🔍 Key Concepts

• Think about boundary cooling: you are not attacking the seat of the fire, you are cooling the deck/overhead above it from a safer adjacent space. • Look carefully at the red arrows in Figure 1 that show heat and smoke flow paths. Which hose position is directly in that flow and which is shielded by bulkheads? • Remember that hose teams should avoid standing in the path of hot gases venting from the fire compartment, and should use structure (decks/bulkheads) for protection.

💭 Think About

• Which hose line lets the team cool the upper boundary (the deck above the fire) while staying outside the fire compartment and out of the direct smoke/heat exhaust? • If the fire suddenly intensifies or flashes over, from which hose position would escape be more difficult because you are in the exhaust path or near the opening? • Boundary cooling can often be done from the deck above or from a protected passageway. Which hose location best matches that idea in the illustration?

✅ Before You Answer

• Confirm which hose is positioned inside vs. outside the main smoke/heat flow shown by the red arrows. • Check that the chosen hose has a protected approach and retreat route (ladder, passageway, door) not blocked by the fire’s exhaust. • Verify that the hose you pick can still direct water onto the overhead/upper boundary of the fire compartment, not just at floor level or directly into the opening.
