Working safely
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 mouse. If the desk is not
adjustable or is too tall, consider using a keyboard drawer.
■
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.
■
Adjust the chair height, adjust the forward tilt of the seat, or use a footrest to
distribute your weight evenly on the chair and relieve pressure on the back of your
thighs.
■ Adjust the back of the chair so it supports the lower curve of your spine. You can
use a pillow or cushion to provide extra back support.
Setting up your computer and computer accessories
■
Set up the monitor so the top is no higher than eye level, the monitor controls
are within reach, and the screen is tilted to be perpendicular to your line of sight.
■
Place your keyboard and mouse at a comfortable distance. You should be able to
reach them without stretching.
■ Set paper holders at the same height and distance as the monitor.
Sitting at your computer
■
Avoid bending, arching, or angling your wrists. Make sure that they are in a relaxed
position when you type.
■
Do not slouch forward or lean far back. Sit with your back straight so your knees,
hips, and elbows form right angles when you work.
■
Take breaks to stand and stretch your legs.
■ Avoid twisting your torso or neck.
