In isolators and RABS, delivery geometry matters as much as fog volume.
The study must place visible fog at the required location without creating a new obstruction or forcing the operator into the field being evaluated.
Map the system before writing the protocol
Identify glove ports, transfer systems, mouseholes, doors, filling paths, return-air locations, critical surfaces and operator interventions. Mark every required fog-release and camera location.
Control access and hose routing
Select hose diameter, length, adapters and wands that can reach the release point without kinking, dragging across critical surfaces or preventing normal operation. Remote controls may allow the fogger to remain outside a closed barrier.
Use the right output level
Small zones can become visually saturated. Begin with controlled output and increase only enough to make the airflow path clear. Medium and larger barrier systems may benefit from higher-output platforms or multiple outlets.
Document interventions and recovery
Capture the airflow response before, during and after representative interventions. Show whether protective flow is restored and whether any persistent turbulence or reverse flow develops.
