1 Ergonomics Making the job fit the worker

2 Introduction  Ergonomics  MSDs  Risks  Controls  Lifting  Medical management

3 Section II “Ergonomics”

4 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
