14. WMSDs and solutions
WMSDS Possible Causes Solution
Myofascial pain in the neck
and upper back
Working overhead arms in
extended position
Provide Mechanical Lifting Devices
Pain in lower back Sustain Bending  Reduce bending by working in the
level between knee and shoulder
 Use robotic machines to finish
missions required awkward position
Shoulder bursitis Repeated shoulder
movements
Use robotic machines
Carpal tunnel syndrome Repetitive flexion of wrist • Keep wrists and arms in a relaxed,
neutral position.
• Rest the wrist on a soft pad.
Wrist tendonitis Repetitive movements of
wrists
• Keep your wrists straight.
 Don't strain your fingers.
Discs Lifting heavy objectives Use fork-lift to transport heavy items

15. Conclusion:
1. There is an Excessive noise that is
annoying and distracting.
2. The temperature at the workstation is
too hot.
3. Air circulation is too low and there is no
good ventilation system.
