Presentation Transcript

  1. Task People Ergonomics

  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 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
