Level 3 Biosafety Installation Requirements
The power supply of the third-level biosafety laboratory meets all the power requirements of the laboratory and should have redundancy; a special distribution box should be set up in a safe location; biological safety cabinets, air supply fans, exhaust fans, automatic control systems, lighting, Monitoring and alarm systems should be equipped with uninterrupted backup power supply, and the power supply should be maintained for at least 30 minutes. Lighting system requirements: The illuminance of the core work room of the laboratory should not be less than 350Ix, and the illuminance of other areas should not be less than 200Ix. Ceiling type waterproof and clean lighting should be used; an emergency lighting system of not less than 30min should be set up; Strong light and light reflections.
Requirements for laboratory communication system: facsimile machines or other electronic equipment for transmitting data and data to the outside should be set up in the protected area; the complexity of the communication system should be adapted to the scale and complexity of the laboratory; the monitoring room and the laboratory should be A voice communication system is installed. If an intercom system is installed, a selective call method with controlled inbound calls and uncontrolled outbound calls should be adopted. The enclosure structure of the laboratory should be able to withstand the air pressure load caused by the abnormal supply fan or exhaust fan; the pressure difference between the air pressure in the core work room of the laboratory and the outdoor atmospheric pressure should not be less than 30Pa, and the pressure difference with the adjacent area should not be less than 30Pa. Less than 10Pa; under special circumstances, the pressure difference between the core working room of the laboratory and the outdoor atmospheric pressure should not be less than 40Pa, and the pressure difference with the adjacent area should not be less than 15Pa; the temperature should be controlled within the range of 18-26℃; protection The minimum ventilation frequency of each room in the area should not be less than 12 times/H; the relative humidity of the pharma machinery should be controlled at 30%-70%, and the relative humidity should meet the technical requirements of disinfection and sterilization in the disinfection state; open in the safety cabinet Under normal circumstances, the noise in the core work room should not be greater than 68dB(A). Zhongjing Global Purification can provide consulting, planning, design, construction, installation and transformation of biosafety laboratories and microbiology laboratories and other supporting services.
The door entering the laboratory should have an access control system, which should ensure that only authorized personnel can enter; the interlock of the door can be released immediately when necessary, and an emergency manual release interlock switch should be set near the interlock door; start the experiment When the room ventilation system is used, the exhaust air should be started first, and then the laboratory air supply should be started. When shutting down, the safety isolation devices such as the biological safety cabinet and the airtight valve of the exhaust branch pipe should be closed first, and then the laboratory air supply and airtight valve should be closed. exhaust and airtight valves; there should be a device at the entrance of the buffer room of the core working room to indicate the working status of the core working room, and if necessary, an interlocking mechanism to restrict access to the core working room should be set at the same time; when the exhaust system fails, There should be a mechanism to avoid positive pressure in the laboratory and affect the directional airflow; when the air supply system fails, there should be a mechanism to prevent the negative pressure in the laboratory from affecting the safety of laboratory personnel and affecting the normal function of safety isolation devices such as biological safety cabinets and maintain the integrity of the structure; a device should be set up to continuously monitor the resistance of the HEPA filter in the air supply and exhaust system, and the HEPA filter should be replaced in time when necessary; a device should be installed at a prominent position at the entrance of the room that requires negative pressure control to display the negative pressure of the room. Pressure display device and control interval prompt; the central control system should be able to monitor, record and store in real time the parameters required for control in the pharma machinery protection area, the operation status of key facilities and equipment, and should be able to monitor, record and store the phenomenon of failure and the time of occurrence It should be possible to view historical records at any time; the signal acquisition interval of the central control system should not exceed 1 minute, and each parameter should be easy to distinguish and identify; monitors should be set up in key parts of the laboratory, which can be monitored and recorded in real time when needed For laboratory activities and surrounding conditions, the monitoring equipment should have sufficient resolution, and the image storage medium should have sufficient data storage capacity.
