Detailed Explanation of Acceptance Standards and Procedures for Animal Laboratory Projects
创建于04.09
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.
