Registering visitors - all visitors should be registered and given some form of indentification.
Visitors, especially in large settings, should sign in on arrival and out on leaving.
Accompanying visitors - all visitors are to be accompanied whilst in the building and should not be left alone with any children unless it has been specifically cleared for the visitor to do so.
Being alone with a child or young person - when alone with a child, it is important to remember the concept of openness. This could include letting a colleague know where you are going, leaving the door of the room you are in open or making sure you are sitting where you can be seen by others.
