Information desks, rest areas, transportation terminals outside the venue and the administration building of each park-and-ride car park also function as a point of contact for lost children, providing services to ensure the safety and security of visitors. A Lost Child Centre has been set up at the Expo site to centrally manage information to ensure that lost children are taken into safe custody and returned to their guardians as quickly as possible. In addition, “lost child wristbands” are distributed at appropriate locations throughout the Expo site to ensure a quick and appropriate response to lost children.
