The "Laboratory Biosafety Manual" proposes that biological safety cabinets can effectively reduce laboratory infections and cross-contamination of cultures caused by aerosol exposure. The biological safety cabinet can also protect the working environment.
In fact, biological safety cabinets are more focused on protecting operators and the environment, preventing the spread of pathogenic microorganisms in the operation, causing personal injury and environmental pollution.
Precautions for biological safety cabinets
1. Operators, if the biological safety cabinet is used improperly, its protective effect may be greatly affected.
2. Ultraviolet lamp, no ultraviolet lamp is needed in the biological safety cabinet. If you use a UV lamp, it should be cleaned weekly to remove dust and dirt that may affect its sterilization effect.
3. Open flames, in the environment with almost no microorganisms formed in the biological safety cabinet, the use of open flames should be avoided.
4. Overflow, laboratory operation rules on how to deal with spillage should be posted in the laboratory. Every member who uses the laboratory must read and understand these regulations.
5. Certification. During installation and after a certain period of time, qualified professionals should certify the operating performance and integrity of each biosafety cabinet in accordance with the manufacturer's instructions to check whether it meets national and international standards. Performance standards.
6. Cleaning and disinfection. Since the remaining medium may grow and multiply microorganisms, at the end of the experiment, all items in the biological safety cabinet, including instruments and equipment, should be cleaned of surface contamination and removed from the safety cabinet.
7. Decontamination, the biological safety cabinet must be decontaminated before moving and replacing the filter.
8. Personal protection, personal protective clothing should be worn when using the biological safety cabinet.
9. Alarm, you can choose one of two alarms to equip the biological safety cabinet.
