Packaging, Wrapping & Storage Flashcards

What does 'first in, first out' (FIFO) rotation mean in sterile storage?

Answer: Oldest items (first sterilized) are used first to minimize shelf time

FIFO rotation ensures oldest sterilized items are used first, reducing prolonged storage that could lead to package compromise.

How far from exterior walls and ceilings should sterile packages be stored?

Answer: At least 2 inches from exterior walls; 18 inches from sprinkler heads

AAMI guidelines recommend storing sterile packages at least 2 inches from exterior walls (to prevent condensation) and 18 inches below sprinkler heads.

What is a 'sterile barrier system' (SBS) as defined by ISO 11607?

Answer: The minimum packaging that minimizes the risk of ingress of microorganisms and allows aseptic presentation

ISO 11607 defines the sterile barrier system as the minimum packaging needed to prevent microbial ingress while allowing aseptic opening.

What action should be taken when a sterile package is found to have a compromised seal?

Answer: Remove the item from service, reprocess and repackage the instrument

Any compromise to the sterile barrier renders the contents non-sterile; the item must be retrieved, cleaned, and reprocessed through the full sterilization cycle.

Why must paper-plastic peel pouches not be double-pouched (pouch inside a pouch) for steam sterilization?

Answer: Nested pouches prevent steam penetration to the inner pouch, compromising sterilization

Double-pouching (pouch-in-pouch) creates a dead space where steam cannot penetrate the inner pouch, resulting in sterilization failure.

What is the recommended temperature and humidity range for sterile storage areas?

Answer: 20–25°C (68–77°F) and less than 70% relative humidity

AAMI recommends sterile storage at 20–25°C with relative humidity below 70% to prevent condensation and packaging degradation.
