This section provides guidance to schools on the establishment and implementation of policies and procedures
to promote the health and safety of all pupils and staff
by which school management ensures, so far as is reasonably practicable, that all children and young people are safe at all times when they are on school premises, (including the installation of suitable physical barriers, fencing, gates, locks on doors etc. and/or direct supervision so that no pupil is permitted in an insecure area unless under supervision).
