ERGONOMICS
• Means laws of work
• Fitting the job to the worker
• Greek word: ergo (work), nomos (laws)
• Study of designing equipment and devices that fit the human body, its movements, and its cognitive abilities.

Aim of Ergonomics
• The main aim of ergonomics is to achieve the
maximum through a healthy person in the
beast working environment through
machines, tools, equipment, manufacturing,
processes without hazardous effects on the
workers.

• Physical Ergonomics: deals with the human
body’s responses to physical and physiological
stress. OR
• Physical ergonomics is concerned with human
anatomical, anthropometric, physiological and
biomechanical characteristics as they relate to
physical activity. (Relevant topics include
working postures, materials handling, repetitive
movements, work related musculoskeletal
disorders, workplace layout, safety and health.)

• Cognitive Ergonomics (engineering psychology):
concerns mental processes as they affect
interactions among humans and other elements
of a system; includes workload, training,
interaction, decision-making, errors, etc. OR
relationship of people to machines OR
• Cognitive ergonomics is concerned with mental
processes, such as perception, memory,
reasoning, and motor response, as they affect
interactions among humans and other elements
of a system. (Relevant topics include mental
workload, decision-making, skilled performance,
human-computer interaction, human reliability,
work stress and training as these may relate to
human-system design.)3/5/2017 10DR ATHAR KHAN - LIAQUAT COLLEGE OF

• Organizational Ergonomics (macroergonomics):
• Organizational ergonomics is concerned with the
optimization of sociotechnical systems, including
their organizational structures, policies, and
processes. (Relevant topics include communication,
crew resource management, work design, design of
working times, teamwork, participatory design,
community ergonomics, cooperative work, new work
paradigms, virtual organizations, telework, and
quality management.)

• Environmental Ergonomics: human interaction with environment
• Ergonomics at work place has to do largelywith the safety of employees e.g. chairs, desksand keyboards etc.
• Pre-placement Examination is a part of -Ergonomics
