This is a rescue staircase concept for a large passenger ship. In the event of an accident at sea in which the ship capsizes, exits would come to face the ceiling as the hull raises. In this case, passengers cannot escape through the exits, resulting in loss of human lives. Rescue Axis Stairs demonstrates how a rolled ladder embedded in the door during normal operation drops toward people who could not otherwise escape after the cover opens automatically if the ship inclines above a certain angle. The product has a lighting function as an emergency device to let passengers escape quickly in a darkened space.
