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
