Which action should you take first when you notice a MOB?

• A. Pass word to the bridge
• B. Call the coast guard
• C. Sound the alarm
• D. Deploy lifebuoy

Answer: (A)

When you notice someone overboard, the first step is to inform the bridge so they can initiate the MOB procedure. The bridge controls the vessel’s actions, coordinates the rescue, and calls in shore support if needed. Without quickly notifying the bridge, the crew can’t properly maneuver, alert others, or deploy the rescue plan, and precious seconds are lost.

Other actions like sounding the alarm, throwing a lifebuoy, or contacting the coast guard are important parts of the response, but they’re carried out under the bridge’s direction and as part of the coordinated MOB procedure. Notifying the bridge first ensures a rapid, organized response and proper use of rescue resources.
