(a) the occupier or apparent occupier for the time being of the place;
(b) if members of a designated work group are affected in any way by the entry, a health and safety representative for the designated work group.
(2) However, an inspector is not required to notify, or produce his or her identity card for inspection by, a person if—
(a) to do so would defeat the purpose for which the place was entered or cause unreasonable delay; or
(b) the person is already aware that the inspector has entered the place or was notified in advance of when he or she would enter.
