CHAPTER 2: Setting Up and Getting Started
10
Working safely and comfortably
Before using your computer, follow these general guidelines for setting up a safe and comfortable
work area and avoiding discomfort and strain:
•
Keep hands and arms parallel to the floor.
•
Adjust the screen so it is perpendicular to your line of sight, and the top of the screen is
no higher than eye leve.
•
Place your feet flat on the floor or on a footrest.
•
Keep ventilation openings clear of obstructions.
Reducing eye strain
Sunlight or bright indoor lighting should not reflect on the monitor screen or shine directly into
your eyes.
•
Position the computer desk and screen so you can avoid glare on your screen and light
shining directly into your eyes. Reduce glare by installing shades or curtains on windows,
and by installing a glare screen filter.
•
Use soft, indirect lighting in your work area. Do not use your computer in a dark room.
•
Set paper holders at the same height and distance as the monitor.
•
Avoid focusing your eyes on your computer screen for long periods of time. Every 10 or
15 minutes, look around the room, and try to focus on distant objects.
Setting up your computer desk and chair
When you are setting up your computer desk and chair, make sure that the desk is the appropriate
height and the chair helps you maintain good posture.
•
Select a flat surface for your computer desk.
•
Adjust the height of the computer desk so your hands and arms are positioned parallel to
the floor when you use the keyboard and touchpad. If the desk is not adjustable or is too
tall, consider using an adjustable chair to control your arm’s height above the keyboard.
•
Use an adjustable chair that is comfortable, distributes your weight evenly, and keeps your
body relaxed.
•
Position your chair so the keyboard is at or slightly below the level of your elbow. This
position lets your shoulders relax while you type.
