DOE-STD-I090-96 (Rev-I)j. Despite their inherent toughness,synthetic-web slings canbe cut byrepeated usearound sharp-cornered objects. They eventuallyshow signs of abrasion when they are repeatedlyused to hoist rough-surfaced products. There are,however, protective devices offered by most slingmanufacturers that minimize these effects (seeFigure 11-19). Other protective devices include:1. Buffer strips ofleather, nylon, or othermaterials that are sewn on the body ofa slingprotect against wear. Leather pads are the mostresistant to wear and cutting, but are subject toweathering and gradual deterioration. They arenot recommended in lengths over 6 ft due to thedifferent stretching characteristics ofleather andwebbing. On the other hand, nylon-web wearpads are more resistant to weathering, oils, grease,and most alkalis; and they stretch in the same ratioas the sling body.2. Edgeguards consist ofstrips ofwebbing or leather sewn around each edge ofthesling. This is necessary for certain applicationswhere the sling edges are subject to damage.3. Sleeve- or sliding-tube-type wear padsare available for slings used to handle materialhaving sharp edges. They can be positioned onthe sling where required, do not move when thesling stretches, adjust to the load, and cover bothsides ofthe sling.4. Reinforcing strips that double or triplethe eye's thickness and greatly increase its life andsafety can be sewn into the sling eyes.5. Coatings can be applied to provideadded resistance to abrasion and chemicaldamage. These treatments also increase thecoefficient offriction, affording a better grip whenloads with slippery surfaces are to behandled.These coatings can bebrightly colored for safetyor load-rating purposes.6. Cotton-faced nylon webbing can beused for hoisting rough-surfaced material.k. The synthetic-web sling capacities listed inTables 11-14 and 11-15 are approximate only andare based on nylon webbing having breakingstrengths between 6,000 and 9,000 lb/in. ofwebbing width. The capacities are also based on a5:1 design factor and assume that the end fittingsare of adequate strength.1. Although safe working loads for bridlehitches in the choker or double-basketconfiguration are provided, they should be usedonly with extreme caution because, as the slingangle decreases, one edge ofthe web will take allthe load, producing a risk oftearing (see Figure11-20).m. Synthetic-web slings, other than thosedescribed in this section [Le., polyester round andkevlar fiber (yam) slings], shall be used inaccordance with the sling manufacturer'srecommendation.n. Conventional three-strand natural orsynthetic fiber rope slings are NOT recommendedfor lifting service and should be used only ifconventional sling types are not suitable for aunique application. The requirements ofASMEB30.9 ("Slings"), Section 9-4, and 29 CFR191O.184(h) shall be followed.CAUTION: Tiedown and/or ratchet strap shallnot be used as synthetic-web slings. Onlysynthetic-web slings constructed from webbingapproved for sling construction by themanufacturer or other qualified person shall beused at DOE locations.11.3.5.1 Inspectionsa. Users ofsynthetic-web sling shall visuallyinspect all slings before each use.b. Annual inspection shall be made by aqualified inspector, and inspection records shall bekept on file and readily available.c. When it is necessary to use a nylon orpolyester sling in a radiation area, the responsiblemanager shall ensure that radiation exposure doesnot exceed 100,000 rad during the life ofthe sling.Chapter 11Wire Rope and Slings 11-32
