four feet, and not more than sixty feet apart, shall be made on one
side of the slope or mechanical haulage way and whitewashed. The
refuge holes shall be kept free from obstruction, and the roof and
sides made secure. (Sec. 932, 959; Penalty, Sec. 976.)


Sec. 932. [=Detached locomotive from moving train. Traveling way
where locomotive is detached.=] At a mine, or in any part thereof,
where a locomotive is detached from a moving train of cars for the
purpose of dropping such cars past the locomotive, and the haulage
way at such point is designated as the principal traveling way, a
traveling way, not less than three feet wide and separated from the
track by a pillar of coal or substantial fence, shall be provided at
one side of that portion of the track from where the locomotive will
be detached to the switch of the siding. Such traveling way shall be
made on the same side of the track as the refuge holes. In no case
shall a locomotive be detached from a train of moving cars, for the
purpose of making a drop thereof, more than one hundred feet from
the switch of the siding. (Sec. 931, 959; Penalty, Sec. 976.)


[=Additional means of egress when inundation is probable.=] At any
mine where there is a stream or body of water on the surface, or in
the workings of a mine, at a higher level, which is likely to break
through into such mine and inundate either the traveling or
escapement way of such mine, so as to prevent the egress of persons
employed therein, the owner, lessee or agent, shall, upon the
written order of the chief inspector of mines, provide and maintain
an additional opening by means of which such persons may escape
without using the traveling or escapement way likely to be
