Muster station rules are governed by international maritime law, specifically the SOLAS (Safety of Life at Sea) convention, which requires all passengers to participate in a safety briefing before a ship departs. In 2026, many major lines like Carnival and Royal Caribbean utilize "e-muster" technology. The rule is that passengers must first watch safety videos on the cruise app or stateroom TV, then physically visit their assigned muster station (a designated emergency assembly point) to have their keycard scanned by a crew member. You are required to know the location of your station, which is found on the back of your cabin door and on your "Sign & Sail" card. During a real emergency, the general emergency signal is seven short blasts followed by one long blast of the ship's horn. When this sounds, the rule is to proceed immediately to your station, typically with your life jacket, warm clothing, and essential medications, following the low-level lighting and crew instructions.
