Kickoff Activity – What’s Changed
MATERIAL HANDLING –THEN AND NOW
What basic aspects of material handling have changed relatively little over time?
What aspects have changed a great deal?

Material-Handling BasicsTo prevent injuries when handling materials:
• Pre-plan the task.• Wear appropriate PPE.• Follow proper lifting procedures.• Be aware of hazards posed by heights and suspended
loads.
Introduction to Material Handling 00109-15
BASIC GUIDELINES
• Assess the situation before attempting a lift. • Wear the proper clothing. • Use the appropriate PPE. • Follow established policies.
Introduction to Material Handling 00109-15
GUIDELINES FOR LOWERING A LOAD
Introduction to Material Handling 00109-15
• Size up the load first. • Lower the load in the same way it would be lifted.• Treat the area that the load is being lowered into
as a fall zone.
GUIDELINES FOR LOWERING A LOAD

Safe Lifting Technique
Stacking and Storing Materials
Introduction to Material Handling 00109-15
Stack loose bricks no higher than seven feet (2.1 m). Above four feet (1.2 m), begin stacking
two inches (5 cm) in from the edge, continuing in this manner
for each additional foot of height up to seven feet (2.1 m).
Stacking and Storing Materials
Introduction to Material Handling 00109-15
Follow safety guidelines for stacking and storing items such as:• Cartons• Lumber• Pipes• Items that should be chocked• Items that should be tied down or banded • Bags• Bricks• Masonry blocks• Flammable materials
Stacking and Storing Materials
Introduction to Material Handling 00109-15
Stack loose bricks no higher than seven feet (2.1 m). Above four feet
(1.2 m), begin stacking two inches (5 cm) in from the edge, continuing in
this manner for each additional foot of height up to seven feet (2.1 m).
Working from HeightsSafety Guidelines
• Use a safety harness with a fall-arrest lanyard at heights over 6 feet (2 m).
• Use a rope to raise or lower tools and materials. • Tie off tools and materials to keep them secured in
elevated work areas.• Follow precautions to use ladders safely.• Never stack or store materials on scaffolds or runways.
Introduction to Material Handling 00109-15
Knots Knots and Hitches
• True knots must be unwoven to be unfastened.• Hitches can be undone by pulling in the reverse
direction from that in which the knots are meant to hold.• Key knot-tying terms are: standing end, working end,
standing part, and capsize.

The Square Knot
Introduction to Material Handling 00109-15
THIS…
…not THIS!
The Square Knot
Introduction to Material Handling 00109-15
• The granny knot is the result if the second half knot is tied in the wrong direction when tying a square knot.
• It is a highly insecure knot!
The Square Knot
Introduction to Material Handling 00109-15
The Bowline
Introduction to Material Handling 00109-15
Do not use this knot if the rope may have to be released while under load!
The Half Hitch
Introduction to Material Handling 00109-15
Do not use this knot alone for heavy loads or when
safety is critical!
The Clove Hitch
Introduction to Material Handling 00109-15
Do not use this knot alone; use additional half hitches to make it more secure.

Carts and Dollies
Introduction to Material Handling 00109-15
Cylinder carts are designed for transporting compressed gas cylinders, which are
explosion hazards. Use carts with a partition when transporting oxygen and any fuel gas
cylinder together.
Carts and Dollies
Introduction to Material Handling 00109-15
Dollies are excellent for drums kept upright, making them easy to move on a smooth floor. For transporting a cylinder
longer distances, a drum cart is best.
Pipe Mules and Transports
Introduction to Material Handling 00109-15
PIPE MULES• Two-wheeled devices for transporting medium-length pipes,
tubing, or scaffolding• Also called a tunnel buggy, V-cart, or grasshopper• Requires use of proper lifting techniques and a spotter for
full lengths of pipe
Pipe Mules and Transports
Introduction to Material Handling 00109-15
PIPE TRANSPORT• Similar to pipe mule, but used for larger pieces of pipe• Has frame attached to two rubber wheels• Requires two people to operate it
Operators of equipmentOperators of equipment powered by gasoline or electric motors must…
• be properly trained, certified, and authorized.• know the weight of the load.• never exceed the load-handling capacity of the
equipment.• inspect the equipment before using it.

Concrete
Introduction to Material Handling 00109-15
POWERED WHEELBARROW• Powered by an electric or gas motor • Requires pre-use inspection• Has specific guidelines for safe operation
Concrete
Introduction to Material Handling 00109-15
CONCRETE MULE• A wheeled device for concrete pours in locations where
concrete delivery truck or pump cannot reach• Designed to carry materials such as concrete, sand, or
gravel (concrete-related material)• Requires pre-use inspection
Forklifts
Introduction to Material Handling 00109-15
INDUSTRIAL FORKLIFT• A vehicle with a power-operated pronged platform for lifting,
lowering, and transporting large or heavy loads• Used in smooth terrain areas• Requires daily pre-use inspection
Forklifts
Introduction to Material Handling 00109-15
ROUGH-TERRAIN FORKLIFT• A forklift designed for use on rough surfaces and terrain• Has same safety guidelines that apply to industrial forklifts• Telehandler models have an articulated arm or boom

Wrap UpWhat would be the most appropriate device or practice to use for the following material-handling situation?
Introduction to Material Handling 00109-15
1. A worker on the ground at a job site needs to tie a knot to secure a bucket of tools to a rope so the tools can be hauled up to co-workers who are on an elevated platform.
Use a bowline to secure the rope to the bucket.

2. A worker must stack 50 bags of material onto a pallet in a storage area at a work site.
Stack the bags by stepping back the layers and cross-keying the bags at least every 10 bags
high.

4. A worker must deliver concrete mix to a pour in a location that cannot be reached by a concrete delivery truck or pump. The discharge location is near an open pit.
Use a concrete mule to transport the material. Use a tire stop board or chocks to keep the mule from rolling forward into the pit while the concrete mix is being discharged from the mule.

5. A worker needs to alert a forklift operator that the load is too far forward on the forks.
Use the appropriate hand signal to tell the forklift operator to tilt the mast backward.
