Proper Computer Work Positions Checklist

To minimize fatigue among workers at computers:

• The feet should be placed flat on the floor or on a footrest with the lower legs approximately vertical.
• The thighs should be horizontal with the weight taken in the buttocks. They should not be compressed, especially behind the knees, as this restricts blood flow to the lower legs.
• The trunk should be vertical and the body weight on the spine should be supported by a backrest at the lumbar region.
• The upper arms should hang from the shoulder joint comfortable straight, with the forearms positioned at less than 90 degrees taking the load in the elbow joints, not the upper arm.
• The preferred wrist position is neutral with no deviation up, down, or to the side.
• The head should be inclined slightly downward.
• The National Institute of Occupational Safety and Health recommends a 15-minute break every two hours of continuous computer use to relieve eye and muscular fatigue and a 15-minute break every hour for particularly demanding computer use. This break could be used to do other aspects of the job, such as copying and filing.
