If a laminar airflow workbench is turned off between aseptic processing sessions, how long should it run before it is used?

When a laminar airflow workbench is turned off between aseptic processing sessions, it is essential to allow the unit to run for a specific duration before reuse to ensure proper air quality and safe working conditions. The recommended duration for the workbench to run before it is used again is 30 minutes.

This timeframe allows the airflow system to reach optimal performance and air velocity, helping to effectively remove airborne contaminants and create a sterile environment. Continuous airflow helps maintain the clean air that is necessary to protect sterile preparations from possible microbial contamination.

Establishing a routine of allowing the laminar flow hood to run for this duration not only aligns with safety protocols but also adheres to best practices in sterile compounding. It accommodates the time needed for the unit to achieve the necessary flow patterns that ensure air quality is restored after being temporarily turned off.
