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
hazards to watch f or

Forceful pinching, gripping

Lifting

Awkward postures

Hand-arm vibration

Hazards to watch for

Repetitive motion & Intensive keying

to lower the risks of 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…
to lower the risk of 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…
to lower the risk of forceful 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
to lower the risk of pinching

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

slide14

Reducing pinching…

Change pinching to gripping

to lower the risk of 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
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
To lower the risk of Hand-Arm Vibration…
  • Use anti-vibration gloves
  • Isolate the vibration from the user
  • Use low vibration tools
