🔍 Key Concepts

• Behavior of a large fuel oil (Class B) fire in an enclosed machinery space • Importance of boundary cooling (cooling decks, bulkheads, and overheads) before entering a space • Dangers of opening a hot, confined space with a well‑developed fire (flashover, fire spread through decks and bulkheads)

💭 Think About

• Look closely at Figures 1–3: where is the heat and smoke traveling once the fire develops in the room accessed through door E? • Before sending a hose team through door E, what must you do to prevent the fire from spreading to compartments A, B, C, and D? • Which option shows a planned, indirect attack that controls heat transfer and fire spread, rather than rushing the team straight into the compartment?

✅ Before You Answer

• Identify which choice mentions cooling adjoining horizontal and vertical surfaces (decks and bulkheads) – that’s boundary cooling. • Eliminate any options that either (a) send the team in immediately with no prep, or (b) rely only on a portable extinguisher for a large machinery‑space fuel fire. • Consider whether it is ever acceptable to simply keep the door closed and let all the oil burn in a machinery space on a ship.
