Sec.  77.1908  Hoist installations; use.

    (a) Where men are transported by means of a hoist and the depth of 
the shaft exceeds 50 feet, the hoist rope shall be suspended from a 
substantial hoisting installation which shall be high enough to provide 
working clearance between the bottom of the sheave and the top of the 
cage or bucket.
    (b) Where men are transported by means of a hoist and the depth of 
the shaft exceeds 100 feet, temporary shaft guides and guide 
attachments, or other no less effective means, shall be installed to 
prevent the cage, platform, or bucket from swinging.
    (c) All guides and guide attachments, or other no less effective 
means, installed in accordance with paragraph (b) of this section shall 
be maintained to a depth of not less than 75 feet from the bottom of the 
shaft.
    (d) Where crossheads are used, the cage, platform, or bucket shall 
not be hung more than 10 feet below the crosshead.
    (e) Where men are required to embark or disembark from a cage, 
platform or bucket suspended over or within a shaft, a loading platform 
shall be installed to insure safe footing.
    (f) During the development of each slope or shaft, either a ladder 
or independently powered auxiliary hoist shall be provided to permit men 
to escape quickly in the event of an emergency.
    (g) No person shall be permitted to ride the rim of any bucket or on 
the top of a loaded bucket.
    (h) The number of persons permitted to ride in cages, skips, or 
buckets shall be limited so as to prevent overcrowding.
    (i) Persons shall not be permitted to ride on a cage, skip, or 
bucket with tools or materials, except when necessary to handle 
equipment while in transit. Materials shall be secured to prevent 
shifting while being hoisted.
    (j) The speed of buckets transporting persons shall not exceed 500 
feet per minute and not more than 200 feet per minute when within 100 
feet of any stop.
    (k) A notice of established speeds shall be posted in clear view of 
the hoistman.
    (l) Conveyances being lowered in a shaft in which men are working 
shall be stopped at least 15 feet above such men and shall be lowered 
further only after the hoistman has received a signal that all men who 
may be endangered by the conveyance are in the clear.
    (m) No skip or bucket shall be raised or lowered in a slope or shaft 
until it has been trimmed to prevent material from falling back down the 
slope or shaft.
    (n) Measures shall be taken to prevent material from falling back 
into the shaft while buckets or other conveyances are being unloaded.
    (o) Properly attached safety belts shall be worn by all persons 
required to work in or over any shaft where there is a drop of 10 or 
more feet, unless other acceptable means are provided to prevent such 
persons from falling into the shaft.
