2 Ergonomics Defined: The Science relating persons and their work, including the factors affecting the efficient use of human energy What is the Goal of an Ergonomics Program? To reduce or eliminate discomfort or physical problems that may lead to more serious Repetitive Motion Injury (RMI s) What are the Strategies to achieve the Ergonomics Program Goal? To identify environmental factors that would create Discomfort or physical problems To arrange the work area in order to reduce discomfort or physical problems

3 FACT OR FICTION: My hands are numb and tingle. I must have Carpal Tunnel Syndrome

4 Fiction! 95% of persons who experience hand numbness or tingling are performing repetitive jobs in a way that causes excessive neuro musculature discomfort

5 FACT OR FICTION: If I go to the Doctor when my job is causing discomfort to my hands, arms, elbow or shoulder, I will be cured by the Doctors Evaluation and Treatment.

6 Fiction! Doctors perform an evaluation and properly diagnose tendonitis or some form of reversible repetitive motion condition, but are unable to address the ergonomic cause of the condition.

7 Multiple Choice Choose the Right Answer(s) Prescriptions filled by the Doctor for Repetitive Motion Injuries include: A) Meds or Pharms (Anti-Inflammatories) B) Physical Therapy C) Ergonomic Assessment and Correction

8 Ergonomic Injury Prevention Lost Day Injuries Recordable Injuries First Aid Injuries ERGONOMIC ASSESSMENT At Risk Behaviors, Procedures & Conditions
