Description of construction scheme of Meizhou P2 Laboratory

Meizhou P2 What are the contents of laboratory construction ？SICOLAB Xiaobian will explore the knowledge of laboratory construction with you in this article

One 、P2 laboratory The definition of

P2 The laboratory is a biosafety protection secondary laboratory , World health organization （WHO） According to the pathogenicity and the risk of infection, etc , Divide infectious microorganisms into 4 class ; According to equipment and technical conditions , Biological laboratories are also divided into 4 level （ Commonly referred to as P1、P2、P3、P4 laboratory ）,1 Lowest level ,4 Highest level . In all kinds of laboratories nowadays ,P2 The laboratory is the most widely used biosafety level laboratory .

Two 、P2 Basic configuration of laboratory construction

1、 The clean room shall be equipped with 2 A transfer window , Ensure the cleanliness of laboratory logistics . There is an ultraviolet lamp in the transfer window , The contaminated articles can be sterilized before being taken out of the laboratory , Ensure the isolation of outdoor and indoor air , indoor 、 The transfer window can be controlled outdoors , It reduces the number of laboratory personnel entering and leaving the laboratory , It is convenient for the experimenters to transfer their articles .

2、 The automatic door closer shall comply with the requirements of national specifications , An automatic door closer is installed on the door of the clean laboratory .

3、 A set of two door interlocking electronic interlocking is set in the laboratory of interlocking door , When one of the doors is open , The other door will not open , In this way, the airflow into the clean room is buffered , The airlock is also equipped with an emergency switch , When an accident occurs , Press the emergency switch to facilitate the laboratory personnel to escape from the site as soon as possible .

4、 The differential pressure gauge shall be in accordance with the biological laboratory specification , by P2 The laboratory is equipped with a set of differential pressure control system , Display indoor 、 External differential pressure , And the pressure difference can be manually controlled as required , Reach a safe range .

3、 ... and 、P2 Laboratory construction requirement

1、 The pressure difference between adjacent rooms connected to the outdoor direction ： No requirements

2、 temperature ℃：18~27

3、 Relative humidity %：30~70

4、 noise dB(A)：≤60

5、 Minimum illumination lx：300

Four 、P2 Laboratory decoration structure

The suspended ceiling and enclosure partition of the laboratory are made of polystyrene sandwich color steel plate , Thickness is 50mm, Steel plate is Baosteel 0.5mm,（ Color steel plate has the advantage of light weight 、 High mechanical strength 、 Good waterproof and thermal insulation performance ）; At the corner of the wall and between the wall and the ground 、 The included angle between the wall and the top plate adopts aluminum alloy arc internal and external transition and sealing , All matching aluminum alloy profiles are electrophoretic profiles , In order to prevent aluminum oxidation caused by long-term use of disinfection in the laboratory . The laboratory floor is made of imported plastic PVC Seamless floor connection , Acid and alkali corrosion resistance 、 Anti abrasion and anti slip .
