Metal mesh slings --

1910.184(g)(1)

Sling marking. Each metal mesh sling shall have permanently affixed to it a durable marking that states the rated capacity for vertical basket hitch and choker hitch loadings.

1910.184(g)(2)

Handles. Handles shall have a rated capacity at least equal to the metal fabric and exhibit no deformation after proof testing.

1910.184(g)(3)

Attachments of handles to fabric. The fabric and handles shall be joined so that:

1910.184(g)(3)(i)

The rated capacity of the sling is not reduced.

1910.184(g)(3)(ii)

The load is evenly distributed across the width of the fabric.

1910.184(g)(5)

Sling testing. All new and repaired metal mesh slings, including handles, shall not be used unless proof tested by the manufacturer or equivalent entity at a minimum of 1 1/2 times their rated capacity. Elastomer impregnated slings shall be proof tested before coating.

..1910.184(g)(6)

1910.184(g)(6)

Proper use of metal mesh slings. Metal mesh slings shall not be used to lift loads in excess of their rated capacities as prescribed in Table N-184-15. Slings not included in this table shall be used only in accordance with the manufacturer's recommendations.

1910.184(g)(7)

Safe operating temperatures. Metal mesh slings which are not impregnated with elastomers may be used in a temperature range from minus 20 deg. F to plus 550 deg. F without decreasing the working load limit. Metal mesh slings impregnated with polyvinyl chloride or neoprene may be used only in a temperature range from zero degrees to plus 200 deg. F. For operations outside these temperature ranges or for metal mesh slings impregnated with other materials, the sling manufacturer's recommendations shall be followed.

1910.184(g)(8)

Repairs.

1910.184(g)(8)(i)

Metal mesh slings which are repaired shall not be used unless repaired by a metal mesh sling manufacturer or an equivalent entity.

1910.184(g)(8)(ii)

Once repaired, each sling shall be permanently marked or tagged, or a written record maintained, to indicate the date and nature of the repairs and the person or organization that performed the repairs. Records of repairs shall be made available for examination.

1910.184(g)(9)

Removal from service. Metal mesh slings shall be immediately removed from service if any of the following conditions are present:

..1910.184(g)(9)(i)

1910.184(g)(9)(i)

A broken weld or broken brazed joint along the sling edge.

See Figs. N-184-4 and N-184-5 for sling configuration descriptions.

1910.184(h)(2)

Safe operating temperatures. Natural and synthetic fiber rope slings, except for wet frozen slings, may be used in a temperature range from minus 20 deg. F to plus 180 deg. 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.

1910.184(h)(3)

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:

1910.184(h)(3)(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.

1910.184(h)(3)(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.

..1910.184(h)(3)(iii)

1910.184(h)(3)(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 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).

1910.184(h)(3)(iv)

Fiber rope slings shall have a minimum clear length of rope between eye splices equal to 10 times the rope diameter.

1910.184(h)(3)(v)

Knots shall not be used in lieu of splices.

1910.184(h)(3)(vi)

Clamps not designed specifically for fiber ropes shall not be used for splicing.

1910.184(h)(3)(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.

1910.184(h)(4)

End attachments. Fiber rope slings shall not be used if end attachments in contact with the rope have sharp edges or projections.

1910.184(h)(5)

Removal from service. Natural and synthetic fiber rope slings shall be immediately removed from service if any of the following conditions are present:

1910.184(h)(5)(i)

Abnormal wear.

1910.184(h)(5)(ii)

Powdered fiber between strands.

..1910.184(h)(5)(iii)

1910.184(h)(5)(iii)

Broken or cut fibers.

1910.184(h)(5)(iv)

Variations in the size or roundness of strands.

1910.184(h)(5)(v)

Discoloration or rotting.

1910.184(h)(5)(vi)

Distortion of hardware in the sling.

1910.184(h)(6)

Repairs. Only fiber rope slings made from new rope shall be used. Use of repaired or reconditioned fiber rope slings is prohibited.

1910.184(i)

Synthetic web slings --

1910.184(i)(1)

Sling identification. Each sling shall be marked or coded to show the rated capacities for each type of hitch and type of synthetic web material.

1910.184(i)(2)

Webbing. Synthetic webbing shall be of uniform thickness and width and selvage edges shall not be split from the webbing's width.

1910.184(i)(3)

Fittings. Fittings shall be:

1910.184(i)(3)(i)

Of a minimum breaking strength equal to that of the sling; and

1910.184(i)(3)(ii)

Free of all sharp edges that could in any way damage the webbing.

..1910.184(i)(4)

1910.184(i)(4)

Attachment of end fittings to webbing and formation of eyes. Stitching shall be the only method used to attach end fittings to webbing and to form eyes. The thread shall be in an even pattern and contain a sufficient number of stitches to develop the full breaking strength of the sling.

1910.184(i)(5)

Sling use. Synthetic web slings illustrated in Fig. N-184-6 shall not be used with loads in excess of the rated capacities specified in Tables N-184-20 through N-184-22. Slings not included in these tables shall be used only in accordance with the manufacturer's recommendations.

1910.184(i)(6)

Environmental conditions. When synthetic web slings are used, the following precautions shall be taken:

1910.184(i)(6)(i)

Nylon web slings shall not be used where fumes, vapors, sprays, mists or liquids of acids or phenolics are present.

1910.184(i)(6)(ii)

Polyester and polypropylene web slings shall not be used where fumes, vapors, sprays, mists or liquids of caustics are present.

1910.184(i)(6)(iii)

Web slings with aluminum fittings shall not be used where fumes, vapors, sprays, mists or liquids of caustics are present.

Act now! It is essential that you inquire about your case as soon as possible. Litigation may be the only way to receive the damages to which you may be entitled, such as medical and health care bills, lost or diminished wages, and financial compensation to family in the case of death. Your individual state's law may limit your time to bring a legal claim to protect your rights. You need to have your construction accidents claim evaluated immediately!
