areas such as: Muscle force required to perform manual tasks Compressive low back disk force when lifting Cardiovascular response when performing heavy labour Perceived maximum load that can be carried, pushed or pulled Areas of knowledge that involved human behaviour and attributes (i.e., decision making process, organization design, human perception relative to design) became known as cognitive ergonomics or human factors. Areas of knowledge that involved physical aspects of the workplace and human abilities such as force required to lift, vibration and reaches became known as industrial ergonomics or ergonomics. The broad group focus and name duality continues at this time. Contributors to ergonomics/human factors concepts include industrial engineers, industrial psychologists, occupational medicine physicians, industrial hygienists, and safety engineers. Professions that use ergonomics/human factors information include architects, occupational therapists, physical therapists, occupational medicine nurses, and insurance loss control specialists. The following points are among the purpose/goals of ergonomics: occupational injury and illness reduction workers' compensation costs containment productivity improvement work quality improvement absenteeism reduction government regulation compliance. The methods by which these goals are obtained involve: evaluation and control of work site risk factors identification and quantification of existing work site risk conditions recommendation of engineering and administrative controls to reduce the identified risk conditions education of management and workers to risk conditions. Workplace DescriptionThe work setting is characterized by an interaction between the following parameters: 1.a worker with attributes of size, strength, range of motion, intellect, education, expectations, and other physical/mental capacities. 2.a work setting comprised of parts, tools, furniture, control/display panel...
