How do you troubleshoot common BSC problems and errors?

2 Inspect the filters

The filters are the key components of your BSC that remove airborne particles and microorganisms from the incoming and outgoing air. They need to be regularly inspected and replaced to ensure optimal performance and safety. You should follow the manufacturer's recommendations for filter maintenance and replacement, as well as the local regulations and standards for biohazardous waste disposal. Some signs that your filters may need attention include reduced airflow, increased noise, visible damage, or odor. If you suspect that your filters are compromised, you should stop using your BSC and contact a qualified technician for service.

3 Clean the work surface

The work surface of your BSC is where you place your materials and equipment for manipulation. It is exposed to potential contamination and spills, so it needs to be cleaned and disinfected before and after each use. You should use a suitable disinfectant that is compatible with your BSC and your biohazardous agents. You should also wipe down the walls, windows, and grills of your BSC with a damp cloth or paper towel. You should avoid using harsh chemicals, abrasives, or solvents that may damage your BSC or generate harmful vapors. You should also avoid over-wetting or flooding your work surface, as this may interfere with the airflow or damage the filters.

4 Test the airflow

The airflow is the main mechanism that creates a barrier between you and your biohazardous materials in your BSC. It is regulated by a fan and a vent system that draw air in and out of the BSC. The airflow should be balanced and consistent to prevent cross-contamination and exposure. You should test the airflow of your BSC regularly using a calibrated anemometer or a smoke test. You should also check the position and alignment of your BSC, as well as the surrounding environment, to avoid any obstructions or disturbances that may affect the airflow. You should report any deviations or fluctuations in the airflow to a qualified technician for adjustment or repair.

5 Verify the certification

The certification is the process of verifying that your BSC meets the required standards and specifications for performance and safety. It involves a series of tests and inspections that evaluate the airflow, filters, electrical system, alarms, and other components of your BSC. The certification should be performed by a certified professional at least once a year, or more frequently depending on the type and usage of your BSC. The certification should also be done after any relocation, modification, or major service of your BSC. You should keep a record of the certification results and dates for reference and compliance.

6 Consult the experts

If you encounter a problem or error with your BSC that you cannot resolve by yourself, you should consult the experts for assistance. The experts may include the manufacturer, the supplier, the service provider, or the biosafety officer of your institution. They can provide you with technical support, troubleshooting tips, repair services, or training resources. You should also follow their instructions and recommendations for using and maintaining your BSC safely and effectively. You should never attempt to fix or modify your BSC without proper authorization or qualification, as this may void the warranty, compromise the safety, or violate the regulations.
