🔍 Key Concepts

• Cargo segregation requirements for incompatible chemicals on a multiple-product chemical tanker • How the IBC Code / 46 CFR chemical compatibility tables treat amines (like diethylenetriamine) vs amides (like formamide) • Differences between physical separation (bulkheads/void spaces) and operational controls (piping arrangements, valves, venting)

💭 Think About

• Ask yourself: when two cargoes are chemically incompatible, what is usually the first level of segregation required: common piping controls, separate venting, or tank-to-tank separation? • Compare the strength of each option: which choice describes the greatest physical separation, and which describes mainly operational precautions? How would that relate to highly reactive chemicals? • Think about typical segregation language: what does a requirement like a "void space or empty tank" vs. "single bulkhead" usually mean in terms of how serious the incompatibility is judged to be?

✅ Before You Answer

• Check which options talk about tank segregation (bulkheads/voids) versus system segregation (piping/venting). • Verify which measure would be required for reactive combinations that could cause a dangerous reaction if accidentally mixed. • Make sure the option you choose reflects a minimum regulatory requirement, not just a good practice that might be done voluntarily.
