According to the Bureau of Labor Statistics,

more than one million workers suffer back

injuries each year, and back injuries account

for one of every five workplace injuries

One fourth of all compensation claims involve back

injuries, which cost employers billions of dollars

Add to that the employees pain

and suffering

Introduction


3/28

Material Handling and Lifting Injuries areexceedingly painful, difficult to heal, and

have an effect on everything you do

After suffering just one back injury, youare much more likely to experience

another one later on

It is important to learn

how to avoid injuring orre-injuring your back

ObjectivesAt the end of this presentation, you should

be familiar with the following topics:

Forces involved with lifting

Risky moves associated with lifting Contributing factors to materials handling/lifting injuries

Injury prevention

Proper lifting procedures

Using the Calculator For Analyzing Lifting Operations Body Management

Work-specific training requirements


5/28

The Forces InvolvedThe amount of force placed on your back under certain conditions can

be surprising. Anytime you bend or lean over to pick something up

without bending your knees, you put tremendous pressure on your

lower back.

Think of your back as a lever. With thefulcrum in the center of the lever, it only

takes ten pounds of pressure to lift a

ten pound object.

However, if you shift the fulcrum to one side, it takes much more force to

lift the same object.Your waist actually acts like the fulcrum in a

lever system, and it is not centered. In fact, it operates on a 10:1

ratio. Lifting a ten pound object actually puts 100 pounds of

pressure on your lower back.


6/28

The Forces Involved

When you add in the 105 poundsof the average human upper torso,

you see that lifting a ten pound

object actually puts 1,150 pounds

of pressure on the lower back.

Given these figures, it is easy to

see how repetitive lifting and

bending can quickly cause back

problems. Even leaning forwardwhile sitting at a desk or table can

eventually lead to back related

problems.


7/28

Risky MovesCertain actions are more likely to cause back

injuries than others. Anytime you find yourselfdoing one of these things, you should think:DANGER!My back is at risk!

Heavy lifting...especially repetitivelifting over a long period of time

Twisting at the waistwhile lifting orholding a heavy load. (This frequentlyhappens when using a shovel.)

Reaching and lifting...over your head,

across a table, or out the back of a truck.


8/28

More Risky Moves

Lifting or carrying objects withawkward or odd shapes

Working in awkward, uncomfortablepositions...gardening, kneeling, tasks thatrequire you to bend over for long periods of time...

Also, sitting or standing for too longwithout shifting.


9/28

The further you bend, and the more youextend your arms, the more significant

the risk of injury!


10/28

Other Causes of Injuries

It is also possible to injure yourself

slipping on a wet floor or ice

Tripping or falling over obstacles in

the walkway

Improper use of lifting of moving equipment


11/28

Contributing Factors to

Handling/Lifting Injuries

Poor Physical Condition

Your stomach muscles provide a lot of thesupport needed by your back. If you have weak,flabby stomach muscles, your back may not get allthe support it needs, especially when you're lifting

or carrying heavy objects. Good physical conditionin general is important for preventing strains,sprains, and other injuries.


12/28

Poor posture

Is another contributing factor. When yourmother told you to sit and stand up straight,she was giving you good advice. It is best totry to maintain the back in its natural "S"shaped curve. You want to avoid leaningforward (unsupported) when you sit, orhunching over while you're standing.




13/28



Extra weight

Can be a big problem. Rememberthe fulcrum / lever principle? Themore you weigh, the more stress it

puts on your back every time youbend over--on a 10:1 ratio.


14/28


Handling/Lifting InjuriesStress

Tense muscles are

more susceptible to

strains and spasms.


15/28



Overdoing it

Dont be afraid to say,This is tooheavy for me to lift alone.

Its important to recognize your physicallimitations and abilities. Many people haveinjured their backs because they were afraidto ask for help.


16/28

Preventing Back InjuriesThe best way to prevent back injuries is to develop

habits that reduce the strain placed on the back. Thereare some basic things you can do to help.

Avoid Lifting and Bending Whenever You Can!

Place objects up off the floor. If you can setSomething down on a table or other elevated

surface instead of on the floor, do it so you won't

have to reach down to pick it up again.

Raise / lower shelves. The best zone for lifting is

between your shoulders and your waist. Put heavier

objects on shelves at waist level, lighter objects on

lower or higher shelves.


17/28

Preventing Back Injuries

Use carts and dolliesto move objects, instead of carrying them

yourself. (Remember that it is better on your back to push carts

than it is to pull them.)

Use cranes, hoists, lift tables, and other lift-assist devices

whenever you can.


18/28

Use Proper Lifting Procedures

You can't always avoid lifting, but there areways to reduce the amount of pressure placedon the back when you do so

By bending the knees, you keep your spine in abetter alignment, and you essentially take awaythe lever principle forces.

Instead of using your back like a crane, youallow your legs to do the work.


19/28


Take a balanced stance with your feetabout a shoulder-width apart. onefoot can be behind the object and theother next to it.

Squat down to lift the object, butkeep your heels off the floor. Get asclose to the object as you can. Keepyour back straight.

Use your palms (not just your fingers)to get a secure grip on the load.Make sure you'll be able to maintain ahold on the object without switchingyour grip later.


20/28


Lift gradually (without jerking) using your leg, abdominal andbuttock muscles and keeping the load as close to you as possible.Keep your chin tucked in so as to keep a relatively straight back andneck line.

Once you're standing, change directions by

pointing your feet in the direction you wantto go and turning your whole body. Avoidtwistingat your waist while carrying a load.

By following these lifting guidelines and bypracticing good body/back management,you can prevent back injuries on the job andat home.


21/28

Other Lifting Tips Reduce the amount of weight lifted.If you're moving

a bunch of books, better to load several small boxes thanone extremely heavy load

Keep a clear view ahead when carrying/moving a load.Never carry a load in front of your face as it forces you tolean or twist and upsets your balance

Use handles and lifting straps

Push a dolly or cart in a linear motion. Never pull,as it forces you to twist at the waist!

Get helpif the shape is too awkward or the object is tooheavy for you to lift and move by yourself!


22/28

How to determine if the load you

are moving is too much. Use the Calculator For Analyzing Lifting

Operations Form. on next slide

Easy to use formula based on factors suchas the weight to be lifted, at whatposition you begin the lift from, the frequencyof lifting, and if twisting is involved

Simple result lets you know if lifting theload could be hazardousor not


23/28What is too heavy?


24/28

It's important to know your body'slimitations, and it's important to beaware of your body position at all times

Learn to recognize those situationswhere your back is most a risk: bending,lifting, reaching, twisting, etc.

Then take measures to avoid an injury byusing this training whenever you handleor lift materials

Practice Body Management

Very Important..

Your job may require the use of specialized tools

or equipment, not mentioned in this lesson, to

help facilitate the handling and movement ofmaterials

Training is available for material handlingactivities specific to YOUR work area!

Actual hands-on training and practice, where thecontent of this course is applied, should becompleted as soon as possible.
