Definition
In the context of transporting dry ice aboard an aircraft, a storage container is any vessel or package used to hold the dry ice during flight. Because dry ice (solid carbon dioxide) sublimates into gaseous CO2 at normal temperatures, the container must be vented or non-airtight so that pressure cannot build up and gas can escape rather than accumulate in the cabin or cargo area.
Plain English
The box, cooler, or package that holds the dry ice while it is on the aircraft. It must let gas escape so pressure does not build up and so the cabin does not fill with carbon dioxide.
Context Anchor
Seen when preparing to carry dry ice or dry-ice-cooled items in an aircraft.
Derivation
Container comes from an older Latin idea meaning “to hold together.” That helps here because the key question is not just what the container holds, but whether it safely lets gas escape while holding it.
Why Pilots Care
An unsuitable container can cause pressure buildup or dangerous CO2 levels inside the aircraft.
Grounding Statement
A storage container for dry ice needs to hold the item while still giving the gas a way out.
Intuition Check
Do not assume a storage container should always be tightly sealed. With dry ice, a tightly sealed container can trap gas and build pressure; the safer container lets gas escape.
Example Sentence 1
Before loading the dry ice, the pilot confirmed the storage container was vented and not sealed shut.
Example Sentence 2
Pilots check that any storage container holding dry ice meets the venting requirements listed in the handbook.
