The care which an occupier of premises is required, by reason of his occupation or control of the premises, to show towards a person entering thereon in respect of dangers which are due to the state of the premises or to anything done or omitted to be done on them and for which the occupier is in law responsible shall, except in so far as he is entitled to and does extend, restrict, modify or exclude by agreement his obligations towards that person, be such care as in all the circumstances of the case is reasonable to see that that person will not suffer injury or damage by reason of any such danger.

Nothing in the foregoing subsection shall relieve an occupier of premises of any duty to show in any particular case any higher standard of care which in that case is incumbent on him by virtue of any enactment or rule of law imposing special standards of care on particular classes of persons.

Nothing in the foregoing provisions of this Act shall be held to impose on an occupier any obligation to a person entering on his premises in respect of risks which that person has willingly accepted as his; and any question whether a risk was so accepted shall be decided on the same principles as in other cases in which one person owes to another a duty to show care.
