🔍 Key Concepts

• Ro-Ro (Roll-on/Roll-off) vessel design and how vehicle decks are arranged • Hazards of enclosed or partially enclosed vehicle decks (ventilation, exhaust, cargoes) • Typical personnel safety risks during vehicle loading/discharging

💭 Think About

• Ask yourself: What is the single condition that, if not controlled, could quickly become life‑threatening for many people below decks? • Consider which option addresses a continuous, hidden hazard that can build up during the entire loading/unloading process. • Which choice focuses directly on protecting personnel in the vehicle spaces, rather than on general shipboard routines or external traffic?

✅ Before You Answer

• Verify which option deals with conditions inside the vehicle decks during operations. • Check which hazard could cause serious injury or death even if everything else appears normal. • Ask: which choice is about immediate human safety, not just communication or convenience?
