The so-called P2 laboratory is simply a type of laboratory in a biosafety laboratory that reaches the P2 level, and its experimental subjects are microorganisms with moderate potential harm to humans and the environment.

P2实验室装修有6条注意事项，分别是技术指标的确定、建筑结构与装修要求、空调通风和净化、应配备的工艺设备、实验室电气设置、排水与消防要求。

There are 6 precautions for P2 laboratory decoration, including the determination of technical indicators, building structure and decoration requirements, air conditioning ventilation and purification, required process equipment, laboratory electrical settings, drainage and fire protection requirements.

1.技术指标的确定：技术指标必须符合《生物安全实验室建筑技术规范》，具体来说为洁净度无要求;与室外方向相邻相通房间的压差无要求;小换气次数为可开窗通风;温度为18-27℃;相对湿度为30-70%;噪声≤60dB(A);低照度为300lx。进行P2实验室装修，必须满足这些低指标。

1. Determination of technical indicators: The technical indicators must comply with the "Technical Specifications for Building Biosafety Laboratories", specifically, there are no requirements for cleanliness; There is no requirement for the pressure difference between adjacent and connected rooms in the outdoor direction; Small air changes can be done by opening windows for ventilation; The temperature is 18-27 ℃; The relative humidity is 30-70%; Noise ≤ 60dB (A); The low illumination is 300lx. To carry out P2 laboratory decoration, these low indicators must be met.

2.建筑结构与装修要：P2实验室的房门应具备自动关闭功能，如果实验室面积较大，且预算充足，可以设立缓冲区域。为了确保室内的温湿度指标，必须设立机械通风系统。此外，还要有预防昆虫、鼠等昆虫与动物进入和外逃的措施。

2. Architectural structure and decoration requirements: The door of P2 laboratory should have automatic closing function. If the laboratory area is large and the budget is sufficient, a buffer area can be set up. In order to ensure the indoor temperature and humidity indicators, it is necessary to establish a mechanical ventilation system. In addition, measures should be taken to prevent insects, mice, and other insects from entering and escaping from animals.

3.空调通风和净化：P2实验室应设立带有循环风的空调系统，若实验对象或实验项目涉及到动物、感染性材料、化学溶媒等，那么必须设立全排风系统。生物安全柜要与排风系统连接，仪器的位置也要利于空气流通。

3. Air conditioning, ventilation, and purification: P2 laboratory should establish an air conditioning system with circulating air. If the experimental object or project involves animals, infectious materials, chemical solvents, etc., a full exhaust system must be established. The biosafety cabinet should be connected to the exhaust system, and the location of the instruments should also facilitate air circulation.

4.应配备的工艺设备：生物安全柜，主要分为Ⅰ级(适用于产生微生物气溶胶或出现溅出的操作)、Ⅱ级(适用于处理感性材料)、Ⅱ-B级(适用于处理化学致癌剂与放射性物质及挥发性溶媒)。其次是高温高压灭菌消毒柜、洗眼器、应急喷淋装置、超净工作台等。

4. Process equipment to be equipped: Biosafety cabinets, mainly divided into Class I (suitable for producing microbial aerosols or splashing operations), Class II (suitable for handling sensitive materials), and Class II-B (suitable for handling chemical carcinogens, radioactive substances, and volatile solvents). Secondly, there are high-temperature and high-pressure sterilization cabinets, eye washers, emergency sprinkler devices, and ultra clean workbenches.

5.实验室电气设置：是专用配电箱，且电源要设立漏电检测报警装置。其次是接电系统，注意接地电阻不能大于1Ω。后还要有显示工作状态的灯光讯号显示牌与紧急发光疏散指示标志。

5. Laboratory electrical setup: It is a dedicated distribution box, and the power supply should be equipped with a leakage detection and alarm device. Secondly, the grounding system should be connected, and the grounding resistance should not exceed 1 Ω. Afterwards, there should also be a light signal display board displaying the working status and an emergency illuminated evacuation indicator sign.

6.排水与消防要求：对于P2实验室装修而言，排水与消防要求也很重要。先来看排水，实验室内要设立高温高压消毒或化学消毒设备。再来看消防，实验室的建筑物耐火等级不能低于二级。

6. Drainage and fire protection requirements: For P2 laboratory decoration, drainage and fire protection requirements are also important. Let's first take a look at drainage. High temperature and high pressure disinfection or chemical disinfection equipment should be installed in the laboratory. Looking at fire protection, the fire resistance rating of laboratory buildings cannot be lower than Level 2.
