    Study Notes

    Ergonomics Control Methods

    • Repetitive motions: Intense keying for more than 4 hours per day can be hazardous
    • Repetitive motions solutions:
      • Arrange work to avoid unnecessary motions
      • Use power tools and machinery
      • Spread repetitive work out during the day
      • Take stretch pauses
      • Rotate tasks
      • Change hands/motions frequently

    Localized Pressure on Body Part

    • Localized pressure hazards:

      • Pressing body against hard or sharp edges
      • Standing/kneeling on hard surfaces
      • Using tools with hard handle surfaces or short handles
      • Using hands/knees as a hammer more than 10 times per hour or 2 times per day

    • Localized pressure solutions:

      • Use tools with longer handles
      • Use tools with padded grips
      • Alternate between bending, kneeling, sitting, and squatting
      • Use sit/stand stools or tables
      • Pad table edges or use tables/desktops with rounded edges
      • Use wrist rests, anti-fatigue mats, knee pads, shoe inserts

    Lifting Objects

    • Lifting hazards:
      • Lifting more than 75 lbs. once per day
      • Lifting more than 55 lbs. ten times per day

      • Combined exposure to several risk factors

    Ergonomic Control Methods

    • Methods for protecting against MSDs:
      • Establish an ergonomics program (training and feedback)

      • Ergonomically designed tools
      • Ergonomically designed equipment
      • Load weight reduction

    Examples of Proper Work Practices

      • Proper lifting techniques
      • Team lift heavy/bulky/awkward loads
      • Stretch
      • Work rotation
      • Task variety
      • Increase rest breaks

    Examples of Personal Protective Equipment (PPE)

    • PPE examples:
      • Gripping gloves
      • Knee pads
      • Vibration gloves
      • Thermal gloves
      • Lifting straps
      • Shoulder harness
      • Lifting braces

    Five Key Points to Remember

    • Important takeaways:
      • Ergonomics helps design the job for the worker
      • Work-related musculoskeletal disorders (WMSDs) can occur in jobs with risk factors
      • Risk factors can be reduced
      • Early reporting is important
      • Workers can contribute to ergonomics changes

    Knowledge Check

    • Ergonomics: Designing the job to fit the worker.
    • MSDs: Account for approximately 33% of all injuries and illnesses.
    • Ergonomic risk factor example: Repetition.
