1, an overview of the
The laboratory should be far away from the noise, pollution sources and downwind of the factory. At the same time, there should be a green isolation zone, which can neither let the factory affect the laboratory environment nor let the animal laboratory pollute the factory environment.
2, animal laboratory purification equipment engineering including
P3 laboratory, office area and animal house are three large areas.
3. Positive and negative pressure barrier environment in immunodeficiency animal laboratory: negative pressure and positive pressure
Negative pressure: the workshop is smaller than the outside air, the indoor air does not expand to the outside. Positive pressure: the workshop is larger than the outside air, the outside does not expand the indoor.
Animal inspection and quarantine laboratory purification decoration
The basic requirements for the construction and interior decoration of the experimental animal house are as follows:
1, clean corridor to make clean corridor facilitate clean, disinfection, metope, ground and ceiling should be smooth, level off, without granular material peeling, metope and ground, ceiling and the connection of metope and metope should be made into arc shape.
In order to avoid damage to the wall when the cage frame is transported in the corridor, the skirting board of 20cm should be set at the foot of the wall. Corridor width need not be set too wide, in order to be able to pass the two largest cage frame trolley, but generally should not be less than 1.5m.
Walls can be painted with epoxy resin: the ground should be resistant to chemical corrosion, anti-slip, seamless, can choose epoxy resin or make it into a strong integrity of the terrazzo; The ceiling shall be moisture-proof, free from plastering and coated with epoxy resin paint.
Observation Windows shall be provided on the door leading to the feeding room in the corridor and shall be sealed. To prevent the animals from escaping, the door should close automatically. Skirting shall be provided for the lower part of the door on one side of the corridor.
Floor drain can be set in the clean corridor of common animal room. Special requirements of the animal room, the ground should not be set up drainage facilities.
2. The indoor wall, floor and ceiling of the feeding room shall be decorated the same as the clean corridor.
All indoor crevices, including the joints of walls, floors and ceilings, as well as the air pipes, electrical facilities and other equipment entering the room should be sealed around to prevent the inflow of unpurified air. No drainage facilities are provided indoors.
Wet mop can be used after cleaning.
In order to reduce the air conditioning load and adjust the light intensity as needed, there is no external window in the feeding room. Considering power failure and other factors, fixed sealing outer window can also be set. Clean workshop door is generally required to open inside.
3. The decoration in the pollution corridor is the same as that in the clean corridor.
The ground can be set drainage floor drain, when not sealed cover cover.
4. Other rooms in the laboratory animal room, in addition to the feeding room, there are also supporting rooms, such as the animal receiving room, the isolation room for quarantine observation, the cleaning and disinfection room for cages and utensils, the goods warehouse, laboratory, personnel purification room and office. The interior decoration of these rooms can refer to the treatment method of the corresponding room of the general biological clean room.
