  "text": "(1) No auxiliary fan shall be installed at any place in a mine unless the manager is satisfied—\n(a) that the quantity of air reaching it at all times will be sufficient to ensure that it does not re-circulate air; and\n(b) that air circulated by it will not be contaminated by any substantial quantity of any noxious gas or dust;\nand no such fan shall be worked at any time at which either of those conditions is not satisfied.\n(2) No auxiliary fan shall be installed at a point within, or less than fifteen feet from the nearer side of the entrance to, the place to be ventilated by it, so however that in the case of two or more fans installed in series this requirement shall apply only to one of them.\n(3) Any forcing auxiliary fan shall be installed on the intake side and any exhaust auxiliary fan on the return side of the place to be ventilated by it.\n(4) There shall be installed and maintained with every auxiliary fan such an air duct for conducting air to or from the face of the place to be ventilated as ensures adequate delivery of air within fifteen feet of the face and minimises leakage.\n(5) Every auxiliary fan, whether driven electrically or otherwise, shall be so connected with earth as to prevent the accumulation of an electro-static charge.",
