🔍 Key Concepts

• Cargo compatibility and segregation requirements in 46 CFR for carbon disulfide, diisopropylamine, and pyridine • Rules for common venting / common header systems on multi‑product tankships • Meaning of single vs. double barrier separation (cofferdams, voids, empty tanks) between incompatible cargoes

💭 Think About

• Look up each cargo individually in the CFR tables and note any special requirements about segregation and venting, especially for carbon disulfide. • Ask yourself which cargoes may share vapor spaces (common headers) and which must be kept completely isolated due to reactivity or vapor hazard. • Consider whether carbon disulfide is allowed adjacent to the other two cargoes at all, and if it is, how many structural barriers are required between them.

✅ Before You Answer

• Verify in the 46 CFR hazardous materials / tank vessel tables how carbon disulfide must be separated from amines such as diisopropylamine. • Check any special notes or footnotes on venting/headers for pyridine and diisopropylamine (whether common headers are allowed). • Confirm the exact barrier requirement (none, one, or two barriers) specified between carbon disulfide and diisopropylamine before choosing among the options.
