be proof-tested prior to use to 125 percent of their rated load.
§ 1926.251
(5) Scope. This section applies to
slings used in conjunction with other
material handling equipment for the
movement of material by hoisting, in
employments covered by this part. The
types of slings covered are those made
from alloy steel chain, wire rope, metal
mesh, natural or synthetic fiber rope
(conventional three strand construction), and synthetic web (nylon, polyester, and polypropylene).
(6) Inspections. Each day before being
used, the sling and all fastenings and
attachments shall be inspected for
damage or defects by a competent person designated by the employer. Additional inspections shall be performed
during sling use, where service conditions warrant. Damaged or defective
slings shall be immediately removed
from service.
(b) Alloy steel chains. (1) Welded alloy
steel chain slings shall have permanently affixed durable identification
stating size, grade, rated capacity, and
sling manufacturer.
(2) Hooks, rings, oblong links, pearshaped links, welded or mechanical

month in which each alloy steel chain
sling was thoroughly inspected, and
shall make such record available for
examination.
(c) Wire rope. (1) Tables H–3 through
H–14 shall be used to determine the
safe working loads of various sizes and
classifications of improved plow steel
wire rope and wire rope slings with various types of terminals. For sizes, classifications, and grades not included in
these tables, the safe working load recommended by the manufacturer for
specific, identifiable products shall be
followed, provided that a safety factor
of not less than 5 is maintained.
(2) Protruding ends of strands in
splices on slings and bridles shall be
covered or blunted.
(3) Wire rope shall not be secured by
knots, except on haul back lines on
scrapers.
(4) The following limitations shall
apply to the use of wire rope:
(i) An eye splice made in any wire
rope shall have not less than three full
tucks. However, this requirement shall
not operate to preclude the use of another form of splice or connection
which can be shown to be as efficient
and which is not otherwise prohibited.
(ii) Except for eye splices in the ends
of wires and for endless rope slings,
each wire rope used in hoisting or lowering, or in pulling loads, shall consist
of one continuous piece without knot
or splice.
(iii) Eyes in wire rope bridles, slings,
or bull wires shall not be formed by
wire rope clips or knots.
(iv) Wire rope shall not be used if, in
any length of eight diameters, the
total number of visible broken wires
exceeds 10 percent of the total number
of wires, or if the rope shows other
signs of excessive wear, corrosion, or
defect.
(5) When U-bolt wire rope clips are
used to form eyes, Table H–20 shall be
used to determine the number and
spacing of clips.
(i) When used for eye splices, the Ubolt shall be applied so that the ‘‘U’’
section is in contact with the dead end
of the rope.
(6) Slings shall not be shortened with
knots or bolts or other makeshift devices.
(7) Sling legs shall not be kinked.
(8) Slings used in a basket hitch shall
have the loads balanced to prevent slippage.
(9) Slings shall be padded or protected from the sharp edges of their
loads.
(10) Hands or fingers shall not be
placed between the sling and its load
while the sling is being tightened
around the load.
(11) Shock loading is prohibited.
(12) A sling shall not be pulled from
under a load when the load is resting
on the sling.
(13) Minimum sling lengths. (i) Cable
laid and 6 × 19 and 6 × 37 slings shall
have a minimum clear length of wire
rope 10 times the component rope diameter between splices, sleeves or end
fittings.
(ii) Braided slings shall have a minimum clear length of wire rope 40 times
the component rope diameter between
the loops or end fittings.
(iii) Cable laid grommets, strand laid
grommets and endless slings shall have
a minimum circumferential length of
96 times their body diameter.
(14) Safe operating temperatures. Fiber
core wire rope slings of all grades shall
be permanently removed from service
if they are exposed to temperatures in
excess of 200 °F (93.33 °C). When
nonfiber core wire rope slings of any
grade are used at temperatures above
400 °F (204.44 °C) or below minus 60 °F
(15.55 °C), recommendations of the sling
manufacturer regarding use at that
temperature shall be followed.
(15) End attachments. (i) Welding of
end attachments, except covers to
thimbles, shall be performed prior to
the assembly of the sling.
(ii) All welded end attachments shall
not be used unless proof tested by the
manufacturer or equivalent entity at
twice their rated capacity prior to initial use. The employer shall retain a
certificate of the proof test, and make
it available for examination.
(d) Natural rope, and synthetic fiber—
(1) General. When using natural or synthetic fiber rope slings, Tables H–15, 16,

(i) In manila rope, eye splices shall
contain at least three full tucks, and
short splices shall contain at least six
full tucks (three on each side of the
centerline of the splice).
(ii) In layed synthetic fiber rope, eye
splices shall contain at least four full
tucks, and short splices shall contain
at least eight full tucks (four on each
side of the centerline of the splice).
(iii) Strand end tails shall not be
trimmed short (flush with the surface
of the rope) immediately adjacent to
the full tucks. This precaution applies
to both eye and short splices and all
types of fiber rope. For fiber ropes
under 1-inch diameter, the tails shall
project at least six rope diameters beyond the last full tuck. For fiber ropes
1-inch diameter and larger, the tails
shall project at least 6 inches beyond
the last full tuck. In applications
where the projecting tails may be objectionable, the tails 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).
(iv) For all eye splices, the eye shall
be sufficiently large to provide an included angle of not greater than 60° at
the splice when the eye is placed over
the load or support.
(v) Knots shall not be used in lieu of
splices.
(3) 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 (¥28.88 °C) to plus 180 °F (82.2 °C)
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.
(4) 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:
(i) 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.
(ii) In synthetic fiber rope, eye
splices shall consist of at least four full
§ 1926.251
tucks, and short splices shall consist of
at least eight full tucks, four on each
side of the center line.
(iii) 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 1 inch (2.54 cm) in
diameter, the tail shall project at least
six rope diameters beyond the last full
tuck. For fiber rope 1 inch (2.54 cm) in
diameter and larger, the tail shall
project at least 6 inches (15.24 cm) 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).
(iv) Fiber rope slings shall have a
minimum clear length of rope between
eye splices equal to 10 times the rope
diameter.
(v) Knots shall not be used in lieu of
splices.
(vi) Clamps not designed specifically
for fiber ropes shall not be used for
splicing.
(vii) 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.
(5) End attachments. Fiber rope slings
shall not be used if end attachments in
contact with the rope have sharp edges
or projections.
(6) Removal from service. Natural and
synthetic fiber rope slings shall be immediately removed from service if any
of the following conditions are present:
(i) Abnormal wear.
(ii) Powdered fiber between strands.
(iii) Broken or cut fibers.
(iv) Variations in the size or roundness of strands.
(v) Discoloration or rotting.
(vi) Distortion of hardware in the
sling.
(e) Synthetic webbing (nylon, polyester,
and polypropylene). (1) The employer
shall have each synthetic web sling
marked or coded to show:
(i) Name or trademark of manufacturer.
