🔍 Key Concepts

• Inflatable liferaft components such as pressure relief valves, inflation/air inlet valves, and painter/sea anchor gear • Typical location of a pressure relief valve on an inflatable liferaft buoyancy tube • Distinguishing small fittings on the tube from items like ladders, righting straps, and grab lines

💭 Think About

• On an inflated raft, where would excess air need to escape from to prevent over‑pressure: the canopy, the bottom, or the buoyancy tubes? • Which numbered item in the drawing is a small fitting mounted on the tube itself, rather than a line, strap, or opening? • Look at the items near the waterline versus those high on the canopy—where is a pressure‑controlling device most likely installed?

✅ Before You Answer

• Identify which numbers are clearly not valves (for example, drogue/sea anchor, painter line, ladder, canopy openings). Eliminate these first. • Among the remaining candidates, look for a small circular or plug‑like fitting attached directly to the raft tube, not hanging free or forming part of a line. • Confirm that the number you pick is on the buoyancy tube, not on the canopy, ladder, or external rigging.
