3. Terminal
An improperly placed monitor can place excessive stress on the neck and upper back.
. The top of the screen should be at your eye level. At this height your head
is balanced with your spine and in its most comfortable position.
. For proper eye care sit 30-60 cm, away from the screen.
4. Desk
The distance between you and yours desk is important in reducing repetitive strain from unnecessary reaching.
. You should be close enough to the desk so that you don't have to reach.
5. Mouse
Discomfort in the arms and shoulders is caused by repeatedly extending the arm when using a poorly placed mouse. This can be compounded by a lack of support for the arm, such as a chair armrest or the work surface itself.
. Forearms should fall relaxed by your side.
. Forearms should extend out in front to form an angle of
approximately 90 degrees at the elbow.
. Hand, wrist and forearm should be in straight alignment.
. If at all possible, your forearms should rest on a support such as a
chair armrest or the work surface
. Move the mouse with your arm, not your wrist.
. The location of your mouse pad is very important. With your
upper arm relaxed and at 90 degree angle at the elbow, place the
pad and mouse so that your hand falls naturally on the mouse
when it is in the lower right hand corner of the pad. For left-handed
users, the lower left hand corner.
6. Breaks
Computer operators should take a 15 minute break after every 2 hours of continuous work. To be most effective, you must take this break before the onset of fatigue rather than after fatigue has set in. Stretching during these periods will help reduce muscle tension.
7. Copy Holder and wrist rest
A copy holder will bring your work up to eye level reducing neck tension, and a wrist rest will help keep your wrists in a neutral position reducing muscle strain.
8. Headset
A headset will alleviate holding the receiver between your ear and shoulder while trying to talk on the phone and perform other tasks. This will alleviative neck stiffness and neck "kinks." A headset will free your hands and allow you to perform writing or computer tasks.
