(a) The duties of the mine foreman shall be to keep a careful watch over the ventilating apparatus, the airways, traveling ways, pumps and drainage. He or she shall see that, as the miners advance their excavations, proper breakthroughs are made so as to ventilate properly the mine; that all loose coal, slate and rock overhead in the working places and along the haulways are removed or carefully secured so as to prevent danger to persons employed in such mines, and that sufficient suitable props, caps, timbers, roof bolts or other approved methods of roof supports are furnished for the places where they are to be used and delivered at suitable points. The mine foreman shall have all water drained or hauled out of the working places where practicable, before the miners enter, and such working places shall be kept dry as far as practicable while the miners are at work. It shall be the duty of the mine foreman to see that proper crosscuts are made, and that the ventilation is conducted by means of such crosscuts through the rooms by means of checks or doors placed on the entries or other suitable places, and he or she shall not permit any room to be opened in advance of the ventilation current. The mine foreman, or other certified persons designated by him or her, shall measure the air current with an anemometer or other approved device at least weekly at the inlet and outlet at or near the faces of the advanced headings, and shall keep a record of such measurements in a book or upon a form prescribed by the director. Signs directing the way to outlets or escapeways shall be conspicuously placed throughout the mine.

(b) After July 1, 1971, hinged man doors, at least thirty inches square or the height of the coal seam, shall be installed between the intake and return at intervals of three hundred feet when the height of the coal is below forty-eight inches and at intervals of six hundred feet when the height of the coal is above forty-eight inches.

(c) The duties of the mine foreman and assistant mine foreman shall include the instruction of apprentice miners in the hazards incident to any new work assignments; to assure that any individual given a work assignment in the working face without prior experience on the face is instructed in the hazards incident thereto and supervised by a miner with experience in the tasks to be performed.
