(a)he shall forthwith cause all persons employed in so much of that part as appears to him to be affected (hereinafter referred to as the " affected area ") to leave it;
(b)unless he is a manager of the quarry, he shall, forthwith after complying with the foregoing paragraph, inform his immediate superior or, in a case where he is responsible to two or more immediate superiors, each of them within whose jurisdiction any part of the affected area is situated, that the danger exists ;
(c)so soon after complying with paragraph (b) of this subsection (or, in a case where that paragraph does not apply, paragraph (a) of this subsection) as it is possible so to do without undue risk, he shall himself ascertain, or cause some competent person to ascertain, the condition of the affected area and the measures that it is necessary to take for the purpose of rendering it safe.
(2)Where, on any occasion, persons have been caused to leave an affected area in pursuance of the foregoing subsection, no person shall thereafter be permitted to enter it so long as the person in charge of it is not satisfied that it is free from all danger:
Provided that nothing in this subsection shall be taken to prohibit a person from entering an affected area for the purpose of saving life, giving effect to paragraph (c) of the foregoing subsection, rendering that area or any other part of the quarry safe, or ascertaining either the effectiveness of any measures taken for the last-mentioned purpose or whether, apart from this proviso, persons may lawfully be permitted to enter the affected area.
(3)Where persons have, on any occasion, been caused to leave an affected area in pursuance of subsection (1) of this section, the person who caused them to leave it shall record in a book to be provided for that purpose by the owner of the quarry particulars of the reason for his causing them to leave that area and of the matters disclosed as a result of giving effect to paragraph (c) of that subsection and subscribe his signature thereto.
