Introduction to Material Handling Learning Targets • • • Students will define a load. Students will establish a pre-task plan prior to moving a load. Students will use proper material-handling techniques. Students will choose appropriate material-handling equipment for the task. Recognize hazards and follow safety procedures required for material handling.
Introduction • Most tasks performed in construction involve handling some type of material or load such as lumber, bricks, or pipes. • A load is defined as the quantity of materials able to be transported at one time by a machine, vehicle, or person – For example, an elevator carrying workers and tools to an upper floor
Materials - Handling Basics • To reduce the risk of injury when manually handling materials – plan the task – wear the appropriate PPE – follow proper lifting procedures. • Before attempting to move any material, check to – make sure the load is manageable – make sure it does not have any protruding nails, wires, or sharp edges.
Materials - Handling Basics • It is important to wear the appropriate PPE when moving or handling equipment. • Wear gloves that fit properly. – tight gloves may increase hand fatigue. – loose gloves reduce grip strength.
Materials - Handling Basics • To reduce the risk of back injuries, you must use proper lifting techniques. • You may have trouble transporting a load that is long and cumbersome. • To lift an object, grasp it firmly and bend your knees. Lift with your legs while keeping your back straight and your head up.
Materials - Handling Basics
Materials - Handling Basics • Overhead loads must be lowered properly to avoid injuries. Reaching above shoulder height can cause stress to the shoulders and back. • Exercising regularly, maintaining a healthy weight, and maintaining good posture all steps that you can take to strengthen your body to minimize back injuries.
Materials - Handling Safety • When working on a job site, you must ensure that you, your materials, and your equipment are safe from any unexpected movement. • In order to work efficiently, workers should properly stack and secure materials. • When stacking and storing materials, never stack cartons higher than the height listed on the carton.
Materials - Handling Safety • Stack pipe and fittings according to size so that you do not have to dig to find the right size.
Materials - Handling Safety • Stack bagged materials by stepping back the layers and cross-keying the bags.
Materials - Handling Safety • Stack bricks no higher than 7’ and taper the brick stacks back 2” for every foot above 4 feet.
Materials - Handling Safety • Taper masonry blocks back one-half block per tier above six feet.
Materials - Handling Safety • Moving materials to a higher location requires planning and safety awareness. • When climbing up or down a ladder, check your pockets and tool belt to ensure that no objects will fall from them. • To move tools to a higher level, place them in a bucket and have them hoisted up by rope.
Materials - Handling Safety • Cables must be pulled properly to avoid injury. – Use only low-stretch rope such as multi-ply and double-braided polyester for cable pulling. • Wrap up the pulling rope after use to prevent others from tripping over it.
Activity: Stacking Material Objective: List important facts about properly and safely stacking different material. Individual Task: Prepare a Tree Map to list li important facts about properly and safely stacking different material. Be prepared to present work to the class. (pp. 9. 3 -9. 5)

Materials - Handling Equipment • Materials-handling devices are used on the job to increase productivity and reduce muscle stress on the body. – can be non-motorized or motorized. • For safe operation of a materials-handling device – always inspect the device before using it to ensure it is functional. • When using the device to move something – place the heaviest load on the bottom to lower the center of gravity and to make the load easier to handle. • If your view is blocked when moving an item – request a spotter to walk in front of you to make sure the path is clear.
Materials - Handling Equipment • A material cart, often called a platform truck, is a wheeled, horizontal platform used to transport materials around a job site. – use caution when moving a cart on an inclined or declined surface, and never load a cart past its weight capacity.
Materials - Handling Equipment • Hand trucks are twowheeled carts that are used to transport large, heavy loads such as gas cylinders and drums.
Materials - Handling Equipment • Roller skids move materials by pushing them on a table surface that is placed on top of two, three, or four roller skids. • Table surfaces options: – come equipped with a rotating table surface – have spikes on the table surface for better grip – simply have a plain surface.
Materials - Handling Equipment • A wheelbarrow is a one- or two wheeled vehicle with handles at the rear used to carry small loads.
Materials - Handling Equipment • A pipe mule is a two-wheeled device used to transport medium-length pieces of pipe.
Materials - Handling Equipment • A pipe transport is similar to a pipe mule but is used to move larger pieces of pipe.
Materials - Handling Equipment • A jack is a portable device used to raise heavy objects by means of a force applied with a lever, screw, or hydraulic press. • When using a jack, never leave it under a load without first blocking the load.
Materials - Handling Equipment • A jack is a non-motorized device that uses force applied with a lever, screw or hydraulic press to raise heavy objects. • A pallet jack, often called a pallet truck, is a device that uses hydraulics to lift and move heavy or stacked pallets.
