<strong>DOE</strong>-<strong>STD</strong>-I090-<strong>96</strong> (Rev-I)notified <strong>and</strong> will approve the requirement beforethe lift is made.c. Use onlypersonnel platforms that arespecificallydesigned <strong>and</strong> constructed for thepurpose of suspending personnel according to thefollowing:1. The personnel platform shall bedesigned by a qualified person competent instructural design, <strong>and</strong> all welding ofthe platformshall be performed by a qualified welder familiarwith the weld grades, types, <strong>and</strong> material specifiedin the design.2. The platform shall be limited tocarrying six persons.3. The personnel platform <strong>and</strong> riggingshall be capable ofsupporting, without failure, atleast five time the maximum intended load.4. The platform shall bear a platespecifying its empty weight <strong>and</strong> the maximumnumber ofpersons <strong>and</strong> weight for which it israted.5. The platform shall have perimeterprotection consisting ofa top rail approximately45 in. (115 em) high, a toeboard at least 4 in.(10 cm) high, <strong>and</strong> a midrail approximatelyhalf-way between the top rail <strong>and</strong> the toeboard.6. A grab rail shall beprovided inside thepersonnel platform to minimize h<strong>and</strong> exposure.7. The sides ofthe platform shall beenclosed from the toeboard to the midrail withsolid construction or exp<strong>and</strong>ed metal havingopenings no greater than 1/2 in. (1.27 em).8. Ifaccess doors are installed, they shallopen only to the interior ofthe platform. Accessdoors shall be equipped with a device to restrainthem from opening unintentionally.9. The personnel platform shall haveoverhead protection when there is an overheadhazard.10. Sufficient headroom shall be providedto allow employees to st<strong>and</strong> upright in theplatform.11. Rough edges exposed to contact byemployees shall be surfaced (ground smooth) toprevent injury.12. The platform shall be easilyidentifiable byhigh-visibility color or marking.13. All welding procedures <strong>and</strong> weldingoperator qualifications shall be in accordance withANSIJAWS Dl.1 when welding is to beperformed on load-sustaining members. Wherespecial steels or other materials are used, themanufacturer shall provide welding procedures.Welds shall be inspected by a qualified inspector.14. When being supported by a crane, theplatform shall be attached to the hoist rope by ahook ofa type that canbe closed <strong>and</strong> locked,eliminating the hook throat opening.Alternatively, an alloy steel anchor shackle with abolt, nut, <strong>and</strong> retaining pin may beused.15. All eyes in wire-rope slings shall befabricated with thimbles, <strong>and</strong> rigging accessoriesfor attaching the personnel platform to hoist linesshall not be used for any other purpose when nothoisting personnel.16. The suspension system shall minimizeinclination of the personnel platform due to themovement ofpersonnel on the personnel platform.d. At each newjob site (<strong>and</strong> at least annUally)prior to hoisting personnel, the personnelplatform, rigging, <strong>and</strong> hook block shall beproof-tested by a qualified inspector to twice thepersonnel platform's rated capacitybyholding itsuspended for 5 min with the test load suitablydistributed on the personnel platform. Afterproof-testing, any deficiencies revealed byinspection, or by the prooftest, shall be corrected,<strong>and</strong> another prooftest conducted. Anymodification to the personnel platform or riggingshall require retesting.e. Prior to the trial lift, a meeting shall be heldwith the designated leader, qualified operator,signaler, persons to be lifted, <strong>and</strong> the personresponsible for overall worksite safety to plan <strong>and</strong>review procedures to be followed. Procedures forentering <strong>and</strong> leaving the personnel platform orother device <strong>and</strong> the points at which persons willenter <strong>and</strong> leave the device shall be reviewed.f. Prior to lifting personnel <strong>and</strong> after the prooftest, the qualified operator <strong>and</strong> signaler shallconduct a trial lift with the personnel platformloaded to at least the anticipated load.g. The trial lift shall be made from ground level(or any other location where employees will enter15-31Chapter 15Construction <strong>Hoisting</strong> <strong>and</strong> <strong>Rigging</strong>Equipment Requirements
