Ergonomics is the study of the interaction of a person to job tasks. It involves the relationship of the person=s body to the workstation, equipment and tools. Not all people are proportioned the same way and not all workstations are designed to accommodate different body shapes and sizes. Improper matches can result in accidents and occupational injuries. One way is to know the early warning symptoms of cumulative trauma disorders. The symptoms may be an indication of an improper ergonomics design in the workstation or use of work equipment and tools.
