🔍 Key Concepts

• Inflatable life raft construction – how buoyancy tubes are inflated and kept at the right pressure • Relief / topping‑up systems vs. deflation devices on modern SOLAS life rafts • What normally makes a continuous hissing sound immediately after inflation

💭 Think About

• Think about what happens inside the buoyancy tubes right after the raft inflates: is the pressure high, low, or changing? • Which components are designed to release gas, and which are designed to add gas? How would each one behave and sound? • Which option describes something that is directly connected to the buoyancy tube fitting where you hear the hissing, and which options describe unrelated equipment or unlikely malfunctions?

✅ Before You Answer

• Check which device is directly connected to the buoyancy chamber fitting that could hiss continuously after inflation. • Ask yourself whether marker light batteries or canopy equipment would produce a hissing sound at a tube fitting. • Consider whether a deflation plug is normally left partially open on a newly‑inflated, properly packed life raft, or whether there is another built‑in way for excess gas to escape if pressure is too high.
