•   Ergonomics is the science of fitting jobs to people.

•   The discipline encompasses a body of knowledge about physical abilities and
    limitations as well as other human characteristics that are relevant to job design.

•   Essentially, ergonomics is the relationship between the worker and the job and
    focuses on the design of work areas to enhance job performance.

•   Ergonomics can help prevent injuries and limit secondary injuries as well as
    accommodate individuals with various disabilities, including those with

    musculoskeletal disorders (MSDs).

•   Ergonomics@Work

•   Ergonomics@Work is the campus ergonomic program for faculty and staff. The website provides information
    about the program, classes and workshops; and links to educational materials.


•   Ergonomics is the science of fitting jobs to people. It focuses on designing workstations, tools, and job tasks for
    safety and efficiency. Effective ergonomic design coupled with good posture can reduce employee injuries and
    increase job satisfaction and productivity.

•   Requirements:

     –    Ergonomics training for employees

     –    Identifying, treating, and tracking work-related repetitive motion injuries

     –    Providing worksite evaluations of jobs that have caused repetitive motion injuries

     –    Modifying worksites that have caused repetitive motion injuries
•   What are common ergonomic risk factors?

     –   Repetition
     –   Awkward Body Postures
     –   Force
     –   Contact Stress
     –   Vibration
     –   Heat

•   Common Symptoms

     –   pain
     –   numbness and tingling
     –   stiffness or cramping
     –   inability to hold objects or loss of grip strength

•   Ergonomics is the science of designing the job,
    equipment, and workplace to fit the worker.

•   Proper ergonomic design is necessary to prevent
    repetitive strain injuries, which can develop over time
    and can lead to long-term disability.

•   The four main contributing causes of these injuries
    are quick, repetitive actions, awkward position, use of
    force, and lack of rest.

•   Minimization of repetitive tasks and awkward body
    positions can help to prevent such injuries from
