Chapter 1 Safety and Comfort

ÅÅ

ÅWARNING: There may be a risk of serious physical injuries from working at your computer

workstation. Read and follow the recommendations in this section to minimize the risk of injury and to

increase your comfort.

Some studies have suggested that long periods of typing, improper workstation setup,

incorrect work habits, stressful work conditions and relationships, or problems in

your personal health may be linked to injuries. These injuries could include carpal

tunnel syndrome, tendinitis, tenosynovitis, and other musculoskeletal disorders.

The warning signs of these disorders can occur in the hands, wrists, arms, shoulders,

neck, or back, and can include:

◆Numbness, burning, or tingling

◆Soreness, aching, or tenderness

◆Pain, throbbing, or swelling

◆Tightness or stiffness

◆Weakness or coldness

Symptoms may be felt during typing, while using a mouse, or at other times when no

work with the hands is being performed, including during the night when these

symptoms might awaken you. If you experience these symptoms, or any other

persistent or recurring pain or discomfort that you think may be related to using a

computer, you should promptly consult a qualified physician and, if available, your

company’s health and safety department. The earlier a problem is properly diagnosed

and treated, the less chance there is that it will progress to a disabling condition.

The following pages describe proper workstation setup, posture, and health and work

habits for computer users. In addition, this Guide contains product safety information

applicable to all Compaq products.
