Biological safety cabinet maintenance and maintenance of standard operating procedures
1. The use of separate power supply to the biological safety cabinet, so as to avoid accidents caused by other equipment failure of the biological safety cabinet.
2. The top of the equipment ventilation can not be covered by anything to ensure smooth exhaust.
3. The equipment should be stopped when the alarm occurs, to identify the cause to ensure safety before use. If there is a system failure signal, because the air can not be effectively filtered and can not continue to use the equipment for operation.
4. Replacement of air filters should be contacted with the manufacturer's engineers, and replacement, laboratory staff can not be replaced privately, so as not to cause improper operation of the surrounding personnel and environmental pollution.
5. Used filters must be placed in a closed container, and in a clear position to indicate that it may contain dangerous microorganisms, attention and special treatment.
6. Newly purchased biological safety cabinets before use or maintenance after re-location must be certified by professional and technical personnel on the overall performance of the biological safety cabinets, each biological safety cabinets should be at least once a year to test and certify to ensure that the operation of the safety.
7. Biosafety cabinet performance tests should include: the speed of air supply and air supply volume test, inlet air intake velocity test, airflow smoke flow test, air filter penetration test, safety cabinet leakage test, electrical leakage and grounding resistance and polarity test, light intensity test, vibration test, noise level test, ultraviolet light test.
