No one left behind: A universal design analysis of ship evacuation

An accident on a passenger ferry may lead to evacuation using lifeboats or liferafts, a process that can be both complex and hazardous. This paper investigates the level of safety for passengers during evacuation based on field study and interview data. In the analysis, the eight goals of Universal Design (UD) were tailored and used to explore what ship and interior characteristics influence evacuation performance and the demands placed on the crew and passengers, and whether all passengers have equal chances of completing evacuation safely. Results suggest that while a ship may fulfil regulation, completing an evacuation may pose challenges for passengers with varying abilities, for example, when attempting to perceive emergency information or move through the ship. In addition, it was found that an evacuation may present the crew with challenges and difficult trade-offs that are not always accounted for in the ship's design, equipment and safety organization. It is concluded that the use of a UD approach in ship design, based on a truthful representation of passenger demographics, could enhance passenger safety and provide for evacuation on equal terms.
