ALBERT C. RITCHIE, GOVERNOR. 723

SEC. 131. The mine foreman, whenever in his opinion the
mine is becoming dangerous from accumulations of gas, and
additional ventilation is required, beyond the capacity of the
ventilating equipment, shall notify the district mine inspector,
who shall make an immediate personal examination, and if
such inspector finds that the ventilating equipment is insuffi-
cient, he shall by special safety order require the operator to
provide adequate equipment, and if necessary to make addi-
tional openings from the surface, or bore holes to furnish a vent
in the case of gas accumulations.

CHAPTER XIX— Fire Bosses.

SEC. 132. The operator of every gaseous mine shall em-
ploy a sufficient number of fire bosses, each of whom shall
satisfy the operator of his competency, and shall have first
obtained a certificate of competency from the Examining
Board, as hereinbefore provided. Such fire boss shall care-
fully examine, before each shift enters the mine, every work-
ing place, all places adjacent to live workings, every road-
way, every unfenced road to abandoned workings, and falls
in the mine, the entrance to worked-out portions of such mine,
adjacent to roadways and working places under his charge,
within which accumulations of explosive gas may gather; and
at each working place such fire boss shall mark the date and
his initials upon the face. He shall note the air at every such
point, and shall see whether the air currents are traveling their
proper course; and wherever he finds explosive gas or other
danger, he shall either fence off the dangerous locality or place
warning signals across the passage way, ordering all persons
not to enter.

SEC. 133. Any mine foreman holding a first-class certificate
of competency may act as fire boss; and in an emergency any
fire boss, properly certified, may act as assistant mine fore-
man until a regularly qualified person may be employed.

SEC. 134. The operator shall provide a permanent station at
or near the principal entrance of the mine, indicated plainly
by legible signs, at which the fire boss shall attend before
men go in to their shifts, to give information regarding the state
of the mine. When the working portions of any mine are one
mile or more from the entrance to such mine or from the bot-
tom of the shaft or slope, a station may, with the approval of
the district mine inspector, be located near such workings. No
