A similar classification of the movements of the corresponding members of the leg is available. 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. The immediate Essays on ergonomics area is the surface immediately in front of the operator where the two arcs of the normal working area overlap.
Due care must, therefore, be taken to position all the materials well within his cone of vision. 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 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. 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 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 other words, ergonomics Essays on ergonomics help in increasing the productivity of the managerial brain power.
The contextual analysis of the ILO definition, therefore, provides a more meaningful basis for understanding ergonomics. 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 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.
During inspection, as much of the work as possible must take place in front of the operator. Ergonomics is derived from two Greek words: 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.
Ergonomics can be applied in all schemes of human activity, be it in offices, factories, shops, ships, air, and even in space. The working area of an operator may be categorized into three groups: This subject was developed during World War II as a result of the coordinated efforts of physiologists, psychologists and the design engineers.
In this process, he tries to ensure job satisfaction for the workers, which, inter alia, increases their productivity. The immediate working area is most suitable for bi-manual operation. Two arcs made by the fingers using the elbow as the pivot bind this area. It is not desirable to place anything outside the maximum working area.
Covering the whole perimeter of the normal working area would impose undue eyestrain and sometimes involves excessive head movements. The space between the normal and the maximum working areas is accessible through a class four movement.
The normal working area is one that can be reached by the operator using any movement up to and inclusive of class three movements. The field of vision should also be taken into account while considering the working areas.
Workplace layout, postures, motion and movements, fatigue, monotony and relaxation allowances, comfort, safety and health working hours and shift work conditions. Some of the areas where ergonomics has been successfully applied are as under: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.
Office ergonomics serve important functions in preparing for, and responding to, workplace critical incidents. Workplace critical incidents are. Risk Management: Ergonomics in the Workplace The purpose of this paper is to discuss ergonomics in the workplace through a risk management perspective.
/5(5). 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.
