Mechanical material handling accidents l.jpg
Mechanical Material Handling Accidents

  • A Small Portion of the Material Handling Problem

  • Potentially Severe or Fatal Injuries


What are back injuries l.jpg
What Are Back Injuries?

  • Low Back Pain

  • Low Back Impairment

  • Low Back Disability

  • Low Back Compensation


Low back pain frequency l.jpg
Low Back Pain Frequency

  • Affects 80% of People In Their Lifetime

  • Impairs 11%

  • 28% of Workers Disabled

  • Affects 31 Million Americans

  • Four Times Greater Risk After First Episode


Low back pain cost l.jpg
Low Back Pain Cost

  • $16 Billion Per Year

  • Average Cost is $8,400

  • Median Cost is $359

  • 25% of All Cases = 90% of All Costs


Low back pain factors l.jpg
Low Back Pain Factors

  • Excessive Weights and Forces

  • Undesirable Body Motions

    • Bending

    • Reaching Out

    • Twisting

  • Prolonged Sitting

  • Vibration


Excessive weights and forces associated with l.jpg
Excessive Weights and Forces Associated With

  • Lifting and Lowering Tasks

  • Pushing and Pulling Tasks

  • Carrying Tasks


Excessive weights and forces task analysis l.jpg
Excessive Weights and Forces Task Analysis

  • Measure Weights & Forces

  • Determine Frequency & Duration

  • Measure Distances

    • Hand Distances

    • Pushing & Pulling Distances

    • Carrying Distances


Ergonomics and low back pain benefits l.jpg
Ergonomics and Low Back Pain Benefits

  • Return to Work Sooner

  • Reduce Low Back Disability and Compensation

  • Can Prevent Initial and Recurring Episodes


Return to work l.jpg
Return to Work

  • Average is 14 Days (22 States)

  • Probability

    • Off Work Six Months or More 50%

    • Off Work One Year or More 25%

    • Off Work Two Years or More NIL


Controls l.jpg
Controls

  • Traditional Approaches

    • Training

    • Medical

  • Ergonomics Approach

    • Task Redesign


Other ideas l.jpg
Other Ideas

  • Employee Suggestions

  • Try New Equipment & Ideas Before Full Implementation

  • Combine Tasks (e. g., Assembly & Quality Control)

  • Share Ideas Between Plants

  • Keep an Open Mind


Bending l.jpg
Bending

  • Do workers pick up material off the floor?

  • Can we use tables, platforms, etc.?


Twisting l.jpg
Twisting

  • Do workers have room to turn?

  • Can we lay out work area differently?


Pushing pulling l.jpg
Pushing/Pulling

  • Are trucks and carts difficult to push or pull? Why?

  • Are they periodically inspected?


Handling aids l.jpg
Handling Aids

  • Are mechanical handling equipment, devices, or aids available?

  • Do workers use them?

  • Are the devices appropriate for the job?


Task redesign l.jpg
Task Redesign

  • Optimum Work Level

  • Mechanical Devices

  • Workplace Layout

  • Minimize Rehandling


Training for material handling l.jpg
Training for Material Handling

  • Use of Job Aids

  • Use of Mechanical Equipment



Suggested safe lifting rules l.jpg
Suggested Safe Lifting Rules

  • Lift Comfortably

  • Avoid Unnecessary Bending

  • Avoid Unnecessary Twisting

  • Avoid Reaching Out

  • Avoid Excessive Weights

  • Lift Gradually

  • Keep in Good Physical Shape
