  1. Ergonomics

  2. Ergonomics Job Demands Worker Capabilities A Balance for Optimization

  3. Win/Win Higher Production Higher Quality Compliance Lower Compensation Costs Careers/Employment Longevity Safe Working Conditions Quality of life Morale

  4. Acute: Result from a one time event Cumulative: Result from repeated wear and tear; however, a specific event may have been “the last straw” upon a previously weakened system and thus give the appearance that the problem is acute rather than chronic. {Stephen Konz. “Work Design; Industrial Ergonomics”, Third edition. 1990} Acute Vs. Cumulative Disorders

  5. Some Common Upper Extremity CTD’s • Tendonitis • Tenosynovitis • Trigger Finger • Epicondylitis • Thoracic Outlet Syndrome • Carpal Tunnel Syndrome

  6. Two Kinds of Back Injuries MUSCULAR SPINAL

  7. Safe Lifting Techniques • There are several basic rules of lifting and moving that can help prevent back injuries: • Lift with your legs, not your back; this is because your legs muscles are larger and better positioned over the hips and knees to provide this activity. • Do not twist; instead, always position your hips and feet toward the object you are lifting or moving. • Maintain the natural curves of the neck, upper back and lower back while lifting, moving, and even sitting. • Keep objects close to your body; this reduces the leverage on your spine. • Push, rather than pull when possible. Pushing naturally places your legs in a position to do the work whereas pulling naturally places your back in a forward bent position.

  8. BACK INJURIES

  9. BACK INJURIES

  10. Risk Factors • Repetition • Forceful Exertion • Direct Mechanical Pressure • Static Posture • Inadequate Recovery Time • Awkward Posture • Environmental Stressors

  11. Design Strategies -Back Issues • Minimize pushing/pulling • Minimize load weights • Slide objects • Lower loads rather than lift • Use gravity • Avoid double handling • Use suitable containers • Provide comfortable hand holds • Remove constraints/obstacles • Avoid placing loads on the floor

  12. You may now finish this safety training tutorial by completing the OSHA Assessment Quiz.
