  1. Ergonomics Making the job fit the worker

  2. Ergonomics looks at: • Work station • Tools • Motions • Physical condition • Physical limitations • Environment 1

  3. Musculoskeletal disorders • Musculoskeletal disorders = MSDs 2a

  4. MSD symptoms • Dull, aching sensation • Discomfort with movements • Tenderness to the touch • Burning sensation • Pain • Tingling • Cramping • Stiffness 2b

  5. Common MSDs • Tendinitis • Tenosynovitis • Trigger finger • Raynaud’s syndrome • De Quervain’s disease • Carpal tunnel syndrome 2c

  6. Workplace risk factors • Repetitive motions • Fixed / awkward postures • Vibration • Force • Twisting / bending • Elevation of elbows • Lifting 3a

  7. Workplace risk factors • Inappropriate tools • Continuous contact • Restricted clearance • Improper seating/support • Bad body mechanics • Inadjustable equipment 3b

  8. Identify risk factors • Management/employee involvement • Audit work stations • Audit procedures 4a

  9. Engineering controls • Preferred method • Work station design • Tool design • Equipment design 5a

  10. Work station design Provide adequate: • Work space • Work height • Support • Storage space • Machine controls 6a

  11. Work station design • Reduce static loading • Raise / lower working height • Remove hard / sharp edges • Provide mechanical advantages • Insulate heat / cold 7a

  12. Work station redesign • Provide seating / support • Improve material orientation • Improve layout 7b

  13. Tool selection should minimize: • Awkward, bent grip • Vibration • Excessive grip strength • Awkward positions to exert force • Repetitive motions 8a

  14. Administrative controls • Job rotation • Shift length • Overtime management • Rest breaks • Production rates 9a

  15. Work practice controls • Use proper techniques • Avoid unnecessary steps • Job training • Exercise/ conditioning 10a

  16. Medical management • Early reporting & treatment • Symptoms survey • Medical treatment • Recordkeeping 11a

  17. Back disorders • Sprains • Strains • Ruptured/slipped disks • Muscle spasms 12a

  18. Back pain factors • Improper posture • Poor physical condition • Improper lifting 12b

  19. Proper lifting • Size up the load • Bend your knees • Do not twist • Clear path • Lower slowly • Push carts/dollies 12c

  20. Summary • Define ergonomics • MSDs • Risk factors • Controls • Medical management • Proper lifting 13a
