Ergonomics

What is ergonomics?

Ergonomics is a multi-disciplinary science of adapting human characteristics and capabilities to the work environment to improve human health, performance and optimal productivity. Ergonomics impacts our daily lives and influences the design of tools at work, appliances in our homes, and computer workstations, including monitors, mice, and keyboard and seating.

Ergonomics emphasizes designing the workplace to fit the employee rather than the employee fitting the workplace. The goal of an ergonomic program is to minimize injury and illnesses due to chronic physical and psychological stresses, while maximizing comfort, productivity, and efficiency.

Why is ergonomics important?

"One size fits all" is contrary to ergonomics and is not a practical solution for ergonomic issues. Human work populations vary greatly in physical size and capabilities. Adjustable workstations, office equipment, and several sizes of hand and power tools help employees maintain a neutral posture which can be maintained throughout the day. By adhering to the neutral position, comfort is increased and the potential for physical risk factors are decreased.

Musculoskeletal disorders (MSDs) or repetitive strain injuries are musculoskeletal disorders that result from repeated exposure to physical risk factors. Risk factors affect tendons, ligaments, nerves, muscles and bones. Risk factors in the workplace are caused by sustained awkward postures repetitive motions, using excessive force or compression.

In 2005, the Bureau of labor statistics reported sprains and strains accounted for 41% of all occupational injuries and illnesses involving days away from work. Another 10% of workers had pain (back and other), carpal tunnel syndrome, and tendonitis that resulted in lost time. Many employees experience these conditions and do not lose time from work but suffer pain and discomfort throughout the workday. 

The "neutral posture" is recommended to minimize stress and strain to soft tissues and prevent injury.

How can I get a workstation evaluation?

Evaluations are conducted by a representative from Environmental Health & Safety. It is suggested that employees use ErgoSmart to become familiar with basic workstation design and neutral position before requestion a site evaluation. Employees who are experiencing significant discomfort or have filed a Workers' Compensation claim may bypass the software training and expedite their evaluation request. Direct requests for personal evaluations to Environmental Health & Safety at 480.965.1823 or email ehs@asu.edu.

The ErgoSmart program allows an employee to evaluation their workstation prior to requesting assistance from EH&S. Many employees find the program helpful and need no further assistance. However, this may not be the case when obsolete equipment or chairs are provided. The employer is responsible for replacing chairs, keyboard trays, keyboard, mice and other equipment as needed. If changes to the workstation cannot be achieved without assistance, or if discomfort does not improve after changes, contact EH&S for assistance at 480.965.1823 or email ehs@asu.edu.
