scope:

Methodologies are provided to perform visual inspection and evaluation of:

1. Directional airflow

2. Anterooms

3. Primary containment systems

4. Building ventilation system

5. Heating, ventilation, and airconditioning (HVAC) testing 6. Filtration

7. ABSL-3 and integration of individually ventilated caging, static caging systems, other elements; and downdraft tables

8. Document verification

9. Pressure reversal

10. Failure testing

11. Leakage issues related to HVAC

12. Qualifications of testers

ANSI Z9.14 focuses on performance verification of ventilation system-engineering controls and related systems within a BSL-3/ABSL-3 laboratory.

Testing and verification of ventilation systems in BSL-3/ABSL-3 labs include:

• Supply

• Exhaust

• Directional airflow

• Biosafety cabinets

• Air filtration

• Exhaust stacks

• Fan failure scenarios

• Redundancy

• Canopy hoods (autoclaves)

• Specific ABSL-3 requirements

Testing and verification of related systems within BSL-3/ABSL-3 labs include:

• Optimizing maintenance of pressure gradients and maintaining temperature and humidity

• Physical integrity

• Sealing and leakage factors

• Interlocking systems

• Airlocks

• Doors/windows

• Emergency and backup power systems

• Alarms

• Operating sequences

PURPOSE

The purpose of ANSI Z9.14 is to provide a "one-stop" resource for guidance to inspect and test the performance of a BSL-3/ABSL-3 laboratory ventilation system.
