In all mines generating methane in such quantities as to be considered a gaseous mine under section 1563.02 of the Revised Code, the mine foreperson of such a mine shall:
No person shall enter the mine until the fire bosses return to the mine office on the surface, or to a station located in the mine, where a record book as provided for in this section shall be kept and signed by the person making the examination, and report to the oncoming mine foreperson that the mine is in safe condition for the employees to enter. When a station is located in any mine, the fire bosses shall sign also the report entered in the record book in the mine office on the surface. The record books of the fire bosses shall at all times during working hours be accessible to the deputy mine inspector and the employees of the mine.
In every mine generating explosive gas in quantities sufficient to be detected by an approved flame safety lamp, when the working portions are one mile or more from the entrance to the mine or from the bottom of the shaft or slope, a permanent station of suitable dimensions may be erected by the mine foreperson, provided that the location is approved by the deputy mine inspector, for the use of the fire bosses, and a fireproof vault of ample strength shall be erected in the station of brick, stone, or concrete, in which the temporary record book of the fire bosses, as described in this section, shall be kept. No person, except a mine foreperson of gaseous mines, and in case of necessity such other persons as are designated by the mine foreperson, shall pass beyond the permanent station and danger signal until the mine has been examined by a fire boss, and the mine or certain portions thereof reported by the fire boss to be safe.
This section does not prevent a mine foreperson or foreperson of gaseous mines from being qualified to act and acting in the capacity of fire boss. The record book shall be supplied by the division and purchased by the operator.
No mine foreperson or person delegated by the mine foreperson, or any operator of a mine, or other person, shall refuse or neglect to comply with this section.
