Despite the best planning, the unexpected may happen during a visit and Visit Leaders have to be prepared to change and adapt as required. Experience and training will enable sound judgements to be made.
The Visit Leader and Visit Assistants should monitor the risks throughout the visit and take appropriate action as necessary. This is called dynamic risk assessment and includes knowing when and how to apply contingency plans where they are needed. It also includes heeding advice and warnings from those with specialist expertise or local knowledge (especially with regard to higher-risk activities).
The actions taken as a result of dynamic risks assessment may be recorded after the visit so that they can inform future planning.
