Ergonomics defined

As discussed in ANSI Z-365 (1999), surveillance is defined as the ongoing systematic collection, analysis, and interpretation of health ruid exposure data in the process of describing and monitoring work-related cumulative trauma disorders. Surveillance is used to determine when and where job analysis is needed and where ergonomic interventions may be warranted. 

Allow job task characteristics to define ergonomic interventions... 

Psychophysiological stress-and-stiain research in ergonomics is an approach lhat has problems in an absolute evaluation of working conditions Zero points, maxima and minima, linearity, and so forth, of scales for stressors, activities, or strain are neither known nor easily definable in a reproducible marmer. 

The study of ergonomics attempts to improve performance by optimizing the relationship between people and their work environment. Ergonomics has been defined as a discipline that investigates and... 

In small and medium size product, assembly, the work-place for assembly should be arranged in an ergonomically optimal way. This is beneficial for the assembly worker since it will minimize the physical strain during the working day. It will also provide the most efficient execution of the assembly tasks. Based on experience over long time, certain elementary rules for good assembly workplace layouts have been established. These rules are based on definition of movement classes for the assembly subtasks. Five classes are defined ... 

I had previously defined ergonomics as the art and science of designing the work to fit the worker. I now use this definition ... 

In Chapter 19, Applied Ergonomics Significance and Opportunity, I refer to an article by Alphonse Chapanis titled To Communicate the Human Factors Message, You Have to Know What the Message Is and How to Communicate It. One of his themes is that human factors engineering has to be defined and its practitioners must know what it is to be able to communicate about it successfully. Safety professionals have the same need. 

WHY DEFINE ERGONOMICS TO INCLUDE PRODUCTIVITY AND COST EFFICIENCY... 

The enterprise identifies and defines human-factor considerations (e.g., design space limits, climatic limits, eye movement, reach, ergonomics, cognitive limits, and usability) that affect oprantion of the Systran under development. The enterprise identifies which human factors are constraints and which can be changed based on trade-off analyses. 

Once the characteristics of the views have been defined, the third step concerns the drawing of these views, generally by means of graphic editors. Editing views leads to a primary set of views, called synopsis. The ergonomic quality of this set must be assessed in order to improve the legibility of the information. So it is necessary to apply a set of ergonomic criteria with respect to the human information acquisition capacities. These criteria concern especially ... 

The limits of movement defined at a joint or landmark of the body. Stresses on the connective tissues at a joint increase as the joint moves towards the limit of its range of motion. Used in ergonomic evaluations.
