(1) Save as otherwise provided in this rule, 5[the owner or agent] of every mine (hereafter in this rule referred to as the said person) wherein any women are employed or were employed on any day of the preceding twelve months, shall within such period as may be specified by the competent authority, construct thereat a creche in accordance with the standards prescribed under Rule 4:
Provided that where the competent authority is of opinion that the situation, nature and extent of the workings or other places where women are employed are such as to render compliance with the provisions of these rules not reasonably practicable, the competent authority may by order in writing exempt the said person from the provisions of these rules for such period as may be specified in the order subject to the condition that the competent authority may require the provision and maintenance of a suitable room or rooms with an attendant and necessary equipment at or near any working place or part of the mine:
Provided further that if the competent authority is satisfied that by reason of shortage of building material or of labour, the said person is unable to provide within the stipulated period a creche in accordance with the specifications in these rules, that authority may approve of the erection of a temporary structure to be replaced by a permanent structure within such time as he may prescribe.
(2) If the competent authority is of opinion that the conditions in any mine or part thereof are such as to render compliance with the said rule unnecessary, he may by order in writing and subject to such conditions as he may specify therein exempt the mine from the provision of a creche.
(3) If in any case the competent authority is satisfied that no inconvenience will be caused to the employees concerned, if a single creche is provided to serve neighbouring mines, he may authorise by order in writing 6[the owners or agents] of such mines to provide jointly a single creche and on such conditions as he may specify in the order.
(4) On the production of a certificate from the Chief Inspector of Mines that the productive capacity of a mine will be exhausted within three years from the date of the certificate, the competent authority may on condition that the said person shall provide a temporary structure to serve the purpose of a creche and on such other conditions as the competent authority deems fit, grant by order in writing exemption from the construction of a creche in accordance with these rules.
(5) Subject to such relaxations as may be considered necessary by the competent authority the provisions of Rules 5 to 13 shall also apply to every room or rooms provided under the first proviso to sub-rule (1) and to every temporary structure provided under the second proviso of sub-rule (1) and under sub-rule (4).
