Question 11 QMED02 - Electrician-Refrigerating Engineer

The Correct Answer is B **Explanation for Option B (Dismissal from fire and emergency.) being correct:** The internationally recognized and standard signal for "Dismissal from Fire and Emergency" (or "All Clear") is the sounding of the ship’s general alarm or whistle for three (3) general blasts, supplemented by three (3) short blasts. This signal indicates that the immediate emergency (fire or other general emergency) is over and personnel can stand down or return to normal duties. **Explanation for why other options are incorrect:** * **A) Dismissal from a boat drill:** A boat drill (or muster for drill) usually ends with a simple announcement or a specific "All Clear" signal defined by the vessel's internal procedures, but it does not typically use the standardized 3 general blasts + 3 short blasts signal, which is reserved for ending an *actual* general emergency or major drill. * **C) Abandon ship:** The standard international signal for "Abandon Ship" is a rapid succession of seven (7) or more short blasts followed by one (1) long blast of the whistle or siren, or a continuous ringing of the general alarm bell. The signal given (3 general blasts + 3 short blasts) is distinctly different. * **D) Fire and emergency:** The signal for "Fire and Emergency" (or "General Alarm") is typically the continuous sounding of the general alarm bell or whistle for a period of at least 10 seconds, not the specific sequence of 3 general blasts supplemented by 3 short blasts, which is the *all-clear* signal.
