Safety and Comfort 1-1
+D=FJAH Safety and Comfort
WARNING: 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.
