Rigging requires careful evaluation because of the wide variety of safety factors which must be considered in each case. These factors include, but are not limited to: size and type of sling, the method of fastening, sheaves, sprockets, and drums, condition of equipment or material, size and shape of load, type of attachment, the lifting environment, weather and atmospheric conditions. Some serious hazards result from overloading, improper hitching or slinging which allow the load to drop or slip; obstructing free movement of loaded sling; and using equipment for a purpose not intended or designed. 1.2 GENERAL REQUIREMENTS FOR RIGGING 1.2.1 SAFE USE OF SLINGS 1.2.1.1 Safe Operating Practice: Slings that are damaged or defective should not be used. Slings should not be shortened with knots or bolts or other makeshift devices. Sling legs should not be kinked. Slings should not be loaded in excess of their rated capacities. Slings used in a basket hitch should have the loads balanced to prevent slippage. Slings should be securely attached to their loads. Slings should be padded or protected from the sharp edges of their loads. Suspended loads should be kept clear of all obstructions. All personnel should be kept clear of loads about to be lifted and of suspended loads. Revised: 0 Page 1 of 14 Date: 06 June 2022

1 RIGGING PRACTICES
1.1 SECTION CONTENTSThis section provides basic rigging information for the safe use of slings. Rigging requires careful evaluation because of the wide variety of safety factors which must be considered in each case. These factors include, but are not limited to: size and type of sling, the method of fastening, sheaves, sprockets, and drums, condition of equipment or material, size and shape of load, type of attachment, the lifting environment, weather and atmospheric conditions.Some serious hazards result from overloading, improper hitching or slinging which allow the load to drop or slip; obstructing free movement of loaded sling; and using equipment for a purpose not intended or designed.
1.2 GENERAL REQUIREMENTS FOR RIGGING
1.2.1 SAFE USE OF SLINGS1.2.1.1 Safe Operating Practice: Slings that are damaged or defective should not be used. Slings should not be shortened with knots or bolts or other makeshift devices. Sling legs should not be kinked. Slings should not be loaded in excess of their rated capacities. Slings used in a basket hitch should have the loads balanced to prevent slippage. Slings should be securely attached to their loads. Slings should be padded or protected from the sharp edges of their loads. Suspended loads should be kept clear of all obstructions. All personnel should be kept clear of loads about to be lifted and of suspended loads. Hands or fingers should not be placed between the sling and its load while the sling is being
tightened around the load. Shock loading is prohibited. A sling should not be pulled from under a load when the load is resting on the sling. Slings should be stored where they will not be damaged by extreme heat, corrosion, being
run over, or being kinked.
1.2.2 TYPES OF SLINGSSlings are available in alloy steel chain, wire rope with fiber core or steel rope core, metal mesh, natural or synthetic fiber rope, or synthetic wedding. Slings should be used in accordance with manufacturer’s recommendations and regulatory requirements.

RIGGING RESPONSIBILITY PROCEDURE
1.2.3 RATED CAPACITY OF SLINGS
Care must be exercised when using tables and charts for slings. The units of measurements need to be noted in each case. Rated capacity may need to be reduced because of the configuration of attachment to load. Rated capacity may need to be reduced because of non-vertical load angel. Rated capacity may need to be reduced because of high or low operating temperatures. Rated capacity may need to be reduced because of end connection and splices. Rated capacity, where there is more than one leg, applies only where the load is distributed
evenly between legs.

Figure 4 Manila Rope and Tackle Table of Rated capacities in Lbs.
1. Tables are based on the use of new manila rope and tackle that is in good condition.2. If sisal rope is used, values in tables should be reduced by one third.3. Tackle values allow for one snatch block, snatching lead line to engine spool.4. When using more than one snatch block, add one extra part for each additional snatch
block in addition to the number of parts shown for the weight to lift.
