❖
rapid changes in temperature or humidity. Keep the computer
away from sources of temperature change such as air condi-
tioner vents or heaters.
❖
extreme heat, cold or humidity. Operate the computer within a
temperature range of 40 to 95 degrees Fahrenheit (5 to 35
degrees Celsius) and a relative humidity of 20 to 80 percent.
Keep Yourself Comfortable
Strain and stress injuries are becoming more common as people
spend more time using their computers. However, if you use your
computer properly, you can work comfortably all day.
When you cannot place your computer in the best position for
working (on a journey for example) be careful to use it for short
periods only.
Using the computer keyboard incorrectly can result in dis-
comfort and possible injury. If your hands, wrists, and/or
arms bother you while typing, discontinue using the com-
puter and rest. If the discomfort persists, consult a physician.
In addition to the hints provided in the following sections, there
are a number of books available on ergonomics, repetitive strain
injury, and repetitive stress syndrome.
Placement of the Computer
Proper placement of the computer and external devices is impor-
tant to avoid stress-related injuries:
❖
Place the computer on a flat surface, directly in front of you, at
a comfortable height and distance. When you use the key-
board, your arms and hands should be in a relaxed position
with your forearms parallel to the floor. You should be able to
type without twisting your body or neck, and look at the screen
without slouching.
