(225 ILCS 705/19.05) (from Ch. 96 1/2, par. 1905)
Sec. 19.05.
The escapement shaft at every mine opened after the
passage of this Act shall be equipped with a substantial stairway, set
at an angle not greater than forty-five degrees, which shall be provided
with hand rails and with platforms or landings at least 2 feet wide and
4 feet long at each turn of the stairway. However, circular escapement
shafts may be equipped with a substantial spiral stairway equipped with
hand rails, and set at an angle not greater than 45 degrees, and
platforms or landings are not required except at the top and bottom of
such spiral stairways. Subject to the approval of the Mining Board, at
any underground mine constructed with 3 or more shafts all of which are
within a radius of 400 feet and containing 2 or more hoisting systems, one
of which has an independent auxiliary power source, such mine may be equipped
with a substantial ladder system instead of the substantial stairway as
required by this Section. Such ladder system shall have intermittent platforms
at intervals not exceeding 20 feet. Such platforms shall be at least 2
feet wide and 4 feet long with adequate handrails. Each section thereof
shall be staggered and be provided with backguards extending from a point
not more than 7 feet from the bottom of each section of the ladder to the
top of that section.
