🔍 Key Concepts

• 46 CFR Subchapter I – Cargoes requirements for dangerous cargoes like chlorine • Special precautions for toxic-inhalation hazard (TIH) cargoes on barges in tow • What items must be physically present and posted versus operational practices underway

💭 Think About

• Think about which options describe administrative documentation and which describe operational safety precautions for a hazardous cargo like chlorine. • Ask yourself: for a gas that is extremely toxic if released, what kinds of protections would regulations tend to require for the structure of the barge, the information available to the pilot, and the watchstanding? • Consider whether regulations normally require only one type of protection for such hazardous cargo, or a combination of several layers of protection.

✅ Before You Answer

• Verify whether regulations require a cargo information card or similar written information in the pilothouse for hazardous cargoes in tow. • Consider if there are rules about keeping certain spaces closed (like wing voids) on a loaded chemical barge while underway. • Check whether a dedicated watch on the dangerous cargo barge is a typical regulatory requirement, especially for highly toxic cargoes.
