consist of at least six full tucks, three on each side of the splice center line.
1926.251(d)(4)(ii) 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.
..1926.251(d)(4)(iii)
1926.251(d)(4)(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 lest two additional tucks (which will require a tail length of approximately six rope diameters
beyond the last full tuck).
1926.251(d)(4)(iv) Fiber rope slings shall have a minimum clear length of rope between eye splices equal to 10
times the rope diameter.
1926.251(d)(4)(v) Knots shall not be used in lieu of splices.
1926.251(d)(4)(vi) Clamps not designed specifically for fiber ropes shall not be used for splicing.
1926.251(d)(4)(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.
1926.251(d)(5) "End attachments." Fiber rope slings shall not be used if end attachments in contact with the rope
have sharp edges or projections.
1926.251(d)(6) "Removal from service." Natural and synthetic fiber rope slings shall be immediately removed from
service if any of the following conditions are present:
1926.251(d)(6)(i) Abnormal wear.
