Ergonomics—
The Case of the Ruptured Tendon

Ergonomics and MSDs
1.8 million work-related MSDs each year
Ergonomics—science of fitting job to the worker
MSD—injury of the nerve system or tissue
Carpal tunnel syndrome, tendinitis, etc.
Shooting pain, stiffness, swelling, numbness

Take a Look at the Facts
Employee is working
at a manufacturing facility
moving wood from
shelving to pallet lift
Shelving is waist high
Pallet lift is slightly
higher than shelving

Take a Look at the Facts (cont.)
Employee lifts wood stock off shelving
Wood stock is placed onto pallet lift
Employee ruptures tendon near bicep
Employee says he did nothing out of the ordinary
What Do You Think Went Wrong?
Do you think job repetition had something
to do with this injury?
Do you think the weight of the wood stock
contributed to the injury?
Do you think the worker was able to use
correct lifting techniques?
How does the proper use of a lift reduce
the potential for injury?

Let’s Review the Causes
Worker was:
Lifting with an
awkward posture
Lifting two pieces at a time
Not using the
pallet lift effectively
Exposed to repetitive motion

Ergonomic Risk Factors
Repetition
Force
Awkward postures
Contact stress
Vibration

Keys to Ergonomic Lifting
Use correct lifting techniques
Items between knee
and shoulder height
Decrease weight of
objects or distance carried
Use material-handling aids
Do not exceed your
lifting limits

Don’t Let It Happen to You
Change positions,
take stretch breaks
Maintain good posture
Identify and eliminate
ergonomic risk factors
Use material-handling aids
Report MSD symptoms
