but if not feasible and practical then the Bureau shall have
the authority to prescribe rules relating to the duties of
the door attendant.

89. (a) Hoisting. A qualified hoisting engineer shall be
on duty continuously when men are underground at shaft
mines.

Hoists used for handling men shall be equipped with
overspeed, overwind, and automatic stop controls, unless a
second engineer is on duty.

At the beginning of each shift and after the hoist has
been idle, the hoisting engineer shall operate the cages
up and down the shaft at least one round trip before hoist-
ing or lowering men. Similar procedure shall be followed
in slope hoisting, except that an attendant may ride on the
trip.

(b) Slope, shaft, or incline-plane hoists shall be
equipped with brakes capable of stopping and holding the
fully loaded unbalanced cage or trip at any point in the
shaft, slope, or on the incline.

An accurate and reliable indicator, showing the posi-
tion of the cage or trip, shall be placed so as to be in clear
view of the engineer, unless the position of the car or trip
is clearly visible to the engineer at all times.

Hoisting equipment shall be inspected daily and a record
made of such inspection which shall be open for inspection
by interested persons.

(c) Hoisting ropes on all cages or traps shall be ade-
quate in size to handle the load and have a proper factor
of safety as defined in the American Standard Associa-

(d) Cages, shafts, and slopes. Cages used for hoisting
men shall be of substantial construction; with adequate
steel bonnets; with enclosed sides; with gates, safety
chains, or bars across the ends of the cage when men are
being hoisted or lowered; and with sufficient handholds
or chains for all men on the cage to maintain their balance.
The floor of the cage shall be constructed so that it will
be adequate to carry the load so that it will be impossible
for a workman's foot or body to enter any opening in the
bottom of the cage.

Cages used for handling men shall be equipped with
safety catches that act quickly and effectively in an emer-
gency.

(e) Cages shall be inspected daily. A test of safety
catches on cages shall be made at least every two (2)
