Cruise ship employees are responsible for keeping guests happy and calm, even in the case of an emergency aboard the ship. Some more alarming situations which cruise ship employees can encounter have their own secret code words understood by fellow crew members. Code Adam means a child is missing. Code Bravo is an alert that there is fire aboard the ship. If there is a medical emergency, crews will be talking about a Code Alpha, and if there is ever a man overboard crews will be communicating about a Code Oscar.
