Published on

This one hour webinar will outline common ergonomic risk factor, teach you how to identify them in the workplace, how to quantify and prioritize the risk factors for intervention.

This webinar took place on Thursday, February 17, 2011 from 3:30pm-4:30 p.m. EST (GMT -5)

Identifying and Quantifying Ergonimic Risk Factors

  1. 1. Identifying and Quantifying Ergonomic Risk Factors February 17, 2011 – 3:30-4:30 p.m. EST Presenter: Louise Lynch, PT, CWCE, CEES Co-Owner of Matheson WorkSafe and Matheson Instructor Free 30-Day No-Obligation Trials Available
  2. 2. Brief Overview of Matheson WorkSafe <ul><li>Developed by Industrial PT and Matheson to provide a way for industry and consultants to work together to solve work-related soft-tissue complaints </li></ul><ul><li>Online Tools For “ Solution-Based ” Ergonomics and Case Tracking </li></ul><ul><li>Specific Roles: </li></ul><ul><ul><li>Employee </li></ul></ul><ul><ul><li>Supervisor/HR </li></ul></ul><ul><ul><li>Safety Team Member </li></ul></ul><ul><ul><li>Consultant </li></ul></ul><ul><ul><li>Management </li></ul></ul>
  3. 3. What Is An Ergonomic Risk Factor? <ul><li>“ A variable related to a work that makes a worker more likely to experience a soft tissue injury” </li></ul><ul><li>Correlation, but not necessarily “causal” </li></ul><ul><li>Increased likelihood </li></ul>
  4. 4. What Ergonomic Risk Factors Do We Need to Identify?
  5. 5. <ul><li>Force: internal vs. external </li></ul><ul><li>Posture: dynamic vs. static </li></ul><ul><li>Motions: awkward vs. repetitive </li></ul><ul><li>Vibration </li></ul><ul><li>Temperature </li></ul>Physical Stresses
  6. 6. <ul><li>Force + Repetition + Posture + No Rest = CTDs </li></ul><ul><li>A combination of risk factors rather than any single risk factor may be responsible for the occurrence of MSDs. </li></ul><ul><li>Therefore, identifying all the risk factors that may be present in the job is important. </li></ul>
  7. 7. Quantification of Risk Factors <ul><ul><li>Magnitude </li></ul></ul><ul><ul><li>Repetition </li></ul></ul><ul><ul><li>or Frequency </li></ul></ul><ul><ul><li>Duration </li></ul></ul><ul><ul><li>Recovery </li></ul></ul>
  8. 8. PHYSICAL RISK FACTORS Friction Characteristics: Increased force Presence of Vibration: Increased grip force Type of Grip Used: Pinch or Power Pinch requires 3 times more force Forceful Exertions Weight and Distribution: Load lifted or handled Work Postures: Biomechanics Speed of Movement: Force capacity is reduced
  9. 9. Examples: Forceful Exertions
  10. 10. Grip versus Pinch Grip A power grip is 5 times stronger than a pinch grip
  11. 11. Posture <ul><li>More muscular force is required when awkward postures are used </li></ul><ul><li>Fixed awkward postures: </li></ul><ul><li>Static Loading </li></ul><ul><li>Forces on the spine increase as the distance between the load and the spine increases </li></ul><ul><li>Forces on the spine increase when lifting, lowering, or handling objects with the back bent or twisted </li></ul>
  12. 12. Choosing A Quantification Tool <ul><li>There are many options available </li></ul><ul><li>Look for ones that identify plus quantify </li></ul><ul><li>Example: </li></ul><ul><li>Lift Calculator </li></ul>
  13. 13. Prioritizing <ul><li>Recordables </li></ul><ul><li>Which risk factor? i.e. reduce force and posture first </li></ul><ul><li>Greatest risk factors (depends on tool use) </li></ul><ul><li>Most people risk impacts </li></ul>
