Newly Released Z9.14 Standard for Lab Ventilation This Critical Standard is Now Available Through ABSA and ASSE!


On January 24, 2014, the American National Standards Institute (ANSI) approved the new standard, "Testing and Performance Verification Methodologies for Ventilation Systems for BSL-3/ABSL-3 Facilities" (ANSI/ASSE Z9.14-2014).

The American Society of Safety Engineers (ASSE) and the American Biological Safety Association (ABSA) take great pride in alerting the SH&E Community that this critical ventilation safety standard has now been released. Interest in this standard is significant and ASSE and ABSA are pleased to join forces in order to raise awareness of this important standard.


The ANSI/ASSE Z9.14 Standard focuses on performance verification of engineering controls related specifically to ventilation system features of BSL-3/ABSL-3 facilities. ANSI/ASSE Z9.14 uses a risk assessment and performance-based approach to provide the technical specifications and background information needed to address the technical, engineering, and associated systems for ventilation within a BSL-3/ABSL-3 laboratory. As such, it is fully compatible with biorisk-management systems and national and international health and safety management systems without duplicating or contradicting their requirements. The standard provides one component of a more extensive graduated and risk-based approach to reaching containment goals appropriate to the risk of the agent and the laboratory activity. Z9.14 is the only guidance that provides a methodology to verify ventilation systems in high containment facilities.
