Materials Handling, Storage, Use, and Disposal Office of Training & Education 1 Overview -- Handling and Storing Materials Involves diverse operations: Manual material handling  Carrying bags or materials  Unpacking materials Material handling via machine  Forklift  Crane  Rigging Stacking or storing drums, barrels, kegs, lumber, loose bricks or other materials Office of Training & Education 2 Injuries Lifting objects is a major cause of back injuries in the work place Improper storing and handling of material and equipment can cause struck by and crushed by injuries Office of Training & Education 3 Hazards Improper manual lifting or carrying loads that are too large or heavy Being struck by materials or being caught in pinch points Crushed by machines, falling materials or improperly stored materials Incorrectly cutting ties or securing devices Office of Training & Education 4 Manual Handling Seek help: • When a load is too bulky to properly grasp or lift • When you can’t see around or over the load • When you can’t safely handle the load Attach handles to loads to reduce the chances of getting fingers smashed. Office of Training & Education 5 Safe Lifting Break load into parts Get help with heavy or bulky items Lift with legs, keep back straight, do not twist Use handling aids - such as steps, trestles, shoulder pads, handles, and wheels Avoid lifting above shoulder level Office of Training & Education 6 Safe Lifting Training What should be taught: • How to lift safely • How to avoid unnecessary physical stress and strain • What you can comfortably handle without undue strain • Proper use of equipment • Recognizing potential hazards and how to prevent / correct them Office of Training & Education 7 Personal Protective Equipment For loads with sharp or rough edges, wear gloves or other hand and forearm protection When loads are heavy or bulky, wear steel-toed safety shoes to prevent foot injuries if the load is dropped Office of Training & Education 8 Materials Handling Equipment Employees must be trained in the proper use and limitations of the equipment they operate This includes knowing how to effectively use equipment such as forklifts, cranes, and slings Office of Training & Education 9 Forklifts Center 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 over Place the load at the lowest position for traveling Don’t place extra weight on the rear of a counterbalanced forklift to allow an overload Office of Training & Education 10 Operating a Forklift Safely Keep arms and legs inside the truck Handle only stable loads Keep speed low - you may have to stop Be careful when making sharp turns with a raised load If a load blocks your view, travel in reverse No riders, unless there’s an approved seat Don’t drive with forks raised Wear safety belts or other restraint devices Office of Training & Education 11 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 performance Office of Training & Education 12 Dock Boards (Bridge plates) Dock boards must have handholds, or other effective means for safe handling. Office of Training & Education 13 Earthmoving Equipment Scrapers, loaders, crawler or wheel tractors, bulldozers, off-highway trucks, graders, tractors Provide seat belts Equipment with an obstructed rear view can’t be used in reverse unless the equipment has a signal alarm Office of Training & Education 14 Cranes Check the load chart in the cab Frequently inspect Never lift people Check overhead power lines Ensure area of travel is clear Office of Training & Education 15 Rigging Equipment Slings Types of slings covered are those made from alloy steel chain, wire rope, metal mesh, natural or synthetic fiber rope, and synthetic web. Chain Wire rope Metal mesh Office of Training & Education Synthetic 16 Sling Inspection Inspect slings:  Each day before use  Where service conditions warrant Remove them from service if damaged or defective Office of Training & Education 17 Remove From Service Immediately remove damaged or defective slings from service Office of Training & Education 18 Alloy Steel Chains Adapts to shape of the load Can damage by sudden shocks Best choice for hoisting very hot materials Must have an affixed tag stating size, grade, rated capacity, and sling manufacturer Office of Training & Education 19 Markings Alloy Steel Chain It must be marked with grade or manufacturer's mark Office of Training & Education 20 Alloy Steel Chain Attachments Rated Capacity Hooks, rings, oblong links, or other attachments, when used with alloy steel chains, must have a rated capacity at least equal to that of the chain Office of Training & Education 21 Unsuitable Alloy Steel Chain Attachments Right Wrong Job or shop hooks and links, or makeshift fasteners, formed from bolts, rods, etc., or other such attachments, can’t be used Office of Training & Education 22 Chain Wear When a chain shows excessive wear, or is cracked or pitted, remove it from service Non-alloy repair links can not be used Office of Training & Education 23 Wire Rope Slings Used to hoist materials Core Selection considerations:  strength  ability to bend without cracking  ability to withstand abrasive wear  ability to withstand abuse Office of Training & Education Wire Center Strand Wire rope 24 Wire Rope Slings Eye Splices Eye splices made in any wire rope must have at least three full tucks Office of Training & Education 25 Protruding Ends Cover or blunt protruding ends of strands Office of Training & Education 26 Wire Rope Clips When using U-bolt wire rope clips to form eyes, ensure the "U" section is in contact with the dead end of the rope Dead End This is the correct method Office of Training & Education 27 Lubrication Regularly lubricate ropes and chains Office of Training & Education 28 Wire Rope Slings Remove From Service If these happen, remove the wire rope sling from service Kinking Bird Caging Crushing Office of Training & Education 29 Synthetic Web Sling Markings Mark or code to show: • Name or trademark of manufacturer • Rated capacities for the type of hitch • Type of material Office of Training & Education 30 Synthetic Web Slings Fittings Fittings must be: • At least as strong as that of the sling • Free of sharp edges that could damage the webbing Office of Training & Education 31 Synthetic Web Sling Stitching Stitching Stitching is the only method allowed to attach end fittings to webbing, or to form eyes Office of Training & Education 32 Synthetic Web Slings Remove from Service Remove from service if any of these are present: • Acid or caustic burns • Melting or charring of any part • Snags, punctures, tears or cuts • Broken or worn stitches • Distortion of fittings Office of Training & Education Heat Damage 33 Storing Materials Secure materials stored in tiers by stacking, racking, blocking, or interlocking to prevent them from falling Post safe load limits of floors Keep aisles and passageways clear Office of Training & Education 34 Storing Materials Don’t store noncompatible materials together In buildings under construction, don’t place stored materials within 6 feet of a hoistway or floor opening Office of Training & Education 35 Fall Protection Employees who work on stored materials in silos, hoppers, or tanks, must be equipped with lifelines and harnesses Office of Training & Education 36 Brick Storage Stack bricks in a manner that will keep them from falling Do not stack them more than 7 feet high Taper back a loose brick stack after it is 4 feet high Office of Training & Education 37 Lumber Remove nails before stacking Stack on sills Stack lumber so that it is stable and self supporting Office of Training & Education 38 Housekeeping Keep storage areas free from accumulated materials that cause tripping, fires, or explosions, or that may contribute to harboring rats and pests Office of Training &
