Prep, Packaging & StorageQuestion 87 of 100
Why are corrugated cardboard shipping boxes prohibited in sterile storage areas?
a.Cardboard absorbs the humidity needed to keep packaging pliable
b.Cardboard blocks the airflow needed for positive pressure
c.Cardboard sheds particulate, can harbor insects and moisture, and comes from uncontrolled outside environments
d.Cardboard cannot be labeled with a lot control number
Explanation
External shipping cartons travel through warehouses and loading docks, so they carry dust, pests, and moisture into a clean environment and they generate fiber particulate when handled. Supplies are removed from shipping containers in a separate breakout area before entering sterile storage. Airflow, humidity balance, and labeling are not the reasons behind the prohibition.
