Biological Safety Cabinet Services

TSS offers comprehensive testing, certification and maintenance of biological safety cabinets. Our skilled technicians are authorized to perform warranty repairs for all major equipment manufacturers. All testing is performed in accordance with established TSS standard operation procedures [SOPs], which are updated to remain compliant with federal and international safety guidelines, current good manufacturing practices [cGMPs] and quality assurance systems.

Biological Safety Cabinets [BSCs] are certified to meet NSF-49, OSHA, NIH/CDC, and/or the manufacturer's specifications

Primary tests performed include:

• Inflow velocity profiling - assures that a safe inflow is maintained to protect the operator from the product, as well as the product from outside contamination
• Downflow velocity profiling - documents that the air in the work area is unidirectional and functioning as designed, preventing cross contamination
• HEPA filter integrity testing - tests filters and system for leakage/defects
• Fluorescent and UV light testing - establishes that the fluorescent lights are working at a level that will not contribute to worker fatigue and that the Ultra-Violet light is operating adequately
• Airflow visualization testing - Qualitatively verifies airflow direction using a source of visible fog
• Site installation testing and alarm calibration - assesses appropriate procedures for the installation of units for NSF and OSHA compliance

Optional tests include:

• Electrical safety testing - assures that the unit is electrically grounded and safe for worker use
• Pressure decay/cabinet integrity testing - establishes that there is no contamination escaping through the welds and joints
• Vibration testing - assures that product is not subject to damage due to vibration
• Sound testing - verifies that using the hood will not contribute to worker fatigue
