On all field trips and site visits there must be a recognised leader, whose identity is known to all participants. In most cases this will be a member of staff, but it is important that, where small groups of students are unaccompanied, one person is appointed and acknowledged as leader. All participants in a field trip have a responsibility to adhere to sensible standards of behaviour.
Every individual is responsible, by law, for the observance of safety provisions.
No-one may visit any building site without wearing an approved safety helmet at all times, properly adjusted to fit securely. Avoid ladders and scaffolding unless this is approved by both the Contractor and the leader of the group, in which case take special care and watch out for those above and below you. In any event, whenever working in small groups, ensure that your intentions are known to a responsible person who will start an enquiry if you are late in returning from the site.
