Final answer:
A medipak aboard an aircraft or a cruise ship is identified by a placard or through safety briefings by the crew, indicating its availability and location for emergencies.
Step-by-step explanation:
The notification that there is a medipak on board is typically left by the crew of an aircraft or a cruise ship in what is called a 'placard' that is often found in the cabin for passengers. This is done as part of the safety protocols to ensure that all passengers are aware that medical aid is available in case of an emergency. Airlines and marine transportation providers are required to have medical kits available, and thus they leave noticeable markers or directions pointing to their location. These notifications are also a part of the briefing provided by the flight attendants or crew before departure.
For commercial airlines, there will usually be an announcement or a section in the pre-flight safety briefing where the existence and location of the medipak (also known as an emergency medical kit or first aid kit) are disclosed to the passengers. Similarly, on a cruise ship, information regarding the medipak can be found in the ship's safety brochure or announced during safety drills. The exact location can vary, but it's commonly found in overhead compartments or marked storage areas that are easily accessible.
