Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 3 MATERIAL HANDLING BASICS Definition of a Load – The quantity of materials able to be carried, transported, or relocated at one time by a machine, vehicle, piece of equipment, or person. Pre-Task Planning Check to make sure that the load is not too big, too heavy, or too hard to grasp. (bulky) Make sure that the load does not have protruding nails, wires, or sharp edges. Make sure the material is something you are able to lift by yourself. If not, ask a co-worker for assistance. Inspect your path of travel. Look out for hazards that could make you trip or fall. If there are hazards in your path of travel, move them or go around them. Always read the warning labels or instructions on materials before they are moved and be aware of potential dangers if you mishandle a particular product.

Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 4 Personal Protective Equipment: It is important to wear the proper PPE when moving or handling materials. Remember the following when dressing to perform materials handling operations: Do not wear loose clothing that can get caught in moving parts. Be sure to button shirt sleeves and tuck in short tails. Remove all rings and jewelry. Tie back and secure long hair underneath your hardhat. If you wear a wristwatch, make sure you wear one that will easily break away if it gets caught in machinery. Wear gloves whenever cuts, splinters, blisters, or other hand injuries are possible. Select gloves that fit properly. Tight gloves may increase hand fatigue. Loose gloves reduce grip strength and may get caught on moving objects or machinery. Gloves should be removed when working with rotating machinery and equipment with exposed moving parts.

Bend your knees and get a good grip. Be sure to lift with your legs, keep your back straight, and keep your head up!

9. Copyright © by NCCER, Published by Pearson Education, Inc. Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 8 Ask a co-worker for assistance when: The load is too heavy (weighing more than 50 pounds) to carry alone. Handling objects longer than 10 feet such as lumber, conduit, pipes, and scaffolding poles. Handling objects that can be affected by wind gusts such as plywood and tarps. Be aware of people or objects that can be struck when turning Never pass any material to another worker unless the person is looking directly at you and expecting to receive it. Lowering Loads from Overhead: Lowering loads from overhead can be very dangerous. By the time you know it is too heavy, it is already too late! Before you attempt to lower an overhead load, consider the following: Size up the load, if it looks like it took more than one person to put it up there, it is probably too heavy for one person to get it down. Ask yourself “how did it get up there?” The way it was put up there is probably the best way to get it down. Lower objects down the same way you would lift them up. Keep your knees bent and your back straight.

Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 9 Stacking and Storing Material Observe the following guidelines when stacking and storing materials: Keep aisles and passageways clear in the storage area. Materials stored in cartons should be kept away from rain and moisture. Stack lumber on level, solidly supported racks, and remember to remove all nails in recycled lumber. Chock all material such as pipes, drums, tanks, reels, trailers, wagons, as necessary to prevent rolling or moving. Tie down or band all light, large surface materials that might be moved by the wind. Store flammables, such as gasoline, in a well ventilated area away form danger of ignition or in an approved flammable storage cabinet.

18. Copyright © by NCCER, Published by Pearson Education, Inc. Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 17 Working From Heights: Moving material to a higher location requires planning and safety awareness. Use a safety harness when working at heights over six feet. Never throw tools, equipment, or materials to a worker on a higher level or down to a worker on a lower level. Instead, use a rope.

19. Copyright © by NCCER, Published by Pearson Education, Inc. Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 18 WORKING FROM HEIGHTS - CON’T. When climbing down a ladder, check your pockets and tool belt to ensure that no objects will fall of them or get caught on them on the way. Always keep your hands free when climbing a ladder. Place tools or materials in a bucket and hoist them to your work platform. WORKING WITH CABLES On construction sites, you may be required to pull various types of cables through conduit and wire ways, or run it through or over walls, over ceilings and under floors to install it at a desired location.

20. Copyright © by NCCER, Published by Pearson Education, Inc. Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 19 The following are important safety precautions that will help reduce the chance of being injured while pulling cable: Read and understand both the operating and the safety instructions of the pull system before pulling cable. When moving reels of cable, avoid back strain by using proper lifting techniques as discussed earlier. Also, when manually pulling wire, spread your legs to maintain balance and do not stretch. Select a rope that has a pulling load rating greater than the estimated forces required for the pull. Use only low-stretch rope such as multi-ply and double-braided polyester for cable pulling. High stretch ropes store energy much like a rubber band. If the rope, pulling grip, cables, or other component in the pulling system fails, this potential energy will suddenly be unleashed. The whipping action of a rope can cause considerable damage, serious injury, or death. Inspect the rope thoroughly before use. Make sure there are no cuts or frays in the rope. Remember, the rope is only as strong as its weakest point. Wrap up the rope after use to prevent others from tripping over it.

Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 20 Non-Motorized Materials-Handling Equipment Keep the following in mind when using these devices: Use a device that is in good condition and appropriate to the job. Inspect the device before using it to ensure that all parts are intact and functioning properly Plan your route! Be sure all items to be transported are sturdy enough to be moved. Secure any awkward, bulky or delicate objects. Always put the heaviest objects on the bottom of the device to lower the center of gravity and to make it easier to handle. Stagger boxes when you must stack them side by side so that they are locked in. Maintain a safe speed and keep the device under control Keep your hands and feet from underneath the work saving device at all times Try not to stack items higher than your line of sight. If your view is obstructed, use a spotter.

22. Copyright © by NCCER, Published by Pearson Education, Inc. Core Curriculum Module 00109-09 National Center for Construction Education and Research Slide 21 Figure 7 – Material cart Inspect them first! When using a cart with pneumatic tires, check the air pressure. Check to make sure that the surface has adequate traction to avoid slips. Keep your hands away from the edges of the handles to avoid pinching, crushing or cutting your hands. Make sure your load is centered so that it does not roll or fall off. If materials are protruding out in front, use a spotter to walk ahead. Use caution when moving a cart on an inclined or declined surface, and never load a cart past its labeled weight capacity. If the load is too heavy on a decline, it may drag you down. If it is too heavy on an incline, it may back over you.

Motorized materials–handling equipment is powered by gasoline or electric motors. You must be trained, certified, and authorized to operate motorized materials-handling equipment. Know the weight of the object being handled. Know the capacity of the handling device. Ensure your equipment is in good working order and free of damage.
