Locations and health and safety

I will be filming at Mortimer's forest and The Linney forest which are both public locations , accessible to everyone , so i won't need permission.

My chosen location has a few hazards and dangers but most of them if they occurred would result in very minor injuries but can also be prevented by the people being more careful , cautious . Most of the filming takes place in a forest clearing , so i don't have to worry about people being in the way and any disturbances from other people and it's a very quiet area so all the filming should go as planned with out any unpleasnt surprises
My other location is the drama room because it contains the piano . 
I asked for permission from the drama teacher to film in the drama room  using facebook
