🔍 Key Concepts

• Cargo securing and lashing requirements for hazardous materials on deck • Difference between strong fixed structure vs. light/secondary structures (like rails) • Why transmission of load to the ship’s structure matters in a seaway

💭 Think About

• Which option provides a direct, strong connection to the vessel’s main structure so that dynamic loads from the cargo are safely carried? • In rough seas, which choice is least likely to fail or tear away if the hazardous cargo starts to shift or surge? • Which answer best matches what regulations expect for approved securing points rather than improvised or weak attachments?

✅ Before You Answer

• Check which securing point is part of the primary deck structure rather than a light or easily damaged fitting • Consider which method would most likely be explicitly allowed in hazardous-materials stowage regulations • Verify that the chosen method would prevent movement in all directions (fore‑and‑aft and athwartships) under heavy weather conditions
