1. For multiple level 3 main laboratories, a public isolation corridor should be set up in front of each buffer room.Mobile container biosafety laboratory.
2. Adjacent rooms need to be provided with a pass-through window, the two doors are interlocked, and an effective disinfection device is provided.
3. The surface coating is antistatic.
4. No external windows should be provided for level 3 and above, but closed observation windows can be provided on the inner wall; the laboratory room door can be automatically closed, the room door should be equipped with a window, and the buffer room can be locked in one direction.
5. In semi-contaminated areas, no manholes or inspection ports shall be installed on the ceiling of the contaminated area.
3. General Requirements for Air Conditioning and Ventilation
The fresh air system should be adopted, and the air supply and exhaust main pipes should be airtight valves; the contaminated area should be close to the air-conditioning machine room.
Fourth, the air supply system
The elementary, middle, and high-efficiency filter should be installed. The high-efficiency filter should be installed at the end of the system, and the new air outlet should be 2.5m above the outdoor ground.
Five. Exhaust system
1. Mobile container biosafety laboratory. The exhaust air and the supply air are interlocked, the exhaust air is turned on before the supply air, and then closed with the supply air;
2. Indoor exhaust vents must be provided, and biological safety cabinets must not be used for exhaust; room exhaust ducts can also be used as biosafety cabinet exhaust ducts, and the negative pressure and exhaust requirements of the safety cabinet must be guaranteed.
3. The exhaust air needs to be filtered by a high-efficiency filter before being discharged; the high-efficiency filter should be installed at the indoor exhaust outlet and close to the exhaust outlet, and a level 3 laboratory can be equipped with 2 high-efficiency filters.
4. The positive pressure section of the exhaust duct should not pass through the room. The 3-4 laboratory should be equipped with a spare exhaust fan unit and switch automatically;
5. Level 3-4 laboratories should have measures to adjust the exhaust air to maintain the stability of the indoor pressure and differential pressure gradient; the outdoor air exhaust position should be 2m higher than the roof.
