(a) General.
(1) Two safe means of access and egress shall
be provided for all shafts and inclines. If a ladderway is used as one of the
means of access, it may terminate above the shaft bottom provided chain, wire,
rope or wooden extension ladders extend the remaining distance.
NOTE: Ramps for inclinations of 0° to 20° Stairways for inclinations of 20° to 45o Ladders for inclinations of 35° to 90°.
(2) No
shaft or incline used for hoisting shall have the center line of the ladder
width closer than 36 inches from any part of the moving skip, cage or bucket.
Unless the ladderway is in a separate, closed compartment, it shall be used
only in emergency or occasional service.
(3) All ladders shall be of such design,
material and construction that they will safely support all normal loads
imposed upon them.

ladderway more than 30 feet in length shall have an enclosed manway with
platforms at intervals not exceeding 20 feet or a ladder cage. In all vertical
shafts and where practicable in incline shafts (more than 60°), the
sections of the ladders shall be staggered at each platform so that no section
shall be directly in line with the section above or below it.
(5) All outside edges of platforms shall be
protected by standard guard railings.
(6) Ladders shall project at least 3 feet 6
inches above every platform and the collar of the shaft, unless convenient and
secure hand holds are fixed at such places.
(7) All ladders shall be securely
fastened.
(8) Under no
circumstances shall any ladder be installed inclining backward from the
vertical.
(9) Ladderways and
platforms shall be kept clear of loose rock and
obstructions.
