It shall be the duty of the operator of every mine in which oils and other dangerously inflammable materials are used, to store such materials, or cause them to be stored in a covered building kept solely for such storage, which building shall be at least 100 feet from any other building, shaft, tunnel, or other mine openings, and at least 300 feet from any powder magazine: Provided, that gasoline, naphtha, distillate, and fuel oils may be stored in a tank or tanks buried in the ground, which tank or tanks shall be provided with proper vents, and shall be placed at least 10 feet from any building, or 50 feet from any shaft, tunnel or other mine openings, and at least 300 feet from any powder magazine: And provided further, that lubricating oils may be stored in a well constructed, covered building, which shall be at least 10 feet from any building, and 50 feet from any shaft, tunnel, or other mine opening, and at least 300 feet from any powder magazine. No tank shall be installed from which liquid fuel is to be conducted by gravity to the point of combustion, unless there be installed between such tank and such point of combustion a simple and reliable cut-off valve which shall be capable of being reached and closed within 30 seconds from any point within the building in which such point of combustion is situated.
The person in charge of such building or tank or tanks, who shall be the superintendent or a person expressly designated by him or her, shall permit only sufficient oil or other inflammable material to be taken from such building or tank or tanks to meet the requirements of one day. If any oil or gasoline storage be so situated that leakage would permit the oil or gasoline to flow within the above specified distances, means to prevent such flow must be provided.
Illuminating oil shall not be stored in the underground workings of any mine, except such quantity as is sufficient to meet the estimated requirements of the mine during the succeeding 24 hours. No more than one barrel of any one kind of lubricating oil shall be stored underground on any one level at any one time. No oil, candles, explosives, timber, or other combustible materials shall be stored at all in shaft stations or within 50 feet thereof.
Gasoline shall not be stored underground: Provided, however, that a tank containing gasoline and connected to the engine or other apparatus in which it is being used shall not be construed as a storage tank. No engine or other apparatus shall be filled with gasoline while underground.
Waste timber or old timber shall not be piled and permitted to decay in stations, drifts, cross cuts, or other open workings in the mine, but shall be removed from the mine as soon as practicable: Provided, however, that in stopes or other workings, old timber may be buried in the filling material and permitted to remain in the mine. Empty boxes, wooden chips, paper, and combustible rubbish of all kinds shall be removed from every working place underground at least once in every 24 hours.
Timber storage sheds or any inflammable structure shall not be placed or permitted to remain within 75 feet of the shaft house or hoisting engine house: Provided, however, that wooden head frames for hoisting and lowering may be erected and operated.
All inflammable material that may be stored in any existing house or structure erected over any shaft, tunnel, or other mine opening shall be immediately removed, and such inflammable material shall not be stored within 30 feet of the exterior walls of such house or structure now existing, or that may hereafter be built.
All oily waste and waste of any kind used in and about underground machinery shall be deposited in metal receptacles.
Calcium carbide shall be stored on the surface only in detached, waterproof, dry, and well-ventilated buildings, and shall be contained in the original metal packages not exceeding 100 pounds each. All such packages, but one, in such storage place shall remain sealed except that a new package may be opened when in the only other open package there remains less than 1 pound of calcium carbide. No calcium carbide shall be stored underground.
