  1. BLR’sSafety Training Presentations ErgonomicsGeneral Duty Clause §5(a)(1) of the OSH Act

  2. Goals • Ergonomics and MSDs • Effective Ergonomics Programs • Quiz

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

  4. What Are MSDs? MSDs are injuries and illnesses to: • Muscles • Nerves • Tendons • Ligaments • Joints • Spinal discs

  5. Common MSDs • Carpal tunnel syndrome • Tendinitis • Trigger finger • Raynaud’s phenomenon • De Quervain’s disease • Rotator cuff tendinitis • Carpet layers’ knee • Herniated spinal disc • Low back pain

  6. Signs of MSDs • Less strength for gripping • Less range of motion • Loss of muscle function • Inability to do everyday tasks

  7. 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

  8. Report Signs or Symptoms of MSDs • Permanent disability may result if not reported early • Report signs or symptoms of MSDs to your supervisor or human resources representative • Report MSD hazards

  9. 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

  10. 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

  11. Awkward Postures • Reaching • Twisting • Bending • Kneeling • Squatting • Working overhead • Holding fixed positions

  12. 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

  13. Vibration • Sanders • Grinders • Chippers • Routers • Drills • Saws

  14. Goals • Ergonomics and MSDs • Effective Ergonomics Programs • Quiz

  15. Management Leadership and Employee Participation • MSD reporting and response system • Designate persons with authority and resources to run the program • Policies do not discourage employee participation or reporting of MSDs • Employees participate in development, implementation, and evaluation of ergonomics program

  16. Job Hazard Analysis • Determine whether MSD hazards exist • Implement control measures to reduce the hazards • Employee involvement in identification and control is required • Training for employees and supervisors in affected jobs

  17. Control Methods • Engineering Controls • Work Practice Controls • Administrative Controls • Use of PPE

  18. Evaluate Ergonomics Program • Employer should make sure the program is effective • Ask employees for their opinions • Ensure hazards are being addressed • Make necessary changes

  19. Goals • Ergonomics and MSDs • Effective Ergonomics Programs • Quiz

  20. Summary • Recognize MSD signs and symptoms • Understand MSD hazards • Learn to take steps to control MSD hazards • Report MSDs • Participate in the Ergonomics Program

  21. Quiz 1. Name one risk factor that determines if repetition contributed to an MSD: _________________________. 2. Loss of the muscle function is a sign of an MSD. True or False 3. MSDs are injuries to nerves and ___________________. 4. Name a vibrating tool that could contribute to an MSD: _____________________________________________. 5. The preferred control measure in controlling MSDs is the use of PPE. True or False

  22. Quiz (cont.) 6. Describe a common MSD symptom: ________________. 7. Describe an awkward posture that you may experience while performing your job: _______________________. 8. What does contact stress put pressure on that may result in an MSD? _____________________________________ 9. Employee participation is not needed for an effective ergonomics program. True or False 10. The type of grip is a risk factor to consider when evaluating jobs with forceful exertions. True or False

  23. Quiz Answers 1. How often motion repeated, speed of movement, number of muscles involved, or required forces 2. True 3. Soft tissue 4. Sander, grinder, chipper, router, drill, saw 5. False. Engineering controls is the preferred control measure

  24. Quiz Answers (cont.) 6. Painful joints, tingling or numbness, shooting pain, swelling, pale fingers, back or neck stiffness 7. Reaching, twisting, bending, kneeling, squatting, working overhead, holding fixed position 8. Nerves, tendons, or blood vessels 9. False; employee participation is essential and fundamental 10. True
