Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) Sling Use.
(1) Fiber rope slings made from conventional
three strand construction fiber rope shall not be used with loads in excess of
the rated capacities prescribed in Tables S-18 through S-21.
(2) Fiber rope slings shall have a diameter
of curvature meeting at least the minimums specified in Figures S-4 and
S-5.
(3) Slings not included in
these Orders shall be used only in accordance with the manufacturer's
recommendations.
(4) Natural and
synthetic fiber rope slings shall not be used for suspending personnel
platforms.
(b) Safe
Operating Temperatures. Natural and synthetic fiber rope slings, except for wet
frozen slings, may be used in a temperature range from minus 20° F to plus
180° F without decreasing the working load limit. For operations outside
this temperature range and for wet frozen slings, the sling manufacturer's
recommendations shall be followed.
(c) Splicing. Spliced fiber rope slings shall
not be used unless they have been spliced in accordance with the following
minimum requirements and in accordance with any additional recommendations of
the manufacturer:
(1) In manila rope, eye
splices shall consist of at least three full tucks, and short splices shall
consist of at least six full tucks, three on each side of the splice center
line.
(2) In synthetic fiber rope,
eye splices shall consist of at least four full tucks, and short splices shall
consist of at least eight full tucks, four on each side of the center
line.
(3) Strand end tails shall
not be trimmed flush with the surface of the rope immediately adjacent to the
full tucks. This applies to all types of fiber rope and both eye and short
splices. For fiber rope under one inch in diameter, the tail shall project at
least six rope diameters beyond the last full tuck. For fiber rope one inch in
diameter and larger, the tail shall project at least six inches beyond the last
full tuck. Where a projecting tail interferes with the use of the sling, the
tail shall be tapered and spliced into the body of the rope using at least two
additional tucks (which will require a tail length of approximately six rope
diameters beyond the last full tuck).
(4) Fiber rope slings shall have a minimum
clear length of rope between eye splices equal to 10 times the rope
diameter.
(5) Knots shall not be
used in lieu of splices.
(6) Clamps
not designed specifically for fiber ropes shall not be used for
splicing.
(7) For all eye splices,
the eye shall be of such size to provide an included angle of not greater than
60 degrees at the splice when the eye is placed over the load or
support.
(d) End
Attachments. Fiber rope slings shall not be used if end attachments in contact
with the rope have sharp edges or projections.
(e) Removal from Service. Natural and
synthetic fiber rope slings shall be immediately removed from service if any of
the following conditions are present:
(1)
Abnormal wear;
(2) Powdered fiber
between strands;
(3) Broken or cut
fibers;
(4) Variations in the size
or roundness of strands;
(5)
Discoloration or rotting;
(6)
Distortion of hardware in the sling.
(f) Repairs. Repairs shall only be made by
the manufacturer or equivalent entity. Only fiber rope slings made from new
rope shall be used. Use of repaired or reconditioned fiber rope slings is
prohibited.
(g) Employers must
ensure that natural and synthetic fiber-rope slings:
(1) Have permanently affixed and legible
identification markings as prescribed by the manufacturer, and that indicate
the recommended safe working load for the type(s) of hitch(es) used, the angle
upon which it is based, type of fiber material, and the number of legs if more
than one; and
(2) Not be used
without affixed and legible identification markings as required by subsection
(g)(1) of this section.
