🔍 Key Concepts

• Requirements for remote shutdown of cargo systems on vessels carrying Liquefied Flammable Gases • Purpose of having remote controls in separate, safe locations in case one area is not accessible • Distinction between the valves themselves and the locations of the controls for quick-closing shutoff valves

💭 Think About

• If a fire or gas leak occurs in the cargo area, from how many different safe places should the crew be able to quickly close the valves? • Think about what would happen if one control station is blocked by fire or gas—what do regulations typically require for redundancy? • Are the controls usually grouped in only one place, or spread between different key locations on the vessel?

✅ Before You Answer

• Check how many separate locations (not just individual buttons) are required for remote operation of quick-closing valves • Verify whether regulations mention both sides of the vessel, cargo control room, or deck as typical locations • Confirm that the requirement is about minimum number of locations, not the number of valves or the number of individual control points at each location
