4. Why Ergonomics ?
Enhancing the certain human values including improved
safety, reduced fatigue & reduced stress.
Less cases of unplanned absenteeism.
Better employee morale leading to quality
improvement.
Enhancing the efficiency and effectiveness with which
the work and other activities are carried out.
6. Major organizations involved
The Institute of Ergonomics and Human Factors
International Ergonomics Association (IEA)
National Institute of Industrial Engineering (NITIE)
Operational Health & Safety Advisory services
(OHSAS), British
National Institute for Occupational Safety & Health
(NIOSH), USA
7. Dispensary study
50 to 60 cases of muscular back pain is reported every
month in our Dispensary.
10. Before:
The operator has to
Twist
Stretch &
Bend
Total Cycles/Shift โ 400
Thus the operator has to repeat the
Bend, twist, stretch activity 400 times
a day.
18. Types of Risk
โข Score=1
Low risk
โขScore=2or3
โขchange may be needed
Medium
Risk
โขScore=4 to 7
โขfurther investigation, change soon
High Risk
โขScore=8 to 10
โขinvestigate and implement change
Very High
Risk
โขScore=11+
โขimplement
change
19. Fatigue prone activity using REBA
The assessment in case of REBA is done using the
REBA sheet where we observe the posture and give
the scores.
Based on the final score, the activity can be
categorized.

Reduces workersโ compensation costs
27. โI still need more healthy rest in order to
work at my best. My health is the main
capital I have and I want to administer it
intelligently.โ

Nobel Prize winner for literature
Editor's Notes
Major organizations being involved shows the importance of having an ergonomically efficient environment
The line has been running for 6 years and the change was made one year back so the workers had been doing that for 5 years which leaded to many fatigue cases whereby most of them being cases of muscular back pain. Proper study & improvement could have been done earlier.
