Site selection requirements: The animal housing should be located in a quiet area away from the factory area that emits large amounts of dust, smoke, corrosive gases, and noise. If this cannot be avoided, it should be positioned on the downwind side of the prevailing wind direction in summer or on the upwind side of severe air pollution sources, maintaining a distance greater than 50m from living areas.

Layout requirements: The barrier environment of the animal housing laboratory emphasizes the separation of personnel flow, logistics, and animal flow, following a unidirectional route, with clean and dirty streams separated to achieve purification, sterilization, and pest prevention. Personnel must shower and change clothes before entering the clean corridor, which leads to the breeding room or laboratory, and then exit through the dirty corridor.

Environmental control parameters: The temperature should be controlled between 18~29℃ to meet the needs of different experimental animals. The pressure gradient within the system should be 20Pa to help maintain the cleanliness of the clean area. The air cleanliness should be at a hundred thousand level, ensuring that the air entering the laboratory is pure. Noise levels should be ≤50dB to provide a quiet environment for experimental animals.

Air purification system: An air conditioning system should be set up to ensure air cleanliness and control of temperature and humidity.

Floor layout: Set up clean corridors and dirty corridors to achieve a unidirectional flow of personnel, logistics, and animal flow, avoiding cross-contamination.

Other requirements: Provide drinking water and pure water to ensure the safety of drinking water for experimental animals. Use dust-free, moisture-proof, and anti-static epoxy resin flooring or PVC flooring, and set up cages, drinking water, and feed storage and distribution devices that meet the needs of the animals.

Building structure requirements: The materials used for the enclosure structure should be non-toxic and non-radioactive; it is recommended to use color steel plates produced by Baosteel, with core filling materials that meet national fire safety requirements for magnesium paper honeycomb color steel plates; the inner wall surfaces should be smooth and flat, with silicone sealing at the joints of the color steel plates; use rounded aluminum alloy corners at the junctions with the ceiling and floor; the ceiling should use 50mm thick magnesium paper honeycomb color steel plates; the floor should use imported brand homogeneous 2mm PVC sheets.

Building facility requirements: Doors and windows should have good sealing properties, using finished color steel doors, with observation windows on laboratory doors; the door opening width should not be less than 1000mm to facilitate the entry and exit of experimental items and equipment; the positions of the laboratory's air supply and exhaust should be reasonable, avoiding dead corners as much as possible; reasonably configure electrical loads based on the power consumption of each facility; all electrical wires should enter the facility's distribution box through the process interlayer; all wiring within the facility should be concealed, and the electrical control box should be clearly marked.

The above are the main standards that the animal housing needs to comply with. These standards aim to ensure the welfare of experimental animals, the accuracy of experimental results, and the safety of researchers.
