Students warned of hazard. Clothing or suncream worn.
For parties of 5 or less this should be obvious, but if spread out along shore and not visible to each other, one member designated to make regular checks on other members.
For larger parties, register taken, and all party members counted at intervals throughout fieldwork and conclusion (e.g. counted onto bus). Students asked to notify if any colleagues missing during trip. Large groups split into smaller groups with a designated person to count their group. Each group carries mobile phone.
All field work must be notified on the field work reporting form, and the return of the party notified.
