Large suites
Long visible paths and high ceilings can require high output and multiple delivery positions.
Contamination-control application
Pharmaceutical Aseptic-Processing Airflow Studies
Aseptic airflow visualization should show how engineering controls protect exposed sterile product, components and critical surfaces during representative operations and interventions. The fogger must serve the contamination-control question—not become the center of the study.
Start from the process risk map.
- Identify critical zones, open product and sterile pathways.
- Map HEPA supply, returns, barriers and known airflow transitions.
- List routine and non-routine interventions with contamination-control rationale.
- Define representative equipment, operator positions and material movement.
- Assign camera views and acceptance criteria to each scene.
- Then size fog generation, delivery and runtime for the complete sequence.
Where LN₂ output matters.
RABS lines
Extended barrier length and repeated interventions can drive runtime and multi-point delivery.
Isolators
Pressure and small openings can dominate over total output.
Background rooms
Room-wide mixing, door effects and return paths may need different settings from critical-zone views.
Evidence package.
| Record | Why it matters |
|---|---|
| Approved protocol and CCS link | Shows why each scene exists |
| Current fogger configuration | Connects evidence to controlled equipment |
| Fluid and accessory status | Supports tracer and delivery-path control |
| Environmental conditions | Explains condition-sensitive visibility |
| Raw and evaluated video | Preserves reviewability and integrity |
| Deviations/repeats | Prevents selective evidence |
