Which factor must be considered when determining the order of loading of dissimilar products through the same piping system aboard a tanker?

Correct Answer: Option D — Contamination of the cargo

When utilizing shared piping systems for dissimilar products, cargo sequence must prevent inter-cargo contamination. Under 46 CFR and good liquid cargo handling practices, sequencing prevents off-spec product loss, chemical reactions, or toxic hazard creation by segregating incompatible grades effectively.
