The so-called P2 laboratory is simply a kind of laboratory that reaches the P2 level in the biosafety laboratory, and its experimental objects are microorganisms with medium potential harm to humans and the environment. Below, I mainly introduce the precautions for P2 laboratory decoration.

6 precautions for P2 laboratory decoration

1. Determination of technical indicators: technical indicators must comply with the "Technical Specifications for Biosafety Laboratory Buildings", specifically, there is no requirement for cleanliness; there is no requirement for the pressure difference of the room adjacent to the outdoor direction; the minimum number of air changes can be opened Window ventilation; temperature is 18-27℃; relative humidity is 30-70%; noise is ≤60dB(A); minimum illumination is 300lx. For P2 laboratory decoration, these minimum indicators must be met.

2. Building structure and decoration requirements: The door of the P2 laboratory should have an 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, a mechanical ventilation system must be set up. In addition, there must be measures to prevent insects, rats and other insects and animals from entering and escaping.

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

4. Process equipment that should be equipped: First, the biological safety cabinet, which is mainly divided into level I (applicable to operations that produce microbial aerosols or splashes), level II (applicable to handling sensitive materials), and level II-B (applicable For the treatment of chemical carcinogens, radioactive substances and volatile solvents). Followed by high temperature and high pressure sterilization cabinets, eye wash, emergency spray device, ultra-clean workbench, etc.

5. Laboratory electrical settings: First, there is a dedicated distribution box, and the power supply must be equipped with a leakage detection and alarm device. The second is the power connection system. Note that the grounding resistance cannot be greater than 1Ω. Finally, there must be a light signal display board to show the working status and an emergency light-emitting evacuation sign.

6. Drainage and fire protection requirements: For P2 laboratory decoration, drainage and fire protection requirements are also very important. Let's look at drainage first. High temperature and high pressure disinfection or chemical disinfection equipment should be set up in the laboratory. Looking at fire protection again, the fire resistance rating of the laboratory building cannot be lower than Class II.

The above are the 6 precautions for the decoration of the P2 laboratory, please keep in mind.
