🔍 Key Concepts

• How fires can remain hidden inside soft materials like mattresses even after visible flames are gone • The difference between cooling/extinguishing a fire and preventing it from rekindling • Why smoldering embers in upholstery are especially dangerous on a vessel

💭 Think About

• If the outside of the mattress is wet and cool, could any heat or embers still be trapped inside? • Which option best reduces the chance of the fire rekindling without adding new hazards (like fumes, CO₂ exposure, or extra ignition sources)? • On a ship, what is the safest way to confirm a deep-seated fire in soft material is completely out?

✅ Before You Answer

• Verify which choice involves physically checking the interior of the mattress, not just the surface • Identify which options might still allow hidden hot spots or embers to remain • Eliminate any options that focus on storage or drying instead of thorough fire overhaul
