Common WMSD* Hazards in Your Workplace and Some Solution Ideas

*Work-related Musculoskeletal Disorders


This slide show outlines…

…some common WMSD hazards in workplaces, and some ideas for reducing or eliminating them.

  • Links to the following PowerPoint slide shows can be found at the appendix at the end of this slide show.

  • A Five Step Process for Finding WMSD Hazards

  • Recommended Exposure Limits for Preventing WMSDs


Identify WMSD hazards in your workplace

Locate resources and contacts for more assistance

By the end of this slide show, you will be able to…


WMSD Hazards

Some jobs tasks can cause injuries from:

  • Lifting

  • Awkward postures

  • Forceful gripping or pinching

  • Repetitive motions & Intensive keying

  • Hand-arm vibration


WMSDs

  • WMSDs are occupational disorders of:

    • muscles

    • tendons

    • ligaments

    • joints

    • blood vessels

    • nerves


Forceful pinching, gripping

Lifting

Awkward postures

Hand-arm vibration

Hazards to watch for

Repetitive motion & Intensive keying


Lifting


Reduce the weight

Increase the weight

(so people truly can’t lift the item)

Use mechanical assistance

Slide instead of lift

Team lift

Avoid unnecessary lifting

Use mobile storage

Rotate between tasks

Job enlargement

Bring loads as close to the body as possible before lifting them

Remove obstacles

Place objects at a good working height

To lower the risks of lifting…


Awkward Postures


Raise, lower or tilt the work for easier access

Use a stool for lower level work

Alternate between bending, kneeling, sitting, and squatting

Use an elevated work platform or rolling stairs for higher level work

Use tools with longer handles

Limit overhead storage to infrequently used items

To lower the risk of awkward postures…


Forceful Pinching and Gripping


To lower the risk of forceful gripping…

  • Use lighter tools

  • Suspend the tool

    with tool counter-balancers

  • Use longer lever arms on tools

  • Use hand trucks, carts or conveyors instead of carrying loads


a Pinch Grasp:

a Power Grip:

To lower the risk of pinching…

Change from pinch to grip:

The upper box has cut out handles which allow a much more comfortable and less stressful grip on the box.

is up to 5 times stronger than


Reducing pinching…

Change pinching to gripping


Repetitive Motion and Intensive Keying


To lower the risk of Repetitive Motion and Intensive Keying…

  • Eliminate unnecessary motions

  • Use power tool instead of hand tools

    (He’s using a power drill rather than a ratchet.)

  • Automate the task

  • Enlarge the job

    (Substitute some tasks that don’t include repetitive motions or keying.)


Hand-Arm Vibration

A link to a Hand-Arm Vibration database is in the appendix at the end of this presentation. When searching for a low vibration tool, look for the lowest vibration level (VL).


To lower the risk of Hand-Arm Vibration…

  • Use anti-vibration gloves

  • Isolate the vibration from the user

  • Use low vibration tools


The WISHA Ergonomics Ideas Bank

This is a searchable database with over 700 ideas for solutions to ergonomic challenges
