You are on a vessel carrying liquefied butadiene in bulk. Which document is NOT required to be either in the wheelhouse or easily accessible to the person on watch while underway?

Correct Answer: Option A — Cargo manual

Title 46 CFR regulates hazardous materials and bulk liquefied gases. While shipping documents, cargo information cards, and the Certificate of Inspection must be readily accessible to the watchstander under specific dangerous cargo regulations, a comprehensive cargo manual is typically retained for operational engineering reference rather than immediate bridge navigation access.
