The immediate working area is most suitable for bi-manual operation. An ergonomist, for effective accomplishment of work this to integrate the work system which broadly includes the tasks, working equipment, working conditions and working space with the capabilities and requirements of work.
The working area of an operator may be categorized into three groups: Many alternative terms such as human engineering, human factors in engineering, engineering psychology, applied experimental psychology, applied and human engineering research, and man-machine system analysis, are used to designate the discipline.
Some of the areas where ergonomics has been successfully applied are as under: Since then, with the advancement of experimental physiology, psychology, and method study, the subject delved deeper into the human make-up for a better and scientific understanding of the efforts of the working conditions and environment on the human body and mind.
The normal cone of vision, without head movement, is restricted. Such input information makes the task of the work study practitioner more scientific and result oriented. In this process, he tries to ensure job satisfaction for the workers, which, inter alia, increases their productivity.
Frank Bunker Gilberth and his wife Lillian elaborated the principles of motion economy and introduced the rest pauses and spacing out of work to reduce the fatigue and eliminate the stress. The field of vision should also be taken into account while considering the working areas.
Two arcs made by the fingers using the elbow as the pivot bind this area. Ergonomics is a discipline at the service of the management from the very planning and design stage of a work system.
For better understanding, classes of movements can be grouped under the following five categories, based on the pivots around which the body members move, as shown in Table Ergonomics can be applied in all schemes of human activity, be it in offices, factories, shops, ships, air, and even in space.
It is die study of the effects of a work system on the workers and it aims at fitting the work to the mean to increase their efficiency, comfort, and satisfaction. The immediate working area is the surface immediately in front of the operator where the two arcs of the normal working area overlap.
A similar classification of the movements of the corresponding members of the leg is available. The space between the normal and the maximum working areas is accessible through a class four movement. Ergonomics is derived from two Greek words: Due care must, therefore, be taken to position all the materials well within his cone of vision.
Health, physique, anthropometric data, personal background, education, training, experience, age, sex, intelligence, aptitude, reaction time, interest, personality characteristics, temperament, attitude towards work, motivation, etc.
Anything beyond the maximum working area may be reached only through a class five movement, including body bending or stretching. Physical loads, perceptual loads, mental loads, displays and warning systems, controls, compatibility of inputs and outputs.
This single improvement, by itself, without any changes in the methods on the shop floor will lead to a spectacular increase in the overall productivity of the organizations. If the various equipment, materials, and tools are replaced within the normal working area, they can be reached without using the upper arm and shoulder muscles.
Work study, which aims at a scientific analysis of a work system to increase the productivity and satisfaction at work, is dependent on ergonomics for the research data on many facets of human reaction to a given work situation.
The contextual analysis of the ILO definition, therefore, provides a more meaningful basis for understanding ergonomics. Covering the whole perimeter of the normal working area would impose undue eyestrain and sometimes involves excessive head movements.
Its earliest application can be traced to Frederick Winslow Taylor Illumination, ventilation, temperature and humidity, colour dynamics, fumes, dust, odour and smoke, landscape, scenery and garden, cleanliness and sanitation.
During inspection, as much of the work as possible must take place in front of the operator. Workplace layout, postures, motion and movements, fatigue, monotony and relaxation allowances, comfort, safety and health working hours and shift work conditions.
For economy of motion, the movement should be of the lowest classification possible, compatible with the normal capacity of the body member affected.
The findings of ergonomic research, particularly in the field of perceptual and mental loading have a special bearing on the work situation confronting the managerial performance in an organization. In the organization and control of human effort directed to specific ends, management needs to have an appreciation of the human factors involved in a work system.
In other words, ergonomics can help in increasing the productivity of the managerial brain power. This subject was developed during World War II as a result of the coordinated efforts of physiologists, psychologists and the design engineers.
The normal working area is one that can be reached by the operator using any movement up to and inclusive of class three movements.Ergonomics, derived from the root word ergon which means work and nomos which means laws, is the study of the related interaction of humans and the objects being used to perform a specific task, process, or function.
Office ergonomics as is the case with other disciplines in ergonomics all emerged in the s during the world war (McCormick and Saunders ).
Difficulties arouse from soldiers inability to handle technical equipment produced for the war due to physical incompatibility or lack of understanding. Free Essay: Office ergonomics as is the case with other disciplines in ergonomics all emerged in the s during the world war (McCormick and Saunders.
Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.
ADVERTISEMENTS: Ergonomics is derived from two Greek words: ergon meaning work and enomos meaning laws. It is die study of the effects of a work system on the workers and it aims at fitting the work to the mean to increase their efficiency, comfort, and satisfaction.
International Labour Organization (ILO) defined ergonomics as ‘the. Risk Management: Ergonomics in the Workplace The purpose of this paper is to discuss ergonomics in the workplace through a risk management perspective.
