1. Ergonomics
People
Task

2. Learning Objectives
At the conclusion of this training you will be able to:
Explain ergonomic principles
Identify risks involved with working
Additionally you will :
Understand how the use of good ergonomic principles keep you safe

3. Applications of Ergonomics

4. Why is Ergonomics Challenging?
People are different

5. Anatomy

6. Anatomy
Tendons

7. Muscles and Joints Need rest to recover Need good circulation
Maintain strength

8. Neutral Position

9. Risk Factors Repetitive Motions Forceful Exertions Awkward Posture
Contact Stress
Vibration

10. Repetitive Motions No Rest for muscles and joints
Inflammation of tendons, nerves & joints
Loss of strength (Muscle fatigue)
Decreased circulation
Body position

11. Forceful Exertions Inflammation of tendons, nerves & joints
Poor grip (gloves, handles)
Loss of circulation
Loss of strength (Muscle fatigue)

12. Awkward Posture Poor circulation Arms above heart Extended reach
Holding a fix position (static)
Twisting or bending

13. Contact Stress Loss of circulation
Inflammation to tendons, nerves & joints

14. Vibration
Poor circulation
Inflammation of tendons, nerves & joints

15. Manufacturing Ergonomics
Risks:
Twisting or extending reach
Overhead Work (Circulation)
Repetition without rest
Standing Static (Circulation)
“Burping cases” (Palm as Hammer)
Resting on sharp edges (Circulation)
Number of task movements

16. Manufacturing Ergonomics
Injury Prevention:
Warm up muscles, joints
Neutral Position
Rotate muscle groups
Do not rest on sharp edges
Good grip
Switch feet positions
Take micro breaks

17. Office Ergonomics Poor posture (tilted head, hunched) Poor lighting
Risks:
Poor posture (tilted head, hunched)
Poor lighting
Long reach
Poor chair position
Poor monitor position
Resting on sharp edges

18. Office Ergonomics Neutral Position Arms close to body
Injury Prevention:
Neutral Position
Arms close to body
Knees bent at 90o, feet flat while sitting
Monitor at correct height
Rest wrists while typing
Take breaks and stretch

19. Ergonomics Team Evaluate each task Reduce the number of movements
Provide Feedback
Provide Ideas
Feasibility

20. If Signs of Injury Exist
Inform Supervisor immediately
Complete an injury report
Rest specific body part
Ice
Early intervention is the key
