How to install a biological safety cabinet in a clean clean room modular?
The clean room biosafety cabinet is a defense device to ensure the safety of operators and surrounding personnel, and to isolate the pollution that occurs when dealing with pathogens in the operation area; the sealing of the biosafety cabinet is very important. During the handling process, it should be The packing box is moved into the clean room together, and unpacked at the construction site. It is not allowed to place and disassemble it horizontally, otherwise the sealing of the equipment after reset and assembly cannot be guaranteed; the installation location should avoid frequent crowds, and avoid The air flow in the room interferes with the air curtain of the operation port; pay attention to the distance between the back and the side from the wall. In order to facilitate the cleaning of accumulated dirt, it should generally be kept between 80-300mm. For the safety cabinet whose bottom and bottom are close to the ground, All seams along the edge should be sealed; after the biological safety cabinet has been running for a period of time, the high-efficiency filter for exhaust needs to be replaced frequently, and the connection method of the exhaust duct of the safety cabinet must be based on the principle of convenient replacement of the high-efficiency filter.
After the biological safety cabinet is installed or moved, relevant item tests must be carried out to ensure its technical performance and safety. When the design has no specified time, all joints, including the joints between the cabinet and the ground, must be sealed; After sealing, the pressure leakage test, the negative pressure test of the operation port, the leakage test of the high-efficiency air filter, the water leakage test of the washing basin, the air velocity test of the operation area and the operation port, and the grounding line resistance test of the grounding device should be carried out. The pressure leakage test shall confirm the air tightness of all joints and the entire equipment without air leakage; the negative pressure test of the operation port
, it should be confirmed that the airflow direction of the entire operation port is directed into the cabinet; the leakage test of the high-efficiency air filter should confirm that there is no leakage of the high-efficiency filter itself and its installation joints; the leakage degree of the washing basin should be confirmed to be full There is no water leakage in the washing basin of water after 1H; in the air velocity test of the operation area, it should be confirmed that the air velocity of the entire operation area meets the specified requirements; the airflow velocity test of the operation port should confirm that the air flow of the entire operation port meets the specified requirements; In the grounding line resistance test, it should be confirmed that the resistance of the grounding branch line at the wiring and socket does not exceed the specified value.
