2. INTRODUCTION
An Introduction to Ergonomics. What
is Ergonomics? “The scientific discipline
concerned with understanding of
interactions among humans and other
elements of a system, and the profession
that applies theory, principles, methods
and data to design in order to optimize
human well-being and overall system
performance”.
Definition for it,
Ergonomics can roughly be defined as
the study of people in their working
environment. More specifically, an
ergonomist (pronounced like economist)
designs or modifies the work to fit the
worker, not the other way around. The
goal is to eliminate discomfort and risk
of injury due to work.
3. NEED OF ERGONOMICS
When safety is a value, rather than a priority, it's
almost unspoken. It is an expectation from
management, employees, vendors and the public at
large. Safety is built into and becomes part of the
corporate fabric, part of the company's DNA.
Ergonomics also must be incorporated and seen as a
value. It needs to be built into a corporate culture and
be integrated into everything any company does on a
daily basis.
Implementing ergonomic solutions can make
employees more comfortable and increase
productivity. Why
is ergonomics important? Ergonomics is important
because when you're doing a job and your body is
stressed by an awkward posture, extreme temperature,
or repeated movement your musculoskeletal system is
affected.
4. MAN MACHINE
RELATIONSHIP
Human–machine system is
a system in which the functions of a
human operator (or a group of
operators) and a machine are
integrated.
Human machine system
engineering is different from the
more general and well known fields
like human–computer
interaction and sociotechnical
engineering in that it focuses on
complex, dynamic control systems
that often are partially automated
(such as flying an airplane). It also
studies human problem-solving in
naturalistic settings or in high-
fidelity simulation environments.
5. OBJECTIVE OF
ERGONOMICS
4. To improve the design of machine at the initial design
stage or later whenever the existing product or process is
modified.
Thus ergonomics helps in:
(a) Developing most comfortable conditions related
to climate, lighting, ventilation and noise level;
(b) Reducing the physical work load;
1. To optimize the integration of man and
machine in order to increase productivity
with accuracy.
It involves in the design of:
(a) A work place suitable for the worker,
(b) Machinery and controls, so as to
minimize mental and physical strain on the
worker to enable the improvement in
efficiency,
(c) A favorable environment for
performing the task most effectively,
(d) Task and work organization,
2. To take care of the factors governing the
physical and mental strain (i.e. fatigue) so
as to get maximum satisfaction for the
worker which at the same time enhances
the productivity.
3. Attempts to minimize the risk of injury,
illness, accidents and errors without
compromising productivity.
6. APPROACH TO
ERGONOMICS
Ergonomics takes a holistic
approach. It looks at all aspects of
the work, from the capabilities of
the person through to the structure
of the overall work system and their
interactions.
A concentric model can be used to
illustrate this approach.
7. BENEFITS OF ERGONOMICS
•Improves Health. People who work
in ergonomic workplaces have
improved health. ...
•Improved Mental Insight. ...
•Higher Productivity Levels. ...
•Decreased Pains. ...
•Higher Quality Work. ...
•Eliminates Hazards. ...
•Increased Employee Engagement. ...
•Encourages Safety.
8. APPLICATION OF
ERGONOMICS
There are plenty of reasons that justify the
application of ergonomics. It reduces the risks of
problems that can get the employees sick and
injured, the cost of which in turn is borne by the
companies.
Ergonomics is profitably applied in following three
areas:
1. Design of Man-Machine Systems.
2. Design of Consumer Goods and Service
Systems.
3. Design of Working Environment.
9. CONCLUSION
Ergonomics helps people to be
more comfortable at work, reducing
stress and injury caused by
incorrect positioning and repetitive
tasks. As a good user, we need to
use ergonomics because it give big
influence in our life.
