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

• Risks
• Poor posture (tilted head, hunched)
• Poor lighting
• Long reach
• Poor chair position
• Poor monitor position
• Resting on sharp edges

18
Office Ergonomics

• 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
