  1. Ergonomics Making the job fit the worker

  2. Introduction • Ergonomics • MSDs • Risks • Controls • Lifting • Medical management

  3. Section II “Ergonomics”

  4. “Ergonomics” Make the job fit the person

  5. Ergonomics looks at: • Work station • Tools • Motions • Physical condition • Physical limitations • Environment

  6. Section III MSDs

  7. Musculoskeletal disorders = MSDs

  8. MSD symptoms • Dull, aching sensation • Discomfort with movements • Tenderness to the touch • Burning sensation • Pain • Tingling • Cramping • Stiffness

  9. Workplace indicators • Performance deterioration • Quality problems • Absenteeism/turnover • OSHA Logs and WC Reports • Complaints of fatigue and discomfort

  10. Common MSDs • Tendinitis • Tenosynovitis • Trigger finger • Raynaud’s syndrome • De Quervain’s disease • Carpal tunnel syndrome

  11. Section IV Risk factors

  12. Risk factors • Repetitive motions • Fixed / awkward postures • Vibration • Inappropriate tools • Force • Twisting / bending • Elevation of elbows

  13. Risk factors • Continuous contact • Restricted clearance • Improper seating/support • Inadjustable equipment • Lifting

  14. Identify risk factors • Management/employee involvement • Audit work stations • Audit procedures

  15. Section V Controls

  16. Engineering controls • Preferred method • Work station design • Tool design • Equipment design

  17. Work station design Provide adequate: • Work space • Work height • Support • Storage space • Machine controls

  18. Work station design • Reduce static loading • Raise / lower working height • Remove hard / sharp edges • Provide mechanical advantage • Insulate heat / cold

  19. Work station design • Provide seating / support • Improve material orientation • Improve layout

  20. Tool selection should minimize: • Awkward, bent grip • Vibration • Excessive grip strength • Awkward positions to exert force • Repetitive motions

  21. Administrative controls • Job rotation • Shift length • Overtime management • Rest breaks • Production rates

  22. Work practice controls • Use proper techniques • Streamline • Job training • Exercise / conditioning

  23. Section VI Lifting

  24. Back disorders • Sprains • Strains • Ruptured / slipped disks • Muscle spasms

  25. Back pain factors • Improper posture • Poor physical condition • Repeated injury • Improper lifting

  26. Proper lifting • Check load • Bend knees • Do not twist • Clear path • Lower slowly • Push carts/dollies

  27. Section VII Medical management

  28. Medical management • Early reporting & treatment • Symptoms survey • Medical treatment • Recordkeeping

  29. Section VIII Conclusion

  30. Benefits of Ergonomics • Decreased risk of injury • Increased productivity • Increased quality and efficiency • Decrease lost work days/turnover; and • Improve morale

  31. Summary • Ergonomics • MSDs • Risk factors • Controls • Proper lifting • Medical management
