🔍 Key Concepts
• Cargo compatibility charts for chemical tankers (check how to read the matrix of "S"/"X"/blank entries)
• The difference between compatible, adjacent (compatible but with limitations), and must be segregated cargoes
• How alcohols, amines, and esters/monomers often behave with each other (polymerization / reaction risks)
💭 Think About
• Look up each pair: ethanolamine–methyl acrylate, ethanolamine–glycerine, and methyl acrylate–glycerine. For each pair, decide if they are compatible, only suitable for adjacent stowage, or must be segregated
• Ask yourself: is there any pair that is clearly compatible with both of the others? Or is there any pair that clearly must never be near each other? That will help you rule out some choices
• Think about which cargo (amine, monomer, or polyol) is most likely to create a dangerous reaction if it gets into the others, especially in terms of polymerization or uncontrolled reaction
✅ Before You Answer
• Verify in a recognized cargo compatibility source (e.g., IBC Code/compatibility tables or the exam’s provided compatibility chart) how each pair is marked
• Confirm whether "adjacent" stowage on the chart is treated the same as full compatibility or as a more restrictive condition than compatibility
• Before choosing, make sure your option fits all three binary combinations (each pair of cargoes) — not just one pair that you remember
