1. Motive of Research
Small and Middle Sized Company with poor work-ing conditions
project
How to solve this situation ?
We use a HFE
Dangerous,Labored work,Uncomfortable
position
2. What is “HFE”?• HFE is appropriate and necessary skills to
be a good fit for a job is a job design.
Environment Machinery, equipment
Human
Safety, comfort, convenience, effectiveness, efficient
by designing for human
3.Project plan
Risk Average of
same working
corporates.
Analysis / evaluation
Presented a realistic
improvement
Ergonomic workplace improvement.

Top 10 Basic rules “HFE” Score Card
1. Comfortable fit Uncomfortable fit (Wrist / Neck / Waist)
2. Do not pressure over Power Over power
3. Cut Down on many things Over motion
4. Easy to get STH Can not get to STH
5. A vaild height to work Too low STH
6. Get rid of stress Static posture
7. Reduce on Body pressure Body pressure
8. Clear up Surrounding Not enough to clean up
9. Exercise, Stretching Needs Exercise, Strething
10. A pleasant environment to work Poor lighting equipment
Question investigation1. Motive of Research
Target : Each workerWorkingEnviro-ment
Do you think self – satisfaction about working place? How about working place?(Dust, Noise, Scent, Temperature) How about average working time?
ETC :
Work poses
inconve-nient
How about work poses? (Shoulder, Wrist, Waist, Leg) Have you ever thought about work poses are uncomfort-able? If your working long time after that any pains? Which part are painful? How about pain degree? : (Top , Middle , Low)
ETC : Improve-
mentRequire-
ment
Now your part can be improve Safty system? Which part already improvement?
Which part do you want to improve?
