Selecting a place to work

❖Extreme heat, cold, or humidity. Operate the computer within a temperature range of 41 to 95 degrees Fahrenheit (5 to 35 degrees Celsius) and 20 percent to 80 percent non-condensing humidity

Keeping yourself comfortable

Strain and stress injuries are becoming more common as people spend more time using their computers. With a little care and proper use of the equipment, however, you can work comfortably throughout the day.

WARNING: Using the computer keyboard incorrectly may result in discomfort and possible injury. If your hands, wrists, and/or arms bother you while typing, stop using the computer and rest. If the discomfort persists, consult a physician.

This section provides hints on avoiding strain and stress injuries. For more information, consult books on ergonomics, repetitive- strain injury, and repetitive-stress syndrome.

Placement of the computer

Proper placement of the computer and external devices is important to avoid stress-related injuries:

❖Place the computer on a flat surface at a comfortable height and distance. You should be able to type without twisting your torso or neck and look at the screen without slouching.

❖If you use an external monitor, the top of the screen should be no higher than eye level.

❖If you use a paper holder, set it at the same height and distance as the screen.
