Human Engineering and Ergonomics, is concerned
with the understanding of the basic physical and
psychological attributes of people as these relate to the things that people
use (tools, machines, and environment). The basic objective of ergonomics
is the optimization of person-object relationship. Many jobs
involve continuous or repetitive physical strain with minimum
opportunity for leisure or rest. Examples of repetitive tasks are: chopping
vegetables and other food items in the hotel industry, working with
tools, hand and wrist movements in an oscillatory motion, bending,
lifting, computer and data entry work. These repetitive jobs lead to
injuries/disorders and employees, over a period of time, develop physical
or mechanical stress in particular body parts, which is known as
Cumulative Trauma Disorders (CTD).
In the services sector, especially in the IT and IT-enabled
services, employees seem to be suffering from muscular and skeletal disorders
because of excessive use of mouse and keyboard and long working
hours. Added to this, is the ignorance towards ergonomics by the
employers, which could further lead to health problems like deteriorating
eyesight, stress and burnouts. It is a fact that with the use of
properly-designed ergonomic equipments and
devices, stress-related issues can be reduced to a considerable extent. |
