What Is Ergonomics?
The goal of the science of ergonomics is to find a best fit between worker and job
conditions. Ergonomics looks at:
| the physical capabilities
of the human body
the limitations of the
human body |
 |
a person’s work tasks
tools used
the job environment |
The goal is to make sure workers are uninjured, safe, and comfortable, as well as
productive.
Work-related musculoskeletal disorders (WMSDs) are:
- the leading cause of disability for people in their working years
- caused by chronic exposure to these physical stresses
- forceful gripping - kneeling
- lifting - squatting
- bending - vibrating equipment
 
Ergonomics
finds the
best fit
between
worker and
job.
The best way to reduce WMSDs is:
| redesign the tools
redesign how the using the principles of ergonomics
work process is done |
»»using the principles of ergonomics |
Relatively simple changes can make a big difference. When jobs and tools are
ergonomically redesigned, you don't have to rely on a carrot or a stick to get people to
work safely. Injuries are prevented as a natural result of improved work posture, reduced
force, or less repetition. Ergonomic changes should be put into operation along with
worker training on how to work safely.

How Do I Know if I Need an Ergonomics Program?
- Do some jobs cause strain, localized fatigue, discomfort, or pain that does not go away
after an overnight rest?
- Do injury records or workers' compensation claims show hand, arm, or shoulder pain,
low back pain, or carpal tunnel syndrome?
- Do workers visiting the clinic make frequent references to physical aches and pains
related to certain types of work assignments?
- Do jobs involve repetitive and forceful exertions, frequent heavy or overhead lifts, awkward
work positions, or use of vibrating equipment?
- Are cases of WMSDs found among competitors or in similar businesses?
- Do trade publications or employers' insurance information indicate risk of WMSDs?
