🔍 Key Concepts

• Behavior of burning jet fuel on decks and near structures • Layout of a MODU (Mobile Offshore Drilling Unit) – proximity of helideck to quarters and vital spaces • How fires spread horizontally versus vertical damage to the helicopter itself

💭 Think About

• Which hazard is most likely to spread the fire to living quarters or other critical areas of the MODU? • Which danger, if it occurred, would cause the greatest risk to personnel and the unit, not just the helicopter? • Think about what happens if fuel escapes the helicopter and how the deck drainage or lack of it might affect fire spread.

✅ Before You Answer

• Identify which option involves fire spreading away from the helicopter itself • Consider which option could threaten accommodation spaces, escape routes, or vital equipment • Eliminate choices that focus only on damage to the helicopter rather than overall MODU safety
