🔍 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.

Advance the hose team into the room without any additional preparatory action

Cool adjoining horizontal and vertical surfaces before opening the door to extinguish the fire

Keep the door tightly closed until all the oil has been consumed by the fire

Only need to set up a hose team to cool the door, then open the door and extinguish the fire using a type B-II extinguisher
