(225 ILCS 705/5.15) (from Ch. 96 1/2, par. 515)
Sec. 5.15.
He shall take daily barometer readings and record the
readings when men are in the mine, and keep a careful watch over all
ventilating apparatus and the air currents in the mine. When the
ventilating fan at any mine fails or stops, he shall take immediate
action to cut off the electric power and withdraw the workers from the
face regions of the mine. In gassy mines, if the ventilation is restored
within a reasonable time, the face regions and other places where
methane is likely to accumulate shall be re-examined by competent
personnel, and if such places are found to be free from explosive gas
the power may be restored and work resumed. If the ventilation is not
restored within a reasonable time all underground employees shall be
removed from the mine. In non-gassy mines, if the ventilation is
restored within a reasonable time, the power may be turned on and the
work resumed without the necessity of re-examination.
