Do you need a filter for the return air of a biosafety level 2 laboratory?

Domestic standards are not required (if your air conditioner is made in China is very much needed), foreign is a must.

Level II biosafety cabinet is 100% exhausted.

Bio-clean safety cabinets are essential in today's microbiology labs, especially where protective measures are required for the operator. For example, medical, pharmaceutical, scientific research, etc. provide a sterile, dust-free and safe working environment when bacterial culture.

Level II Biological Safety Cabinet Features:

1. 100% discharge of constant airflow, negative pressure vertical laminar flow.

2. Move the glass door up and down, which can be positioned arbitrarily, easy to operate, and can be completely closed for sterilization, and the positioning height limit alarm prompts.

3 Work area power output outlet.

4 HEPA filters are suitable for filtering particulates, smoke and microorganisms in the air. Two layers are filtered into the above HEPA membrane.

5. The working environment is made of high-quality 304 stainless steel, which is smooth, seamless, and has no dead angles, which can be easily and thoroughly disinfected, and can prevent the erosion of corrosives and disinfectants.

6 Controlled by LED LCD panel.

7. Equipped with high-efficiency filter failure alarm function.

8. Airflow outflow alarm in the work area.

A2 is 30% external exhaust air, 70% internal recycling, B2 is 100% external exhaust air, B2 must be equipped with an external exhaust fan, auxiliary air duct exhaust use.

During the epidemic, nucleic acid testing is used to determine whether the virus is infected, but the whole process must be tested in the biosafety laboratory, so how the laboratory level is divided into service and training suspicions, how the virus is transmitted, and what are the requirements for the construction of biological laboratories.

The following requirements should also be met for a Level 2 biosafety laboratory:

1) The door at the entrance of the laboratory and the door to the laboratory room where the biological safety cabinet is placed should be automatically closed; The entrance door to the laboratory should have access control measures.

2) There should be conditions for storing spare items outside the laboratory work area.

3) The laboratory work area should be equipped with an eyewash device.

4) The laboratory or its building should be equipped with an autoclave or other appropriate disinfection and sterilization equipment, and the disinfection and sterilization equipment should be based on a risk assessment.

You can consult the Science and Education Department of the Health Department of the province, and they will tell you how to do it.

The main processes are: 1 unit information filing, 2 system document filing, 3 laboratory filing, 4 pathogenic microorganisms filing.

Generally, it is to register the unit enterprise online for the management information of the pathogenic microbiology laboratory, and upload the basic information of the unit and enterprise.

The Municipal Health Bureau will approve it online, but there are some steps to send paper materials to the Health Bureau. Units and enterprises should participate in the training course on biosafety technology and management of the second-level biosafety laboratory held by the Health Bureau and the Center for Disease Control and Prevention, obtain the laboratory biosafety post training certificate (at least 3 people in each laboratory), and establish a biosafety committee and appoint a chairman. The paper materials mentioned above must be signed by the chairman of the unit's biosafety committee.

The procedures for filing with Level 2 biosafety laboratories are as follows:

1.The health administrative department of the county (district) where the laboratory is located shall organize relevant departments to conduct a preliminary examination, and report to the Municipal Health Commission for the record after passing the preliminary examination.

2.The following materials need to be submitted for ICP filing:

The basic information of the laboratory, including the name of the laboratory, the level of the laboratory, the person in charge of the laboratory, etc.

The safety management system of the laboratory, including the safety responsibility system, the laboratory biosafety operation procedures, the laboratory waste disposal system, etc.

Protective measures in the laboratory, including the safety of laboratory equipment, protective measures for laboratory personnel, etc.

Other circumstances that need to be explained.

The specific regulations may vary from region to region, so it is recommended to consult with the relevant authorities.
