Ringkasan Jawaban Singkat

Exclusion Zone adalah area di sekitar operating equipment dimana entry dilarang untuk mencegah struck-by atau crushing incidents.Kenapa Exclusion Zone Penting:Heavy equipment punya blind spots - operator tidak bisa see all directionSwinging/rotating equipment (excavator, crane) create dynamic hazard zoneBacking equipment - highest risk untuk pedestrian collisionExclusion Zone Distances:General Equipment:Stationary: 3 meter dari edgeMoving: 5 meter dari all sidesBacking: 10 meter dari rearSpecific Equipment:Excavator: Radius of boom swing + 2 meterCrane: Radius of load swing + 3 meterBulldozer: 5 meter all sides saat operatingDump Truck: 10 meter saat dumping (falling material)How to Establish Exclusion Zone:1. Physical BarriersHard barricade: Safety fence, concrete barrier (permanent work)Soft barricade: Safety tape, traffic cone (temporary)Signage: "DANGER - Keep Out" signs visible2. Ground MarkingSpray paint atau chalk line untuk demarcate zoneColor code: Red = No entry, Yellow = Caution3. CommunicationToolbox talk inform all workersSignage di entry pointsOperator Responsibilities:Before starting: Ensure exclusion zone established dan clearDuring operation:Continuous 360° awarenessSound horn before movementSTOP immediately if someone enters zoneDo not rely solely on spotter - operator still responsibleIf zone breached:Stop operationUse horn/verbal warning untuk evacuate personDo not resume until clearWorker Responsibilities:NEVER enter exclusion zone without authorizationIf must enter: Eye contact dengan operator, wait for signal, use spotterSpecial Situations:Confined Site (Limited Space):Use banksman/spotter mandatoryProceed at walking paceConsider sequential work - stop equipment saat workers closeExclusion zone violations cause 50% struck-by fatalities - enforce strictly!
