water supply and gas supply lighting system layout design
Non-manual hand washing facilities are set up in the laboratory protection area near the exit of the experimental room. If the laboratory does not have water supply conditions, a non-manual hand disinfection device should be set up; a backflow prevention device or Other effective devices for preventing backflow pollution, and these devices should be installed outside the protection area, and should be installed at the boundary of the maintenance structure in the protection area; the liquid and gas piping systems entering and leaving the laboratory should be firm, leak-proof, rust-proof and resistant. Pressure, temperature and corrosion resistance, there should be enough space to clean, maintain and repair the exposed pipes in the laboratory, and shut-off valves, backflow prevention devices or HEPA filters should be installed at key nodes; if there is a gas supply tank, etc., it should be It should be placed in a place where it is easy to replace and maintain outside the laboratory protection area, and the installation should be firm. Immiscible gases or liquids should not be placed together; if there is a vacuum device, there should be measures to prevent the interior of the vacuum device from being polluted. Install the vacuum unit outside the experimental site.
A pressure steam sterilizer that meets the biosafety requirements should be installed in the laboratory protection area, and a biosafety double-door pressure steam sterilizer should be installed. The connection should be sealed reliably; the installation position of the pressure steam sterilizer should not affect the airflow of the biosafety isolation device; the aqueduct for transferring the items can be set up as needed. To replace the disinfectant, the connection between the aqueduct and the enclosure structure should be reliably sealed; the ground liquid collection system should be equipped with a device to prevent liquid backflow; the drainage pipeline should be clearly installed, and there should be enough space to clean, maintain and repair exposed laboratory equipment. Pipes; if there is a sewer system in the pharma machinery protection area, it should be completely isolated from the sewer system of the building, and the sewer should directly lead to the sewage treatment system dedicated to the laboratory; all sewer pipes should have sufficient inclination and displacement to ensure that There is no water in the pipeline. The key nodes of the pipeline should be installed with anti-backflow devices, traps or closed valves as required. The supply of the sewer system should meet the corresponding requirements of pressure resistance, heat resistance and chemical corrosion resistance. It is convenient for maintenance, cleaning and inspection; the laboratory drainage system should be provided with a separate vent, and the vent should be equipped with a HEPA filter or other reliable disinfection device, and at the same time, good ventilation should be ensured at the vent. Disinfect and leak the HEPA filter in situ; the sewage in the auxiliary area of u200bu200bthe laboratory should be treated to meet the standard before being discharged into the municipal pipe network; it should be in the area where pollution may occur in the laboratory protection area, such as near biological safety cabinets and centrifuges etc., equipped with a portable disinfection device. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for laboratories and clean rooms.
The illumination in the core work room of the laboratory should not be lower than 350Ix, and the illumination in other areas should not be lower than 200
Ix, ceiling-type airtight waterproof and clean lighting should be used; excessive light and light reflection should be avoided; emergency lighting system and emergency lighting evacuation indication signs should be set up; laboratory automation control system should be controlled by computer central control system, communication The controller and the on-site execution controller should have the functions of automatic control and manual control. The emergency manual should have priority control and should have the hardware interlocking function; the laboratory automation control system should ensure the directional airflow in the laboratory protection area. The correctness and stability of the pressure difference; the interlock control program of the ventilation system should start the exhaust first, then start the supply, and close the supply and sealing valve first, and then close the exhaust and sealing valve; the ventilation system should be consistent with the biological safety The interlocking control of local exhaust equipment such as cabinets and fume hoods ensures the stable operation of the laboratory and maintains an orderly pressure gradient during the opening and closing of the laboratory ventilation system; it should be in a prominent position at the entrance of the room with pressure control requirements. Install a device to display room pressure; the signal acquisition interval of the central control system should not exceed 1 min, and each parameter should be easy to distinguish and identify.
