61. Underground workings, in particular shafts, sumps and winzes, which have been in disuse, shall be examined before being again used for the purpose of ascertaining whether foul air or other dangerous gases have accumulated therein. Only such workmen as may be necessary to make the examination shall be allowed to proceed therein until they are fit for use.
62. All parts of every underground working shall be properly and sufficiently ventilated to the satisfaction of a mines officer.
63. In every mine the quantity of air in circulation shall be measured, at least once per month, and entered in a book kept for the purpose at the mine.
64. All ventilation doors shall be self-closing.
65. Unless written exemption has been obtained from the Superintendent of Mines, percussive drills shall have a central water feed.
66. Adequate stationary lights shall be provided-
(a) during working hours--
(i) at all stations in vertical and inclined shafts; and
(ii) at all stopping places in levels where winding or hauling is effected by means of machinery; and
(b) at night, at all workings on the surface.
67. All places which contain winding, driving, pumping or other machinery in proximity to persons working and moving about and which are not fenced off in such a way as to render it impossible for anyone to come inadvertently in contact with the machinery shall be so lighted whilst in operation that the moving parts thereof shall be clearly distinguishable.
68. No person shall move about in any unilluminated part of a mine without showing a light.
