The operator shall recognize signals onlyfrom the designated signaler. Obey a STOPsignal no matter who gives it.10.5.4 Size of Loada. Since the load rating for forklifts may bebased on stability or hydraulic or structuralcompetence, do not exceed the rated capacity inoperational application.b. Do not load forklifts beyond rated capacity.c. The designated person shall ensure that theweight ofa load approaching the rated capacity(combination ofweight <strong>and</strong> location ofthe centerofgravity) has been determined within -10percent, +0 percent before it is lifted.10.5.5 Moving the Loada. The nature ofthe terrain <strong>and</strong> the surface onwhich the truck is to operate are very importantfactors in the stability of the load-truck system.The designated person shall ensure that a propertruck has been selected to operate on the surfaceavailable. In general, small, three-wheeled trucksshould operate on smooth, hard surfaces only <strong>and</strong>are not suitable for outdoor workb. The designated person shall ensure that theload is well secured <strong>and</strong> properly balanced beforeit is lifted.c. During hoisting, ensure that:1.load.There is no sudden acceleration ofthe2. The load does not contact anyobstruction.10.5.6 Ordinary Liftsa. The requirements of all precedingparagraphs in Section 10.5, "Operation," shallalso apply to ordinary lifts.b. An appointed person shall classify each liftinto one ofthe <strong>DOE</strong> categories (ordinary, criticalorpreengineered production) before the lift isplanned.c. <strong>Hoisting</strong> <strong>and</strong> rigging operations for ordinarylifts require a designated leader who shall bepresent at the lift site during the entire liftingoperation. Ifthe lift is being made by only oneperson, that person assumes all responsibilities ofthe designated leader.d. Leadership designation may be by writteninstructions, specific verbal instructions for theparticular job, or clearly delmed responsibilitieswithin the crew's organizational structure.e.The designated leader's responsibility shallinclude the following:1. Ensure that personnel involvedunderst<strong>and</strong> how the lift is to be made.2. Ensure that the weight ofthe load isdetermined, that proper equipment <strong>and</strong> accessoriesare selected, <strong>and</strong> that rated capacity is notexceeded.3. Survey the lift site for hazardous!unsafe conditions.4. Ensure that equipment is properly setup <strong>and</strong> positioned.5. Ensure that a signaler is assigned, ifrequired, <strong>and</strong> is identified to the operator.6. Direct the lifting operation to ensurethat the job is done safely <strong>and</strong> efficiently.7. Stop the job when any potentiallyunsafe condition is recognized.8. Direct operations ifan accident orinjury occurs.10.5.7 Critical LiftsSee Chapter 2, "Critical Lifts," for critical-liftrequirements.10-11Chapter 10Forklift Trucks
