The use of signage markings and personal discipline is the final control measure covered by ERICPD hierarchy. The reliance upon individuals following the sign’s direction is immense; it is also well known that an over provision of signage actually results in a person becoming ‘sign blind’ where they cannot identify what the specific signage denotes and will therefore not take the appropriate course of action – this will be discussed further in Chapter 10. All signs must display a pictogram to
identify their meaning which may, if necessary, be supported by suitable wording.
