INDUSTRIAL
ENGINEERING
ERGONOMICS

2. What is Ergonomics?
- a field of study dealing with the
comfort and safety of the human body
by adjusting tools, work stations and
work processes to fit the worker.

3.  Human-Machine Relationship
-how humans can be best integrated with machines to
maximize safety & task performance.

4.  Human-Machine Relationship
 Office Ergonomics
-the branch of ergonomics dealing with the office
environment.
-the aim of ergonomics is to minimize the
mismatch that occurs between the person and the
job or match the capabilities of humans and the
requirements of the job they are expected to
perform.

5.  Human-Machine Relationship
 Office Ergonomics
 Alexander Technique
- It guides you to do all your normal physical
activities like sitting, standing, etc without tensing
your body. It is NOT AN EXERCISE or a
TREATMENT, but IT EDUCATES you to
improve the quality of your life.

6.  Human-Machine Relationship
 Office Ergonomics
 Alexander Technique
 Psychosocial & Organizational Aspect of Work
-What is a psychosocial factor?
Psychosocial factors are those factors that affect a person
psychologically or socially.
What are psychosocial risk factors?
Psychosocial risk factors are things that may affect workers'
psychological response to their work and workplace
conditions (including working relationships with
supervisors and colleagues).

7.  Human-Machine Relationship
 Office Ergonomics
 Alexander Technique
 Psychosocial & Organizational Aspect of Work
 Ergonomic Injuries
-Ergonomic injuries, often called musculoskeletal
disorders, affect the muscles, tendons, nerves, ligaments,
joints and/or blood vessels. Ergonomic injuries are
typically caused by or made worse with repeated
exertions, awkward positions and / or forceful movements.

8. WORKPLACE INJURY PRECAUTIONS
 Safety Training
 Understanding Job Risks
 Following Safety Precautions
 Preventing Common Injuries

9. Ergonomic Factors to Consider





Does it suit your body size?
Does it also suit all other users?
Can you see and hear all you need to easily?
Do you understand all information presented?
Do errors occur frequently, and is it easy to recover
from them?
 Des the equipment or system cause discomfort if you
use it for any length of time?

10.  Is it convenient to use?
 Is it easy to learn to use?
 Is it compatible with other systems in use?
 Could any of these aspects be improved?
 Do other users have similar reactions?

11. Identifying Problems
 Causes of accident & near misses may be attributable to
people being:
 Unable to see important displays;
 Unable to reach controls;
 Unable to work in a comfortable position;
 Overloaded with to much information at one time;
 Inattentive because there is too little to do or too little
variety
 Medical and absences records may also reveal problems
with particular jobs or tasks

12. Solutions
 Risks can be reduced by changes to designs of
workstations, tools and work organization
 Simple solutions are often better
 Involve and consult the workforce
 Monitor remedial actions to ensure
effectiveness

14. Office Ergonomics
the branch of ergonomics dealing
with the office environment.
It aims to minimize the mismatch
that occurs between the person
and the job or match the
capabilities of humans and the
requirements of the job they are
expected to perform.

15. Sources of injury in the office
•Falls
•Repetitive movements.
• The way you sit or stand (posture).
• Bending over, lifting heavy objects,
or using pressure or force.
• Working with vibrating tools.

16. Facts About Ergonomics
• The average person working at a
keyboard can perform 50,000 to 200,000
keystrokes a day
• Overexertion, falls & RMI are the most
common cause of workplace injury
• An average of 125,000 back injuries due
to improper lifting each year.
• Muscles overuse results in tiny tears in the
muscles and scarring; these contribute to
inflammation and muscle stiffness

17. What causes Nerve Compression or
Entrapment?
1) Repeated motions
2) Tight muscles
3) Inflammation of surrounding tissues
4) Misalignment of the nerve

18. What are 4 Common Nerve
injuries?
I.
Thoracic Outlet Syndrome: brachial
plexus compression d/t muscle
tightness side of neck from poor head
position or slumped posture.
S/Sx: numbness/tingling in hand, made
worse w/overhead activities or cradling
phone b/w ear and shoulder

19. Nerve injuries
II.
Radial tunnel syndrome: compressed
radial nerve @ outside of elbow d/t
repetitive wrist & finger extension or
turning of forearm
S/Sx: Sensations from elbow to base of
thumb w/ wrist weakness a common sx

20. Nerve injuries
III. Cubital tunnel syndrome: ulnar nerve
compression inside of the elbow d/t
repetitive bending of elbow or resting
your elbow on a hard surface
S/Sx: numbness or tingling and
inside of arm w/ tingling to ring & little
fingers

21. Nerve injuries
IV. Carpal tunnel syndrome: compression
of median nerve at level of carpal tunnel
Where is carpal tunnel? Formed @ wrist

29. New ISO standard on the basic
principles of ergonomics
ISO 26800:2011, Ergonomics – General
approach, principles and concepts
“A substantial number of ergonomics standards have been
developed to cover specific issues and different application
domains, but ISO 26800:2011, Ergonomics – General
approach, principles and concepts, will serve as an
umbrella reference for all such standards and provide an
integrated framework bringing together the basic principles
and concepts of ergonomics in one document, and thus
providing a high-level view of the way in which ergonomics is
applied“
Georg Krämer, Chair of ISO Technical
Committee

30. ISO 26800:2011, Ergonomics – General
approach, principles and concepts
ISO 26800 describes these fundamental principles in
order to improve safety, performance and usability
(effectiveness, efficiency and satisfaction), while
safeguarding and enhancing human health and wellbeing, and improving accessibility, e.g. for elderly
persons and persons with disabilities.

31. ISO 26800:2011, Ergonomics – General
approach, principles and concepts
The intended users of this standard are designers,
ergonomists and project managers, as well as
managers, workers, consumers and procurers. Its
specific goal is to facilitate task performance,
safeguard and enhance the safety, health and wellbeing of the worker, or the user/operator of
products/equipment, by optimizing tasks, equipment,
services, and the environment.

32. ISO 26800:2011, Ergonomics – General
approach, principles and concepts
This standard deals with
• the ergonomic approach,
• the principles of ergonomics
• the concepts of ergonomics, and
• the ergonomics-oriented design process and
conformity.

33. ISO 26800:2011, Ergonomics – General
approach, principles and concepts
ISO 26800:2011, Ergonomics – General approach,
principles and concepts, was developed by ISO
technical committee ISO/TC 159, Ergonomics,
subcommittee SC 1

performance
 focuses on the fit between human
cognitive abilities and limitations and the
machine, task, environment

44. Cognitive ergonomics aim to enhance
performance of cognitive tasks by:
user-centered design of human-machine
interaction and human-computer
interaction
design of information technology systems
that support cognitive tasks
development of training programs
work redesign to manage cognitive
workload and increase human reliability

45. Participative Ergonomics
Resources and Support:
• time for the program to develop
• time to develop and implement solutions
• financial resources to make meaningful
changes in the workplace
• management support for the individuals on
the ergonomics team.

46. • Behavioral Based Ergonomics
• Ergonomics of Innovation
How to make it successful?
•
think about how to build upon a successful
blend of existing ideas rather than develop the
newest and most radical ones.
• set a public, inspiring, and difficult goal, and then
break it down into manageable chunks.
• improve the chances that innovative ideas will
spread by encouraging our organizations to identify
possible ways to help others understand and apply
new products, systems, and procedures.
