Materials Handling,Storage,Use,and Disposal1Office of Training&EducationOverview-Handling and Storing Materials Involves diverse operations:Manual material handlingCarrying bags or materialsUnpacking materialsMaterial handling via machineForkliftCraneRigging Stacking or storing drums,barrels,kegs,lumber,loose bricks or other materials2Office of Training&EducationInjuriesLifting objects is a major cause of back injuries in the work placeImproper storing and handling of material and equipment can cause struck by and crushed by injuries 3Office of Training&EducationHazardsImproper manual lifting or carrying loads that are too large or heavyBeing struck by materials or being caught in pinch points Crushed by machines,falling materials or improperly stored materialsIncorrectly cutting ties or securing devices4Office of Training&EducationManual HandlingSeek help:When a load is too bulky to properly grasp or lift When you cant see around or over the load When you cant safely handle the loadAttach handles to loads to reduce the chances of getting fingers smashed.5Office of Training&EducationSafe LiftingBreak load into partsGet help with heavy or bulky itemsLift with legs,keep back straight,do not twistUse handling aids-such as steps,trestles,shoulder pads,handles,and wheelsAvoid lifting above shoulder level6Office of Training&EducationSafe Lifting TrainingWhat should be taught:How to lift safelyHow to avoid unnecessary physical stress and strainWhat you can comfortably handle without undue strainProper use of equipmentRecognizing potential hazards and how to prevent/correct them7Office of Training&EducationPersonal Protective EquipmentFor loads with sharp or rough edges,wear gloves or otherhand and forearm protection When loads are heavy or bulky,wear steel-toed safety shoes toprevent foot injuries if the loadis dropped8Office of Training&EducationMaterials Handling EquipmentEmployees must betrained in the properuse and limitations of the equipment they operate This includes knowing how to effectively useequipment such asforklifts,cranes,and slings9Office of Training&EducationForkliftsCenter the load on the forks and as close to the mast as possible to minimize the potential for the truck tipping or load falling Overloading a lift truck makes it hard to control and could make it tip overPlace the load at the lowest position for travelingDont place extra weight on the rear of a counterbalanced forklift to allow an overload10Office of Training&EducationOperating a Forklift SafelyKeep arms and legs inside the truckHandle only stable loadsKeep speed low-you may have to stopBe careful when making sharp turnswith a raised loadIf a load blocks your view,travel in reverseNo riders,unless theres an approved seatDont drive with forks raisedWear safety belts or other restraint devices11Office of Training&Education Powered Industrial Truck Training Truck-related topics Workplace-related topics Standard requirements Trainees must be supervised by a competent person and not endanger others Formal instruction Practical training Evaluation of performance12Office of Training&EducationDock Boards(Bridge plates)Dock boards must have handholds,orother effective meansfor safe handling.13Office of Training&EducationEarthmoving EquipmentScrapers,loaders,crawler or wheel tractors,bulldozers,off-highway

in the cabFrequently inspectNever lift peopleCheck overhead power linesEnsure area of travel is clear15Office of Training&EducationRigging Equipment SlingsTypes of slings covered are those made from alloy steel chain,wire rope,metal mesh,natural or synthetic fiber rope,and synthetic web.ChainWire ropeMetal meshSynthetic16Office of Training&EducationSling InspectionInspect slings:Each day before use Where service conditions warrantRemove them from service ifdamaged or defective17Office of Training&EducationRemove From ServiceImmediately remove damaged or defective slings from service18Office

these are present:Acid or caustic burnsMelting or charring of any part Snags,punctures,tears or cutsBroken or worn stitchesDistortion of fittingsSynthetic Web Slings-Remove from ServiceHeat Damage33Office of Training&EducationStoring MaterialsSecure materials stored in tiers by stacking,racking,blocking,or interlocking to prevent them from fallingPost safe load limits of floorsKeep aisles and passageways clear34Office of Training&EducationStoring MaterialsDont store noncompatible materials togetherIn buildings under construction,dont place stored materials within 6 feet of a hoistway or floor opening35Office of Training&EducationEmployees who work on stored materials in silos,hoppers,or tanks,must be equipped with lifelines and harnessesFall Protection36Office of Training&EducationStack bricks in a manner that will keep them from fallingDo not stack them more than 7 feet highTaper back a loose brick stack after it is 4 feet highBrick Storage37Office of Training&EducationLumberRemove nails before stackingStack on sillsStack lumber so that it is stable and self supporting38Office of Training&EducationHousekeepingKeep storage areas free from accumulated materials that cause tripping,fires,or explosions,or that may contribute to harboring rats and pests 39Office of Training&EducationDisposal of Waste MaterialsUse an enclosed chute when you drop material more than 20 feet outside of a buildingIf you drop debris through holes in the floor without chutes,enclose the drop area with barricades40Office of Training&EducationDisposal of Scrap and Flammable MaterialsRemove all scrap lumber,waste material,and rubbish from the immediate work area as work progressesKeep all solvent waste,oily rags,and flammable liquids in fire resistant covered containers until removed from worksite41Office of Training&EducationDisposal of Demolition Materials Removal of materials through floor openingsOpenings must be less than 25 percent of the whole floorFloors weakened or made unsafe by demolition must be shored so they can safely carry the demolition load42Office of Training&EducationSummaryManually handling materialsWhen lifting objects,lift with your legs,keep your back straight,do not twist,and use handling aids Using cranes,forklifts,and slings to move materialsWatch for potential struck by and crushed by dangersFor slings,check their load capacity,inspect them,and remove them from service when they display signs of stress or wearAlso-Keep work areas free from debris and materialsStore materials safely to avoid struck by/crushed by hazards43Office of Training&Education1、有时候读书是一种巧妙地避开思考的方法。3月-233月-23Monday,March 6,20232、阅读一切好书如同和过去最杰出的人谈话。23:22:4723:22:4723:223/6/2023 11:22:47
