🔍 Key Concepts

• Overhaul phase of firefighting – what must be checked before saying a fire is completely out • Difference between fire under control vs fire out/cold • Hidden fire spread: bulkheads, insulation, void spaces, and hot spots

💭 Think About

• Ask yourself: Could a fire still be smoldering unseen, even if people can enter without SCBA (self‑contained breathing apparatus)? • Think about what can make a fire restart after it seems out – which choice (or combination) deals with that risk most completely? • Which items are absolutely necessary every time, and which might be helpful but not strictly required to say the fire is out?

✅ Before You Answer

• Verify which options relate to safety from reignition (hot spots, hidden fires) rather than crew comfort or convenience. • Consider whether knowing the exact cause of the fire is always possible before you can declare it out. • Check which condition(s) ensure the space will not flare up again after the fire party leaves.
