Segregating cargo lines is about preventing cross-contamination and dangerous interactions when different cargoes are handled through the same system. Many cargoes are incompatible with one another—some react, some contaminate, and others can form hazardous mixtures if they come into contact. By keeping lines dedicated to specific cargoes or by routing transfer through separated, properly valved paths, you avoid unintended mixing during loading, unloading, or transfers. This reduces the risk of chemical reactions, spoilage, or safety hazards, and it also makes it easier to isolate problems if a leak or spill occurs. Other options don’t directly address the core risk—keeping incompatible cargoes apart to maintain safety and product integrity.
