Question 9 LB01 - Lifeboat Operator

The Correct Answer is D **Why option D ("Automatically as the liferaft inflates") is correct:** Inflatable liferafts are critical safety devices used in emergencies, and their internal light must function immediately and reliably without requiring manual intervention from a potentially injured or panicked survivor. The liferaft's inflation mechanism often incorporates a hydrostatic release or pull cord system that activates the inflation cylinder. This same action or the resulting tension/pressure from the inflation process is used to pull a lanyard or close a switch that automatically activates the internal (and external) lights. This ensures the light is operational the moment the raft is properly deployed and inflated, aiding survivors trying to stabilize the raft or find essential gear inside. **Why the other options are incorrect:** * **A) By screwing the bulb in after the raft is inflated:** This requires a specific manual action, which is impractical and unsafe in an emergency at sea, potentially involving darkness, bad weather, and injury. Liferaft lights are designed to be ready for immediate use. * **B) At night via photosensitive switch:** While photosensitive switches are common in some lighting applications, relying solely on them for an emergency liferaft light is risky. If the raft is deployed during heavy fog, a storm, or a brief period of twilight, the light might not activate when needed most (e.g., to find internal equipment or signal to rescuers overhead). The light must be activated reliably upon deployment, regardless of ambient conditions. * **C) With a switch near the boarding handle:** Requiring a manual switch (even if conveniently located) adds an unnecessary step and potential point of failure. The design philosophy of emergency equipment dictates that essential safety features like lighting should activate automatically upon deployment to minimize human error and response time.
