Ergonomics

'is the science and practice of designing

jobs and workplaces to match the

capabilities and limitations of the humanbody(

)rgonomics means *fitting the job to theworker+

'isk (actors

Risk of injury depends upon#

$ Duration of exposure

$ %re,uency of exposure

$ Intensity of exposure

$ 3ombinations of risk factors


14/73

"uration

Duration $ "ou usually need hours of exposurebefore risk factors become a concern

)xposure can be all at one time or cumulativeover the day


15/73

(re)uency

%re,uency is often a concern in#

assembly tasks

sorting tasks

loading or off.loading materials

inventorying products

product stocking

software programming telemarketing

customer service


16/73

Intensity

Intensity refers to#

weight in pounds of items lifted or carried

grip or pinch force of lifted or manipulated items

vibration level /meters:second;1

force on keys when typing


17/73

*ombinations of risk factors

)xposure to more than one risk factor at a

time greatly increases the risk of injury(

%or example#

$ !ending and twisting while lifting

$ Repetitive8 forceful use of the hands with the wrists

bent


18/73

'isk factors for W!"s

Heavy, frequent or

awkward lifting


19/73

+ea,y lifting


20/73

(re)uent lifting

Lifting more than twice per minute


21/73

Awkward liftingLifting above the shoulders8 below the knees8

or at arms length


22/73

Alternati,es to lifting

Use carts, hand trucks, hoists, conveyors orother mechanical assistance

Slide ojects instead of lifting them

Store heavy items where you won!t have toend or reach to lift them

Use ladders to get items down from highshelves

Awkward postures happen

when the work is:

Too low

Too high

Too far away

'educe grip force

>rip with the whole hand8 not just the fingertips

Pick up smaller loads

A,oid pinch grips

Pick objects up from the bottom using whole

hand

What you can do:

Recognie and report symptoms

>et involved in ergonomics


68/73

What are some of the symptoms of W!"s&

Discomfort

Pain

@umbness

4ingling

'ecogni7e and report symptoms

Report symptoms if#

$ Pain is persistent8 severe or worsening

$ Pain radiates

$ 0ymptoms include numbness or tingling

$ 0ymptoms keep you from sleeping at night


70/73

Why is it important to report symptoms&

&inor injuries can easily become chronic

injuries and can sometimes lead to disability8even surgery

)arly treatment is more successful
