1. Ergonomics Ergonomics recognized as major factor in work place health
One-third of injuries/illnesses stem from over exertion and/or repetitive motion
Cost-$20 billion

2. Ergonomics Improving the fit between the body and an activity
Adapting the environment & using techniques to prevent injuries
ID/reduce risk of MSD’s

3. Musculoskeletal Disorders (MSD’s)
Associated with repetitive strain or damage to muscles, tendons, nerves, and joints
Signals:
Discomfort, swelling, aching, tingling, numbness
Signals come & go, may become constant.
Most frequently affect back & wrists
Left untreated, may limit joint’s motion

4. Personal Risk Factors Associated with ADL Overweight Under fit
Previous injuries
More than one risk factor
More often exposed>risk of an MSD

5. Work Related Risk Factors
Posture
Slouch, twist, reach too far
Repetition
Using same muscles repeatedly
Environment
Vibration, temperature, lighting
Force
Forceful exertion, grip, pull, push, lift
Duration
The longer the duration, the higher the risk
Recovery
Moving body in same way for a long time

6. Controlling the Risk Id & assess risk Reduce risk
How much contact
Reduce risk
Plan on working toward reducing risk factors
Monitor & communicate

7. Reducing the Risk Take responsibility for reducing risk
Apply ergonomic principles both at work and at home
Correct posture problems
Stay near neutral position
Simple adjustments to work area
