What is Ergonomics?
It is . . . fitting the work to the worker
• Ergon = Greek for “work”• Nomos = Greek for “laws of”• The Study of Work• Applies both on and off the job

Benefits of Ergonomics• Decreased injury risk
• Increased productivity
• Decreased mistakes/rework
• Increased efficiency• Decreased lost work days
• Decreased turnover
• Improved morale

Ergonomic Risk Factors• Repetition• Awkward posture• Forceful exertion• Static posture• Mechanical contact • Stress• Temperature• Vibration

1. Use a good chair with a dynamic chair back and sit back in this
2. Top of monitor casing 2-3" (5-8 cm) above eye level
3. No glare on screen, use an optical glass anti-glare filter where needed
4. Sit at arms length from monitor 5. Feet on floor or stable footrest 6. Use a document holder, preferably
in-line with the computer screen 7. Wrists flat and straight in relation
to forearms to use keyboard/mouse/input device
8. Arms and elbows relaxed close to body
9. Center monitor and keyboard in front of you
10. Use a negative tilt keyboard tray with an upper mouse platform or downward tilt able platform adjacent to keyboard
11. Use a stable work surface and stable (no bounce) keyboard tray
12. Take frequent short breaks (microbreaks)

Tilt the work surface instead of the wrist.
Stand with weight evenly distributed between feet. When standing for long periods of time, rest one foot on a sturdy object above floor height and switch legs periodically

Keep elbows close to the body.
Reduce the need for outstretched arms. Use a higher work surface.

Avoid bending over your work.
Avoid overhead work. Use a ladder.

Bend the tool, not the wrist.
Use tools that distribute pressure evenly across the palm.

Squatting
Better . .
Use tools or extensions that allow you to stand upright

Highly repetitive motion
Better . .
•Use properly designed ergonomic tools
•Vary your motions
•Rotate to other tasks

Using the knee/hand as a hammer
Use a mallet Use a tool
Better . .

Moderate to High Hand -Arm Vibration
Use low vibration tools if available
Maintain tools
Use anti-vibration gloves or tool wraps
Take frequent pauses
Stretch your hands and arms
Better . .

Lifting• Size up the load
• If too heavy for one person, get help!
• Lift together or use mechanical assistance

Unsafe Lifting Techniques

Pushing and pulling
Use your legs and tighten abdominal muscles
Has potential for straining arm, shoulder and neck muscles
