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.


BASIC GUIDELINES

• Assess the situation before attempting a lift. • Wear the proper clothing. • Use the appropriate PPE. • Follow established policies.


GUIDELINES FOR LOWERING A LOAD


• 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


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).



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



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.


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


THIS…

…not THIS!

The Square Knot


• 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


The Bowline


Do not use this knot if the rope may have to be released while under load!

The Half Hitch


Do not use this knot alone for heavy loads or when

safety is critical!

The Clove Hitch


Do not use this knot alone; use additional half hitches to make it more secure.

Carts and Dollies


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


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


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


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


POWERED WHEELBARROW• Powered by an electric or gas motor • Requires pre-use inspection• Has specific guidelines for safe operation

Concrete


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


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


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

Section 2.2.6 – Hand Signals


Wrap UpWhat would be the most appropriate device or practice to use for the following material-handling situation?


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.



3. A worker needs to move a sealed oil drum from the warehouse to the shop.

Use a drum cart to transport the oil drum.



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.
