboratory Engineering
In the current context of the continuous deepening of life science research, animal laboratories, as crucial research carriers, the quality and efficiency of their engineering construction have received increasing attention. Animal laboratory projects involve numerous complex systems, such as the precise control of the breeding environment for experimental animals, the strict aseptic guarantee in the experimental operation area, and the environmental protection requirements in the waste treatment area. The emergence of BIM (Building Information Modeling) technology has brought about a revolutionary change in animal laboratory engineering. As Guangzhou Cleanroom Construction Co., Ltd., which has been deeply engaged in the purification equipment field for many years, we have a profound understanding of the great potential of BIM technology in animal laboratory engineering and actively apply it to actual projects. Today, let's take you to understand how BIM technology reshapes animal laboratory engineering.
The Transformations Brought by BIM Technology to Animal Laboratory Engineering
1. Precise Design Visualization
Traditional design drawings of animal laboratories are often presented in two - dimensions, which are not intuitive enough for the display of spatial relationships and complex systems. BIM technology can construct a three - dimensional building information model, presenting various functional areas of the animal laboratory, such as the experimental animal breeding area, the experimental operation area, the personnel purification area, and the waste treatment area, in a vivid three - dimensional form. Designers can repeatedly adjust and optimize the layout of each area in the model, and experimental personnel can also visually experience the actual spatial effect of the laboratory after completion in advance, thus putting forward suggestions that are more in line with actual needs. For example, when designing the layout of the experimental operation area, through the BIM model, it can be clearly seen whether the placement of different experimental equipment is reasonable and whether there is enough space for personnel to operate, avoiding the problem of unreasonable space utilization being discovered only after construction.
2. Efficient Collaborative Design
Animal laboratory projects involve multiple professional fields such as architecture, structure, water supply and drainage, electricity, and purification. In the past, there were problems such as untimely information transfer and misunderstandings in communication and collaboration among different professions, which easily led to design conflicts. BIM technology provides a collaborative work platform, allowing designers from various professions to carry out design work on the same model. For example, when a water supply and drainage designer is laying pipeline routes, if there is a conflict with the electrical professional's lines, the BIM system will immediately issue a prompt. Through real - time communication and coordination, design conflicts can be quickly resolved, greatly shortening the design cycle and improving design quality. When participating in the design of animal laboratory projects, Guangzhou Cleanroom Construction Co., Ltd. closely collaborates with other professional teams with the help of BIM technology to ensure that the purification equipment we provide achieves the optimal in spatial layout and system integration.
3. Accurate Construction Simulation and Schedule Management
The uncertainties in the construction process are important factors affecting the progress of animal laboratory projects. BIM technology can simulate the construction process, discovering potential problems in the construction process in advance, such as unreasonable construction sequences and limited construction space. Through simulation, a more reasonable construction plan can be formulated, reducing errors and rework during the construction process. At the same time, BIM technology can also be used to track and manage the construction progress in real - time. By associating the construction schedule plan with the BIM model, by comparing the actual progress with the planned progress, schedule deviations can be promptly detected and corresponding measures can be taken for adjustment. For example, when installing purification equipment, through the BIM model, the installation sequence of the equipment and the required installation space can be clearly seen, ensuring the smooth progress of the construction process and improving construction efficiency.
4. Facility Management throughout the Life Cycle
The operation and management after the completion of the animal laboratory are equally important. The BIM model contains rich information about the laboratory's building structure, equipment, and facilities, and this information can provide strong support for facility management during the operation stage. Through BIM technology, managers can quickly query information such as the location, model, and maintenance records of equipment, facilitating timely equipment maintenance and upkeep. For example, when a purification device fails, through the BIM model, the location of the device can be quickly located, and detailed parameters and maintenance manuals of the device can be obtained, greatly shortening the maintenance time and ensuring the normal operation of the laboratory.
The Practice of Guangzhou Cleanroom Construction Co., Ltd. in the Application of BIM Technology
Guangzhou Cleanroom Construction Co., Ltd. actively applies BIM technology in animal laboratory projects to provide better services for customers. In the early stage of the project, we use BIM technology to jointly optimize the design plan of the purification system with the design team, ensuring the perfect integration of purification equipment with the overall layout of the laboratory. During the construction process, the installation of purification equipment is guided by the BIM model to improve installation accuracy and efficiency. At the same time, we also provide customers with facility management training based on BIM technology to help customers better operate and maintain the animal laboratory.
BIM technology is profoundly changing the construction and management mode of animal laboratory engineering. Guangzhou Cleanroom Construction Co., Ltd. will continue to give play to its professional advantages in the purification equipment field, combine with BIM technology, and create a more efficient, intelligent, and scientific - research - demand - compliant animal laboratory environment for customers. We look forward to working hand in hand with more scientific research institutions and enterprises to jointly promote the development of the life science research cause.

Guangzhou Cleanroom Construction Co., Ltd. has been deeply engaged in the purification equipment field for many years and has a profound understanding of the needs of animal laboratory projects. Today, we will analyze this key link in detail for you.
The Importance of Functional Zone Division in Animal Laboratories
An animal laboratory is not a simple combination of spaces but a complex system composed of multiple areas with specific functions. The rational division of functional zones can effectively avoid interference between different experimental activities, reduce the risk of cross - contamination, and also facilitate the operation and management of experimenters, improving work efficiency.
Analysis of Main Functional Zones
1. Experimental Animal Breeding Area
This is one of the core areas of an animal laboratory, where experimental animals live and grow. The breeding area needs to have good temperature and humidity control, ventilation, and lighting adjustment conditions to meet the physiological needs of experimental animals. The high - efficiency air purification equipment produced by Guangzhou Cleanroom Construction Co., Ltd. can provide a clean air environment for the breeding area, effectively filtering dust particles, microorganisms, and other pollutants in the air, reducing the risk of animals getting diseases and ensuring the health of experimental animals. For example, our [specific model] air purification unit adopts advanced filtration technology with a filtration efficiency as high as [X]%, which can accurately control the air quality in the breeding area.
2. Experimental Operation Area
Experimenters perform various experimental operations on experimental animals here, such as blood collection, dissection, and surgery. This area requires a strictly sterile environment to avoid contamination during the experiment and affect the experimental results. The clean benches of Cleanroom Construction provide a local high - cleanliness space for the experimental operation area. Its workbench surface is made of high - quality stainless steel, which is corrosion - resistant and easy to clean. The air flow in the work area is uniform and stable, which can effectively remove pollutants generated during the operation and ensure the accuracy and reliability of experimental operations.
3. Waste Treatment Area
Animal experiments generate a large amount of waste, including animal carcasses, experimental waste, and sewage. The rational setting of the waste treatment area is of great significance for environmental protection and biosafety. Guangzhou Cleanroom Construction Co., Ltd. provides professional waste treatment and purification equipment, which classifies and treats different types of waste. For example, our high - temperature sterilization equipment can harmlessly treat animal carcasses and experimental waste to ensure that the waste does not pollute the environment. At the same time, our sewage treatment equipment adopts advanced biological treatment technology, which can effectively remove harmful substances in the sewage and make it meet the discharge standards.
4. Personnel Purification Area
Before entering the experimental area, experimenters need to carry out purification operations such as changing clothes, washing hands, and disinfecting in this area to prevent experimenters from bringing external pollutants into the laboratory. The personnel purification passage designed by Cleanroom Construction is equipped with complete purification facilities, such as air showers, washbasins, and disinfection equipment. The air shower blows the personnel comprehensively with high - speed air flow to remove dust particles attached to clothes and the body surface, providing clean conditions for experimenters to enter the laboratory.
Principles and Methods of Rational Division
Principles
Function - proximity Principle: Areas with similar functions are divided together to facilitate experimental operation and management. For example, the experimental animal breeding area is set adjacent to the related feed storage area and cleaning tool storage area.
Pollution Control Principle: Strictly distinguish between clean areas and polluted areas to avoid cross - contamination. For example, the experimental operation area is set in a relatively clean area, while the waste treatment area is set in a location far from other functional areas and convenient for transporting waste.
Separation of Logistics and People Flow Principle: Reasonably plan the flow routes of experimental animals, experimental supplies, and personnel to avoid mutual interference. For example, set up special animal transportation passages and personnel passages to ensure the smooth progress of the experimental process.
Methods
Scientific Layout Planning: In the design stage of animal laboratory projects, fully consider factors such as the area requirements, spatial relationships, and equipment installation requirements of each functional zone, and draw a detailed layout plan. Guangzhou Cleanroom Construction Co., Ltd. has a professional technical team that can provide scientific and reasonable layout design plans according to the specific needs of customers and the actual situation of the laboratory.

Technical Points of Colored Steel Plate Installation on Walls in Animal Laboratories
In the construction of animal laboratories, the selection and installation of wall materials are of great significance. Colored steel plates, with their numerous advantages such as good heat insulation, fire resistance, moisture resistance, as well as being aesthetically pleasing and easy to clean, have become an ideal material for the walls of animal laboratories. As Guangzhou Cleanroom Construction Co., Ltd., which specializes in the production of purification equipment, we deeply understand the importance of colored steel plate installation technology in creating a high - quality animal laboratory environment. Today, we will introduce in detail the technical points of colored steel plate installation on walls in animal laboratories.
I. Preparation Work before Installation
(1) Material and Tool Preparation
Selection of Colored Steel Plates
According to the specific needs of the animal laboratory, select colored steel plates of appropriate specifications and quality. Generally, attention should be paid to the thickness of the colored steel plate, the quality of the coating, the type of core material, etc. For example, for areas with high requirements for environmental cleanliness, colored steel plates with rock wool as the core material can be selected. Rock wool has good fire - resistance, heat - preservation, and sound - insulation properties, and is not easy to breed bacteria. At the same time, ensure that the surface of the colored steel plate is flat, without scratches, deformation, or other defects.
Preparation of Auxiliary Materials
Prepare all kinds of auxiliary materials required for installation, such as sealants, self - tapping screws, angle irons, channel steels, etc. The sealant should have good weather resistance, water resistance, and sealing performance to ensure the sealing effect of the wall; the self - tapping screws should be selected in appropriate specifications according to the thickness of the colored steel plate to ensure firm fixation.
Tool Equipping
The installation tools include electric drills, screwdrivers, cutting machines, spirit levels, straightedges, etc. Ensure that the tools are in good condition and their accuracy meets the requirements. For example, spirit levels and straightedges are used to ensure the verticality and horizontality of wall installation.
(2) On - site Investigation and Planning
Measuring and Marking
Before installation, accurately measure and mark the installation position of the walls in the animal laboratory. Determine the axis position of the walls according to the design drawings, and draw ink lines on the ground and ceiling. Pay attention to error control during the measurement process to ensure that the positions of each wall are accurate, providing a benchmark for subsequent installation.
Wall Base Treatment
Check the condition of the wall base to ensure that the base is flat, firm, and dry. If there are uneven or loose phenomena in the base, leveling and reinforcement treatments are required. For example, for a concrete wall, if there are unevenness, it should be leveled with cement mortar; for an old wall, clean the dust, oil stains, and other impurities on the surface to ensure good adhesion between the colored steel plate and the base.
II. Technical Points during the Installation Process of Colored Steel Plates
(1) Installation of Keels
Selection and Processing of Keels
According to the size of the colored steel plate and the wall structure, select appropriate keel materials. Generally, light - steel keels are used. Process the keels, cut them into corresponding lengths according to the measured and marked positions, and carry out rust - removal and anti - corrosion treatments.
Installation and Fixation of Keels
First, install the vertical keels, fix them to the embedded parts or expansion bolts on the ground and ceiling to ensure that the keels are vertical. The spacing of vertical keels should be reasonably set according to the width of the colored steel plate, generally not exceeding 600mm. Then install the horizontal keels, and fix them to the vertical keels through connectors to form a stable keel framework. During the installation process, use a spirit level and a straightedge to check the verticality and horizontality of the keels at any time, and control the deviation within the allowable range.
(2) Installation of Colored Steel Plates
Cutting of Colored Steel Plates
Cut the colored steel plates accurately according to the size of the keel framework. Use a professional cutting machine when cutting to ensure that the cut is neat, smooth, and the size is accurate. Note to leave a certain installation margin to ensure that the colored steel plates are tightly spliced after installation.
Installation Sequence of Colored Steel Plates
Start from one end of the wall and install the colored steel plates one by one. Insert the colored steel plates into the keel framework, making the tongues of the colored steel plates interlock with the tongues of adjacent colored steel plates. Use self - tapping screws to fix the colored steel plates to the keels. The screw spacing is generally 200 - 300mm, evenly distributed around the colored steel plate. During the installation process, check the flatness and verticality of the colored steel plates at any time, and adjust them in time if there are deviations.
Treatment of Yin and Yang Corners
At the yin and yang corners of the wall, special yin and yang corner lines are required for treatment. Fix the yin and yang corner lines to the colored steel plates and keels to ensure that the yin and yang corner lines are straight, beautiful, and enhance the overall stability and sealing performance of the wall.
(3) Sealing Treatment
Sealing of Plate Joints
After the installation of colored steel plates is completed, seal the plate joints. First, use a sealant gun to evenly inject the sealant into the plate joints, fill them fully, and then use a scraper to scrape the sealant flat to make it flush with the surface of the colored steel plate. The sealant should be applied evenly, without missing coating, air bubbles, or other phenomena to ensure the sealing performance of the wall and prevent the entry of dust, microorganisms, etc.
Sealing of Penetrating Holes
For various penetrating holes on the wall, such as holes through which electrical conduits, water pipes, etc. pass, materials with good fire - resistance, water - resistance, and sealing performance should be used for blocking. First, fill the holes with fire - resistant putty, and then apply sealant on the surface to ensure that the holes are tightly sealed and do not affect the environmental control effect of the laboratory.
III. Inspection and Acceptance after Installation
(1) Appearance Inspection
Overall Flatness
Observe whether the colored steel plate wall is overall flat, without obvious unevenness. Use a straightedge to check the flatness of the wall, and the deviation should meet the relevant standard requirements, generally not exceeding 2mm.
Quality of Plate Joints
Check whether the plate joints of the colored steel plates are uniform and straight, whether the sealant is applied smoothly and without cracking or falling off. The width of the plate joints should be controlled within the design requirements, generally 3 - 5mm.
Effect of Yin and Yang Corners
Check whether the yin and yang corner lines are firmly installed, whether the lines are straight, and whether the angles of the yin and yang corners meet the requirements, generally 90°.
(2) Performance Testing
Sealing Performance Testing
Use methods such as smoke testing or pressure testing to test the sealing performance of the wall. Create a certain concentration of smoke inside the laboratory and observe whether there is smoke leakage outside the wall; or pressurize the inside of the laboratory and detect the pressure drop rate to determine whether the sealing effect of the wall meets the requirements.
Strength Testing
Check whether there are hollow sounds by tapping the colored steel plate wall to determine whether the connection between the colored steel plate and the keel is firm.

Detailed Explanation of Acceptance Standards and Procedures for Animal Laboratory Projects
In the field of scientific research, animal laboratories serve as crucial venues for various experiments. The engineering quality of these laboratories directly impacts the accuracy and reliability of experimental results. For Guangzhou Cleanroom Construction Co., Ltd., which specializes in the production of purification equipment and provides professional equipment support for animal laboratories, it is of great significance to have a deep understanding of the acceptance standards and procedures for animal laboratory projects. Today, let's explore this topic in detail.
I. Acceptance Standards for Animal Laboratory Projects
(1) Site Selection and Layout Standards
Environmental Site Selection
Animal laboratories should be far away from railways, docks, airports, traffic arteries, as well as factories, storage warehouses, and yards that emit a large amount of dust and harmful gases, to avoid severe air pollution, vibration, or noise interference. If it is impossible to be far away, they need to be arranged on the downwind side of the minimum frequency wind direction in summer in the local area. At the same time, the experimental animal experimental facilities should be kept at a distance of more than 50 meters from the living area to prevent mutual interference.
Internal Layout
A reasonable area division is the basis for ensuring the efficient operation of the laboratory. Generally, animal laboratories can be divided into the front area (including offices, maintenance rooms, warehouses, feed rooms, general corridors, etc.), the animal production area (such as quarantine rooms, buffer rooms, breeding rooms, etc.), the animal experimental area (buffer rooms, air shower rooms, quarantine rooms, etc.), and the auxiliary area (warehouses, washing and disinfection rooms, temporary storage rooms for waste items, etc.). Each area has a clear function, and through a reasonable passage design, the effective flow of personnel, animals, materials, and waste is realized to avoid cross - contamination.
(2) Building Hygiene Standards
Enclosure Structure Materials
The enclosure structure materials of the laboratory must be non - toxic and non - radioactive to ensure that they do not harm the health of experimental animals and laboratory personnel. The wall materials should be corrosion - resistant, not easy to fall off, impact - resistant, and non - reflective; the floor materials need to be non - slip, wear - resistant, and free of leakage for easy cleaning and maintenance; the ceiling materials should be water - resistant and corrosion - resistant to adapt to the special environmental requirements of the laboratory.
Requirements for Doors, Windows, and Corridors
The doors and windows of the building need to be well - sealed to prevent the entry of external pollutants. The width of the corridor should generally be ≥ 1.5m to facilitate the passage of personnel and equipment. For non - human primate animal laboratories, wire meshes should also be installed on the doors and windows of the breeding rooms to ensure the safety of animals.
(3) Facility and Equipment Standards
Ventilation and Air - Conditioning System
The ventilation and air - conditioning system is one of the key facilities in the animal laboratory. This system needs to maintain positive pressure operation, rationally organize the air flow, and scientifically arrange the positions of air supply and exhaust outlets to avoid air flow dead corners and cut - off phenomena. At the same time, it is necessary to ensure that various environmental control equipment is regularly maintained to stably maintain environmental indicators such as temperature, humidity, and air quality in the laboratory.
Electrical System
The power distribution equipment in the animal laboratory should be installed concealed, and equipment that is not easy to accumulate dust should be selected. An emergency power supply should be equipped to ensure the stability of power supply during the experiment. The electrical pipelines need to be laid concealed, and the pipe openings of the electrical pipelines entering the clean area from the non - clean area must be well - sealed to prevent dust and microorganisms from entering the clean area.
Animal Breeding and Experimental Equipment
Animal breeding cages, operating tables, experimental instruments, and other equipment should meet the corresponding experimental animal grade standards. For example, animal experiments with infectious diseases must be carried out under negative pressure conditions, and strict measures to prevent the leakage of harmful substances should be set up. Facilities above the barrier environment should also be equipped with detection instruments such as differential pressure gauges, and complete detection records should be kept.
II. Acceptance Procedures for Animal Laboratory Projects
(1) Application Stage
After the completion of the laboratory construction, the construction unit needs to submit an acceptance application to the relevant competent department. The application materials usually include detailed information on the laboratory construction project, such as design drawings, construction records, equipment lists, environmental test reports, etc., to prove that the laboratory has followed relevant standards and specifications during the construction process.
(2) On - site Inspection Stage
Formation of the Acceptance Expert Group
An acceptance group is formed by experts in the field of experimental animals, with no less than 3 members. The experts conduct a comprehensive inspection of the laboratory based on relevant standards and specifications.
Document Review
The acceptance experts first review the document materials submitted by the applicant unit to confirm whether the construction of the laboratory meets the design requirements, whether the construction process is standardized, and whether the various records are complete.
Field Inspection
The various areas of the laboratory are inspected on - site, including site selection and layout, building hygiene conditions, and the operation of facilities and equipment. Each key indicator of the laboratory is tested on - site, such as the wind speed, temperature and humidity of the ventilation and air - conditioning system, the safety of the electrical system, and the performance of animal breeding and experimental equipment.
(3) Result Evaluation Stage
Classification of Defect Items
During the inspection process, items that are incomplete, not comprehensive, or do not meet the standards will be identified as defect items. Among them, the failure of key items is called a serious defect, and the failure of general items is called a general defect.
Judgment of Acceptance Results
The acceptance results are judged based on the number and nature of the defect items. If there are no serious defects in key items and the number of general defects is within a certain proportion, the acceptance is passed, but the defect items need to be rectified; if there are serious defects or the number of general defects exceeds the specified proportion, a second acceptance may be required after rectification within a time limit.
(4) Rectification and Re - inspection Stage
Rectification Requirements
For the problems found during the acceptance process, the construction unit needs to complete the rectification work within the specified time according to the rectification opinions put forward by the experts and submit a rectification report.
Re - inspection and Acceptance
After the rectification is completed, the acceptance expert group will conduct a re - inspection of the rectification situation to confirm whether the rectification measures are effective and whether the laboratory has reached the acceptance standards. Only after passing the re - inspection and acceptance can the animal laboratory project be officially considered as passed the acceptance.
The acceptance standards and procedures for animal laboratory projects cover all aspects from site selection and layout to facilities and equipment, and from application to final acceptance. Guangzhou Cleanroom Construction Co., Ltd., with its professional purification equipment, provides a strong guarantee for the environmental control of animal laboratories, helps laboratories pass the acceptance smoothly, and lays a solid foundation for scientific research. Only by strictly following the acceptance standards and procedures can a high - quality, safe, and reliable animal laboratory be built to promote the steady progress of scientific research.
