1. Inspection Of Slings
McCoy Drilling & Completions strongly recommends the following practices:
Acompleteinspectionofnewload-bearingdevicesandattachmentsshallbeperformedbyaqualified,designatedpersonprior
toinitialuse.Eachlinkandcomponentshallbeexaminedindividually,takingcaretoexposeandexamineallsurfacesincluding
theinnerlinksurface.Theslingshallbeexaminedforconditionssuchasthoselistedintheremovalcriteriabelow.Inaddition,
dailyinspectionofslings,fasteningsandattachmentsshallbeperformedbyadesignatedperson.Ifdamageordefectsarefound
ateitherinspection,thedamagedordefectivecomponentshallbequarantinedfromserviceuntilitcanbeproperlyrepairedor
replaced.
RemovalCriteria:
Aload-bearingdeviceshallberemovedfromserviceifconditionssuchasthefollowingarepresent:
• Missingorillegibleslingidentification.
• Cracksorbreaks
• Evidenceoftamperingisseen-slingtaghasbeenmodifiedorobscured,ortamper-proofnutsaremissing.
• Signsofimpactonload-bearingcomponents,includingspreaderbars,liftinglugs,rigidslings&rigidslingweldments,and
legs&legmounts.
• Brokenordamagedwelds.
• Excessivewear,nicks,orgouges.Refertothechartbelowtoensureminimumthicknessonchainlinkssuppliedisnotbe

• Otherconditions,includingvisibledamage,thatcausedoubtastothecontinueduseofthesling.
Inspect all lugs and fixing points for signs of elongation and/or bending, or for material build-up around the hole. Repair or
replace components that appear distorted. Ensure all hardware is tight and in good condition. Replace missing hardware if
necessary.Allhardwaremustbefreeofrustandcorrosion.
Additionalinspectionsshallbeperformedduringslingusewhereserviceconditionswarrant.Periodicinspectionintervalsshall
notexceedoneyear.Thefrequencyofperiodicinspectionsshouldbebasedon:
• Frequencyofuseoftheload-bearingdevice.
• Severityofserviceconditions
• Natureofliftsbeingmade
• Experiencegainedontheservicelifeofload-bearingdevicesusedinsimilarcircumstances.
Guidelinesfortheintervalare:
• NormalService-yearly
• SevereService-monthlytoquarterly
• SpecialService-asrecommendedbyaqualifiedperson

IF MECHANICAL DAMAGE IS SEEN OR SUSPECTED ON A LOAD-BEARING
DEVICE, OR IF THE LOAD-BEARING DEVICE HAS BEEN OVERLOADED, IT MUST

2. Proper Use Of Load-Bearing Devices
Wheneveranyload-bearingdeviceisused,thefollowingpracticesshallbeobserved.
• Load-bearingdevicesthataredamagedordefectiveshallnotbeused.
• Slingsshallnotbeshortenedwithknotsorboltsorothermakeshiftdevices.
• Slinglegsshallnotbekinked.
• Load-bearingdevicesshallnotbeloadedinexcessoftheirratedcapacities.
• Slingsshallbesecurelyattachedtotheirload.
• Load-bearingdevicesshallbeprotectedfromsnagging,andshallnotbefurtherobstructedbyanyobject.
• Suspendedloadsshallbekeptclearofallobstruction.
• Allemployeesshallbekeptclearofloadsabouttobeliftedandofsuspendedloads.
• Handsorfingersshallnotbeplacedbetweentheslinganditsloadwhiletheslingisbeingtightenedaroundtheload.
• Shockloadingisprohibited.
• Donotstanddirectlyunderaloadduringlifting.
3. Storage Of Load-Bearing Devices
Properstorageof out-of-service load bearing devices isimportantto ensure full integrity of thedeviceonce it is returned to
service.Farrrecommendsobservingthefollowingpractices.
• Wipeoffallexcessgrease.Useasolvent-basedcleaneronragstowipeallexternalsurfacestoremoveresidualgrease
orhydraulicfluid.Oncetheoutsidesurfaceshavebeende-greased,wipeallexternalsurfaceswithcleanwatertoremove
residualsolvent.
• Farrrecommendsthatananti-corrosiveagentsuchasTectyl®506beappliedtoallexternalsurfaces.Refertomanufac-
turerdatasheetsforproperapplicationandsafetyinformation.Allowtheanti-corrosivecoatingampletimetodry-referto
manufacturerdatasheetsfordryingtimesatroomtemperature.
• Storeinaclean,drylocation.Whenreturningtoservice,notethatafullinspectionofthedevicemustbeperformed.
