š Key Concepts
ā¢ Cargo segregation methods: separate holds, tween decks, dunnage, plastic sheeting, tank liners
ā¢ Differences between contamination by contact vs contamination by odor or moisture transfer
ā¢ Operational issues like overcarriage, overstowage, short landing are usually solved by planning and documentation, not just physical separation
š Think About
ā¢ Which of these problems would still occur if the two cargoes were in the same hold but well separated by dunnage, tarps, or packaging?
ā¢ Which situation depends on cargoes being physically isolated by a steel boundary (separate hold) and cannot be fully prevented by coverings or careful stowage within one hold?
ā¢ Think about how smells, moisture, or dirt travel compared to solid contact. Which one really needs its own hold to avoid problems?
ā
Before You Answer
ā¢ Identify which options can be reduced by good stowage within the same hold (e.g., using dunnage, separation, tarps, labeling, and tallies).
ā¢ Identify the option where only a watertight/airtight structural barrier (separate hold) reliably prevents the issue.
ā¢ Eliminate any choice that relates mainly to paperwork, tally, or stowage planning errors, rather than physical cargo separation.
