<strong>DOE</strong>-<strong>STD</strong>-I090-<strong>96</strong> (Rev-I)4.1 GENERALa. This chapter specifies the operation, design,testing, <strong>and</strong> inspection requirements for the use ofpersonnel lift platforms or baskets suspendedfrom mobile or overhead cranes. This chapterimplements the requirements ofASME B30.5,"Mobile Cranes."b. The manager specifically responsible for theoverall work function to be performed shalldetermine that the erection, use, <strong>and</strong> dismantlingofconventional means ofreaching the work site(i.e., scaffold, ladder, stairway, aerial lift, orelevating work platform) would be morehazardous or is not possible because of structuraldesign or worksite conditions.c. For each personnel lifting procedure, themanager responsible for the task shall authorizethe use ofa crane-suspended work platform <strong>and</strong>attest to the need for the operation through awritten justification attesting to that need. Astatement describing the operation <strong>and</strong> its timeframe shall be included. The statement, afterbeing approved by the authorizer, shall be retainedat the job site.d. These special procedures shall be followedwhen lifting personnel:1. The crane shall be inspected dailyprior to lifting personnel, in accordance with therequirements for frequent inspections for the typeofequipment being used.2. The lifting <strong>and</strong> supporting shall bemade under controlled conditions <strong>and</strong> under thedirection ofa designated leader. A qualifiedsignaler shall be appointed.3. Prior to use each working shift, thepersonnel lift platform <strong>and</strong> rigging shall beinspected.4. At each newjob site (<strong>and</strong> at leastannually) prior to hoisting personnel, thepersonnel platform, rigging, <strong>and</strong> hook block shallbe proof-tested by a qualified inspector to twicethe personnel platform's rated capacity by holdingit suspended for 5 min with the test load suitablydistributed on the personnel platform. Mterproof-testing, any deficiencies revealed byinspection, or by the prooftest, shall be corrected<strong>and</strong> another proof-test conducted. Anymodification to the personnel platform or riggingshall require retesting.5. Prior to lifting personnel <strong>and</strong> after theprooftest, the qualified operator <strong>and</strong> signaler shallconduct a trial lift with the personnel platformloaded to at least the maximum anticipated load.The trial lift shall be made from ground level (orany other location where employees will enter theplatform) to each location at which the platform isto behoisted <strong>and</strong> positioned. The designatedleader <strong>and</strong> the operator shall determine that:i. Crane (mobile) footing isadequate.ii.iii.iv.System controls <strong>and</strong> safetydevices are activated <strong>and</strong>functioning properly.No interferences exist.Configurations necessary toreach work locations will allowthe crane to remain under50 percent ofrated capacity.NOTE: Materials <strong>and</strong> tools to be used during theactual lift, ifsecured to prevent displacement, canbe in the platform for the test lift.NOTE: A single trial lift may be performed for alllocations to be reached from a single setupposition.6. The trial lift shall be repeated prior tohoisting employees whenever:i. The crane (mobile) travels or ismoved <strong>and</strong> set up in a newlocation or returned to apreviously used location.ii.The lift route is changed, unlessthe operator determines that thesafety ofthe hoisted personnel isnot affected.7. A visual inspection ofthe crane,rigging, <strong>and</strong> personnel platform shall be conductedby a qualified inspector immediately after the triallift, prior to lifting personnel.
