Initial Certification
Chapter 3: Getting Started
Prior to use, a qualified certifier should certify all Biosafety Cabinets. Under
normal operating conditions, the Biosafety Cabinet should be recertified at
least annually and when relocated or serviced. The certifier should perform
the following tests, as recommended in ANSI/NSF International Standard
Number 49 in effect when the cabinet was manufactured:
• Downflow Velocity Profile Test
• Inflow Velocity Test
• Airflow Smoke Patterns
• HEPA Filter Leak Test
• Vibration Test *
• Noise Level Test *
• Lighting Intensity Test *
*These tests are user comfort related tests and may be omitted at the
user’s or certifier’s discretion.
