Example Exam Question and Model Answer.

Health and Safety

Time for Geography takes great care in ensuring all aspects of health and safety are addressed when filming on location and appropriate safety equipment is used. Full risk assessments are carried out, before filming, by our experienced team of outdoor activity professionals. The use of certain locations by Time for Geography, in no way endorses these locations as being appropriate for geography fieldwork, to be carried out by either individual students, teachers or school groups. Any decision by either individuals or schools to use these locations is solely the responsibility of those individuals or establishments, who will need to carry out their own risk assessments.
