Selecting a place to work
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. Consider the following
when placing your computer.
❖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.
Seating and posture
When using your computer, maintain good posture with your
body relaxed and your weight distributed evenly. Proper seating is
a primary factor in reducing work strain. Some people find a
backless chair more comfortable than a conventional chair.
Whichever type you choose, use the following guidelines to adjust
your chair for maximum computing comfort.
