Safety and Comfort 1
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
◆eakness 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.

2Safety and Comfort
Promoting a Safe and Comfortable Work Environment
Posture, lighting, furniture, work organization, and other work conditions and habits
may affect the way you feel and how well you work. By adjusting your work
environment and personal practices, you may be able to minimize fatigue and
discomfort, and reduce the risk of resulting strains that some scientists believe can
lead to injury.
Important
Choices
If you share a computer with others, readjust the work environment to your needs.
Each time you sit down to work, adjust into your comfort zone.
henever you use a computer, you make choices that can affect your comfort and
potentially your safety. This is true whether you use a full-size keyboard and monitor
on a desk, a notebook computer, or a wireless keyboard on your lap. In every case,
you choose your working posture and your body’s position relative to your keyboard,
pointing device, monitor, remote control, phone, and any reference books and papers.
You may also have some control over lighting and other factors.
Take Action for
Safety and
Comfort
Many factors in our work environment determine whether we work efficiently and in
a manner that promotes good health and safety.
By considering, acting on, and periodically reevaluating the recommendations in this
Section, it is possible to create a safer, more comfortable, healthful, and efficient
work environment.
"NOTE: Some scientists believe that working intensely or for a long time in uncomfortable or unnatural
positions may pose risks such as those mentioned in the warning. The information included in this
Section is designed to help you work more safely by recommending ways to work more comfortably
and effectively.
#HINT: SEL -CHECK: After reviewing the information in this chapter double-check your postures and
habits using the section
Self-Check
on page 24.

Safety and Comfort 3
Key Principles
To promote safety and comfort, follow these principles whenever you use your
computer.
Adjust
Adjust your body position and your work equipment.
There is no one “right” position. Find your comfort
zone, as described in this Section, and when working at
your computer, frequently adjust within this zone.
Move
Vary your tasks so that you can move around; avoid
sitting in one posture all day. Perform tasks that require
walking.
Relax
Build positive relationships at work and home. Relax
and strive to reduce sources of stress. Stay aware of
physical tension such as clenching your muscles and
shrugging your shoulders. Continually release tension.
Take frequent short breaks.
Listen
Listen to your body. Pay attention to any tension,
discomfort, or pain you may feel, and take immediate
action to relieve it.

4Safety and Comfort
Remember
Remember to exercise regularly and maintain general
fitness. Doing this will help your body withstand the
rigors of sedentary work. Respect any medical
conditions you may have or other health factors you
may know of. Adjust your work habits accordingly.
inding Your Comfort Zone
A Range of
Positions
Rather than working in a single posture, find your comfort zone. Your comfort zone
is a range of positions that is generally appropriate and comfortable for your given
work situation.
Vary Your Posture
Depending on your tasks, you may find a range of seated
and standing postures that are comfortable. ithin your
comfort zone, change postures often throughout the day.
Move
Sitting still for long periods can cause discomfort and muscle fatigue. Changing
postures is good for many parts of your body, including your spine, joints, muscles,
and circulatory system.
ithin your comfort zone, change postures often throughout the day. Take frequent
short breaks: stand up, carefully stretch, or walk around. Frequently switch to brief
tasks that require getting up, such as retrieving output from a printer, filing
paperwork, or consulting a colleague down the hall.
If your furniture offers a wide range of adjustments, you might find it comfortable to
switch back and forth between sitting and standing positions.

Safety and Comfort 5
Different Tasks,
Different
Postures
Your choice of posture within your comfort zone may vary with your task. For
example, you may find a reclined posture most comfortable for computer tasks, and a
more upright posture more comfortable for tasks requiring frequent reference to
papers or books.
Organizing Your
Adjustments
The order in which you make various adjustments to your body position and work
area may vary depending on the adjustability of your furniture. For tips on how to
order your adjustments see the section Arranging Your Work Area on page 10.
#HINT: THAT A TERNOON SLUMP: Pay particular attention to adjusting your posture in the afternoon
when you may tend to get fatigued.
HINT: EVERYTHING IS CONNECTED: When you reposition any one part of your body you may need to
adjust other parts as well.
AVOID! ◆Don't sit in one fixed posture all day.
◆Avoid slouching forward.
◆Be sure not to lean back too far.

6Safety and Comfort
eet, Knees, and
Legs
Make sure your feet can rest solidly and comfortably on the floor while sitting. Use
an adjustable work surface and chair that allow your feet to rest firmly on the floor, or
use a footrest. If you use a footrest, be sure it is wide enough to accommodate
different leg positions within your comfort zone.
Providing enough leg room
Be sure you have sufficient space under your work surface for your knees and legs.
Avoid concentrated pressure points along the underside of your thigh near the knee
and the back side of your lower leg. Stretch your legs and vary your leg posture
throughout the day.
RIGHT!
Rest your feet firmly on the floor or a footrest.
WRONG!
Don’t dangle your feet and compress your thighs.
#HINT: WALK: Get up from your desk frequently and take brief walks.
HINT: LEG COM ORT: Vary your leg positions throughout the day.
AVOID! Avoid placing boxes or other items under your desk that limit your leg room. You should be able to pull
yourself all the way up to your desk without interference.

Safety and Comfort 7
Back Use your chair to fully support your body. Distribute your weight evenly and use the
entire seat and backrest to support your body. If your chair has adjustable low back
support, match the contours of the chair’s backrest to the natural curve of your lower
spine.
Getting comfortable
Always make sure your lower back is well-supported. Make sure it feels comfortable
in the position in which you are working.
RIGHT!
Distribute your weight evenly and use the entire seat and
backrest to support your body.
WRONG!
Don’t slouch forward.
#HINT: ADJUST O TEN: If your chair is adjustable experiment with the adjustments to find numerous
comfortable positions then adjust the chair frequently.
AVOID! If you get a new adjustable chair or if you share a chair with someone else don’t assume the settings
are properly set for you.

8Safety and Comfort
orearms,
Wrists, and
Hands
Keep your forearms, wrists, and hands aligned in a straight, neutral position, whether
you are working at a desk or table, or sitting on a couch or bed. Avoid bending or
angling your wrists while typing or using a pointing device.
Don’t anchor your wrists
hen typing, do not anchor or rest your wrists on your work surface, your thighs, or
a palm rest (sometimes called a wrist rest). Resting your palms while typing may be
harmful because it can cause you to bend your wrists back and can apply pressure to
the undersides of your wrists. A palm rest is designed to provide support during
pauses, when you are not typing.
RIGHT!
Hold a straight, neutral wrist position while typing.
WRONG!
Don’t rest your palms on a work surface while typing.
RIGHT!
Hold a straight, neutral wrist position while typing.
WRONG!
Don’t angle your wrists; this may cause unnecessary
strain.

Safety and Comfort 9
#HINT: Split Keyboards
If you find it difficult to type with a straight neutral wrist position you may want to try a split keyboard.
Be aware however that improper setup or posture while using a split keyboard can increase bending
in your wrists. So if you try one set it up properly to align your forearms wrists and hands.
AVOID! Be sure not to rest your wrists on sharp edges.
Shoulders and
Elbows
Adjust your chair height or keyboard height so that your shoulders are relaxed and
your elbows hang comfortably at your sides. Adjust your keyboard slope so that your
wrists are straight.
Checking elbow height
Position your elbows in a zone that is near the height of your keyboard’s home row
(the row that includes the letters G and H). This position allows you to relax your
shoulders. If you have long upper arms, you may find you need to position your
elbows a bit below the height of home row in order to provide enough space under
the work surface for your knees and legs.
RIGHT!
Turn your chair to the side to help determine if your
elbow height is near the height of your keyboard’s
home row.
#HINT: RELAX: Remember to relax particularly in areas where muscle tension often builds such as
your shoulders.
Eyes orking at your computer for long periods can be a visually demanding task and may
cause your eyes to become irritated and fatigued. Therefore, you should give special
attention to vision care, including the following recommendations:
Resting your eyes
Give your eyes frequent breaks. Periodically look away from the monitor and focus
at a distant point. This may also be a good time to stretch, breathe deeply, and relax.

10 Safety and Comfort
Cleaning your monitor and eyeglasses
Keep your display screen and your eyeglasses or contact lenses clean. If you use a
glare-reduction filter, clean it according to the manufacturer’s directions.
Having your eyes examined
To be sure that your vision is adequately corrected, have your eyes examined
regularly by a vision care specialist. Consider having glasses made that are
specifically suited for working with a computer monitor. If you wear bifocals or
trifocals, you may find these special monofocal glasses more comfortable for
computer use. For more information, see Adjusting monitor height for bifocal and
trifocal users on page 12.
#HINT: Eye Comfort
While looking at your monitor and also while resting your eyes remember to blink. This helps keep
your eyes naturally protected and lubricated and helps prevent dryness a common source of
discomfort.
HINT: Eye Break
Give your eyes frequent rests by focusing them on a distant point.
Arranging Your Work Area
You may find a range of monitor heights that allows your head to be balanced
comfortably over your shoulders.
Monitor You will reduce eye strain and muscle fatigue in your neck, shoulders, and upper
back by properly positioning your monitor and adjusting its angle.

Safety and Comfort 11
Positioning the monitor
Place the monitor directly in front of you. To
determine a comfortable viewing distance, stretch
your arm toward the monitor and notice the location
of your knuckles. Place your monitor near that
location. You should be able to clearly see the text on
your monitor.
Adjusting the monitor height
Your monitor position should allow your head to be balanced comfortably over your
shoulders. It should not cause your neck to bend forward uncomfortably or backward
to any degree. You may find it more comfortable to position the monitor so that the
top line of text is just below your eye height. Your eyes should look slightly
downward when viewing the middle of the screen.
Many computer designs allow you to place the monitor on top of the system unit. If
this places the monitor too high, you may want to move the monitor to the desktop.
On the other hand, if the monitor sits on your work surface and you feel any
discomfort in your neck or upper back, the monitor may be too low. In that case, try
using a thick book or a monitor stand to raise the monitor.
Tilting the monitor
Tilt the monitor so that it faces your eyes. In general, the monitor screen and your
face should be parallel to each other. To check for correct monitor tilt, have someone
hold a small mirror in the center of the viewing area. hen sitting in your normal
work posture, you should be able to see your eyes in the mirror.
#HINT: Eye Height
Your eye height will change considerably whether you use a reclining or upright posture or some
posture in between. Remember to adjust your monitor’s height and tilt each time your eye height
changes as you move through your comfort zone.
AVOID! If you look at the monitor more than you look at paper documents avoid placing your monitor to the
side.

12 Safety and Comfort
Adjusting monitor height for bifocal and trifocal users
If you wear bifocals or trifocals, it’s especially important to properly adjust your monitor
height. Avoid tilting your head back to view the screen through the lower portion of your
glasses; this could lead to muscle fatigue in your neck and back. Instead, try lowering
your monitor. You may want to consider using monofocal glasses that are specially made
for computer use.
WRONG!
If you wear bifocals or trifocals, don't position your monitor
so high that you have to tilt your head back to view the
screen.
#HINT: Notebook Viewing
Whenever using a notebook computer for long periods you may find it more comfortable to connect a full-
size monitor. A separate monitor gives you a wider range of viewing distance and height options.
#HINT: Adjusting Brightness and Contrast
Reduce the potential for eye discomfort by using brightness and contrast controls on your monitor to
improve the quality of text and graphics.
Eliminating glare and reflections on your monitor
Take the time to eliminate glare and reflections. To control daylight, use blinds, shades,
or drapes, or try other glare-reducing measures. Use indirect or reduced lighting to avoid
bright spots on your display screen.
If glare is a problem, consider these actions:
◆Move your monitor to a place where glare and bright reflections are eliminated.
◆Turn off or reduce ceiling lights and use task lighting (one or more adjustable lamps)
to illuminate your work.
◆If you cannot control the ceiling lights, try positioning your monitor between rows of
lights instead of directly beneath a row of lights.
◆Attach a glare-reduction filter to your monitor.

Safety and Comfort 13
◆Place a visor on your monitor. This device may be as simple as a piece of cardboard
extending out over the monitor’s top front edge.
◆Avoid tilting or swiveling your display in a way that leads to an uncomfortable head
or upper back posture.
#HINT: Eliminating Glare
Try positioning your monitor so that its side faces the windows.
AVOID!.◆Avoid compromising your posture to compensate for glare or reflections.
◆Try to avoid bright light sources in your field of vision. For example don’t face an uncovered window
during daylight hours.
Keyboard and
Pointing Device
Place your keyboard, mouse, and other input devices, so that you can use them with your
body in a relaxed, comfortable position. In this way, you don’t have to reach or shrug your
shoulders while working.
Positioning the keyboard
Position the keyboard directly in front of you to avoid twisting your neck and torso. This
makes it possible to type with your shoulders relaxed and your upper arms hanging freely
at your sides.
Adjusting the keyboard height and slope
Your elbow height should be near the height of your keyboard’s home row (see illustration
under Shoulders and Elbows on page 9). Adjust your keyboard slope so that your wrists
are straight.
Aligning the mouse and keyboard
hen using a mouse or detached trackball, position the device immediately to the right or
left of your keyboard.
Using a keyboard tray comfortably
If you use a keyboard tray, make sure it is wide enough to accommodate your pointing
device, such as a mouse or trackball. Otherwise, you will probably place the mouse on
your desktop, higher and farther away than the keyboard. This will lead you to stretch
forward repeatedly, and uncomfortably, to reach the mouse.

14 Safety and Comfort
RIGHT!
Position your pointing device immediately to the right or left of your
keyboard.
WRONG!
Don’t position your keyboard and pointing device at different levels
and distances.
Arm Supports
and a Palm Rest
You may find that supports for your forearms or hands allow you to be more relaxed and
comfortable.
Using arm supports
Some chairs and desks provide padded areas for resting your arms. You may find it
comfortable to rest the middle of your forearms on these supports while typing, pointing, or
pausing. Arm supports are properly adjusted when your shoulders are in a comfortable
position and your wrists are straight.
Using a palm rest
A palm rest is designed to provide support during pauses, not during typing or pointing.
hile typing or using a pointing device, keep wrists free to move, not anchored or resting on
a palm rest, the desk, or your thighs.
RIGHT!
You may find that arm supports help you relax your shoulders
and keep your wrists free to move while typing.

Safety and Comfort 15
#HINT: or Pauses Only
Palm rests should only be used during pauses when you are not typing or using your pointing device.
AVOID! Armrests should not cause you to:
◆Shrug or drop your shoulders.
◆Put excessive pressure on your elbows.
◆“Wing” your arms (extend elbows out to the sides).
Papers and
Books
Select a work surface or surfaces that are large enough to hold the computer equipment
and any additional items required for your work. To help minimize eye fatigue, position
any materials to which you frequently refer at about the same viewing distance.
Minimizing your reach
Arrange your frequently used papers, books, or other items to minimize the distance
you reach for them. If you frequently refer to books, papers, and writing materials, and
if you use a keyboard tray, make sure the tray, when extended, doesn’t cause you to lean
forward or reach excessively. This can stress your shoulders and back. If you find that
such stress occurs, you may want to consider a different type of work setup.
Using a document holder
If you use a document holder, position it near the monitor at the same distance, height,
and angle as the monitor. Positioning the holder in this way can increase your neck
comfort as you refer back and forth between your papers and the display screen, by
helping you keep your head balanced over your shoulders.
If your primary task is typing from paper documents, you may find it more comfortable
to place your document holder directly in front of you and your monitor slightly to one
side, or on a slant board between your monitor and keyboard. Consider this option only
if you spend more time looking at the paper than at your monitor.
WRONG!
Don’t arrange your work area in a way that causes you to
repeatedly strain forward to see and reach frequently used
items such as books, papers, or a phone.

16 Safety and Comfort
Phone Cradling your phone between your ear and shoulder may lead to neck, shoulder, and
back discomfort. If you use your phone a lot, try using a headset or positioning your
phone so you pick it up with your non-dominant hand. This frees your dominant hand
for note-taking. hen not in use, place the phone within easy reach.
RIGHT!
Use a headset to free your hands and help you avoid
uncomfortable positions.
WRONG!
Don’t cradle your phone between your ear and shoulder.
