4. 3 Goals  Musculoskeletal disorders (MSD)  Quiz

5. 4 What Is Ergonomics?  Science of fitting jobs to the people who do them  Goal is to reduce work- related MSD when their jobs require repetitive reaching, bending, lifting, using force, working with vibrating equipment, and doing other repetitive motions

6. 5 What Are MSDs? Injury to:  Muscles  Nerves  Tendons  Ligaments  Joints  Spinal discs

7. 6 Common MSDs  Carpal tunnel syndrome  Tendonitis  Trigger finger  Raynaud’s syndrome  De Quervain’s disease  Rotator cuff tendonitis  Carpet layers’ knee  Herniated spinal disc  Low back pain

8. 7 Signs of MSDs  Less strength for gripping  Less range of motion  Loss of muscle function  Inability to do everyday tasks

9. 8 Common Symptoms of MSDs  Painful joints such as wrists, shoulders, forearms, knees  Pain, tingling, numbness in hands or feet  Shooting pain in arms or legs  Swelling, inflammation, burning sensation  Fingers or toes turning white  Back or neck pain or stiffness

10. 9 Report all Signs or Symptoms of MSDs  Permanent disability may result if not reported early  Report signs or symptoms of MSDs to your supervisor, Safety Program Manager, Human Resources representative or Worker’s Compensation Insurance Claims Clerk.  Report MSD hazards

11. 10 Repetition  Same motion over and over puts stress on muscles and tendons  How often the movement is repeated  Speed of the movement  Number of muscles involved  Required force

12. 11 Forceful Exertions  Amount of physical effort required to perform a task  Effort needed to control equipment or tools  Type of grip  Weight of object  Body posture  Type and duration of the task

13. 12 Awkward Postures  Reaching  Twisting  Bending  Kneeling  Squatting  Working overhead  Holding fixed positions

14. 13 Contact Stress  Pressing your body against a hard or sharp edge  Puts pressure on nerves, tendons, and blood vessels  Allowing your wrists to rest on the keyboard when typing  Holding tools with hard handles

15. 14 Vibration  Sanders  Grinders  Chippers  Routers  Drills  Saws

16. 15 Goals  Musculoskeletal disorders (MSD)  Quiz

17. 16 Response to MSD Report  Employer performs a job hazard analysis of your job for MSD hazards  Employer takes steps to reduce MSD hazards

18. 17 MSD Incident  Requires medical treatment beyond first-aid  MSD signs or symptoms that last seven or more consecutive days  Treat the same as any other workplace injury.

19. 18 MSD Management  Employee provided with access to a health care professional  Evaluation and follow-up of MSD incident  Temporary work restriction may be necessary

20. 19 Job Hazard Analysis  Determine whether MSD hazards exist  Employee should be involved in identification of MSD hazards  Implement control measures to reduce the hazards  Train employees and supervisors in the affected jobs

21. 20 Goals  Musculoskeletal disorders (MSD)  Quiz

22. 21 Summary  Recognize MSD signs and symptoms  Understand MSD hazards  Learn to take steps to control MSD hazards  Report MSDs the same as any other workplace injury
