Working in Comfort

Thank you for selecting HP computing equipment. To optimize your comfort and productivity, it is important that you set up your work area correctly and use your HP equipment properly. With that in mind, we have developed some set-up and use recommendations for you to follow based on established ergonomic principles.

4 Working in Comfort

Improper and prolonged use of keyboards and input devices are among those tasks that have been associated with repetitive strain injury (RSI) to soft tissues in the hands and arms. If you experience discomfort or pain while using any computing equipment, discontinue use immediately and consult your physician as soon as possible. In addition to the information on RSI given in this chapter, you may also consult the online version of Working in Comfort preloaded on the hard disk of the your HP computing equipment, or visit HP’s Working in Comfort web site at:

http://www.hp.com/ergo/.

About Repetitive Strain Injury

Because your comfort and safety are our primary concern, we strongly recommend that you use HP computing equipment in accordance with established ergonomic principles and recommendations. Scientific literature suggests that there may be a relationship between injury to soft tissues—especially in the hands and arms—and prolonged improper use of keyboards or other equipment requiring repeated motions of the hands and forearms. This literature also suggests that there are many other risk factors that may increase the chance of such injury, commonly called Repetitive Strain Injury.

What is RSI? Repetitive Strain Injury (RSI—also known as cumulative trauma

disorder or repetitive motion injury) is a type of injury where soft tissues in the body, such as muscles, nerves, or tendons, become irritated or inflamed. RSI has been a reported problem for those who perform repetitive tasks such as assembly line work, meatpacking, sewing, playing musical instruments, and computer work. RSI also has been observed in those who frequently engage in activities such as carpentry, knitting, housework, gardening, tennis, windsurfing and lifting children.

What causes RSI? The specific causes of RSI have not been established. Nevertheless, the

incidence of RSI has been associated with a variety of risk factors, including:

Too many uninterrupted repetitions of an activity or motion.

•

Performing an activity in an awkward or unnatural posture.

•

Maintaining static posture for prolonged periods.

•

Failing to take frequent short breaks.

•

Other environmental and psychosocial factors.

•

52 English

4 Working in Comfort

In addition, there have been reports associating the occurrence of RSI with the use of computer keyboards, mice, and other input devices. Also, certain medical conditions, such as rheumatoid arthritis, obesity and diabetes, may predispose some people to this type of injury.

What can I do to avoid RSI?

Some people who use computers may experience physical discomfort during their use. This discomfort may be a symptom of a repetitive strain injury. Properly setting up and using computing equipment can help to minimize your chances of experiencing this discomfort. Welldesigned and properly adjusted equipment alone may not be sufficient to eliminate all potential problems. Maintaining good posture and positioning when working on computers also has a significant bearing on your comfort.

What if I experience discomfort?

If you are experiencing any discomfort, seek professional medical advice immediately. Typically, the earlier a problem is diagnosed and treated, the easier it is to resolve.

Preparing Your Work Environment

When using HP computing equipment, it is important that your work environment contribute to your comfort and productivity.

Your Chair It's very important that your chair provides a comfortable sitting

position and offers the following features:

• A stable base, such as five legs with casters.

Make sure the casters are designed for the type of floor you have in your workspace, whether it is bare or carpeted.

• A height- and tilt-adjustment feature.

It should be easy to adjust your chair height from 40 cm to 52 cm (15.5 inches to 20.5 inches) as measured from the top of the seat pan to the floor. If you are much taller or shorter than average, you may need a chair that can be adjusted beyond this range. Adjust your chair so that the work surface or keyboard tray is at elbow height and your feet are flat on the floor with your knees slightly bent below your hips. Ideally, the seat pan should be able to tilt both forward (minimum of 5 degrees) and backward (minimum of 10 degrees). If the chair has an adjustable seat pan, inclining the seat slightly forward will transfer some of the pressure from the spine to the thighs and feet. This will relieve pressure on your back.

English 53

4 Working in Comfort

• A curved seat edge.

The front of the seat should be curved and

finished in a “waterfall” edge.

• An adjustable back support

in both height and forward and backward tilt. It is important that the backrest correctly supports the lower part, or lumbar curve, of the back.

• A freely rotating swivel

• Fully adjustable and padded armrests.

so you can move easily from side-to-side.

The chair arms should not interfere with adjusting the chair or moving it close to your work surface.

Seat Back Tilt

Seat Back Height

Seat Pan Tilt 5°-10°

Seat Pan Height 40-52 cm

Your Work Surface Ideally, you should be able to adjust the height of your work surface.

A simple way to ensure your work surface is at the correct height is to first adjust the height of the seat-pan of your chair. With your chair properly adjusted and your feet firmly on the floor, adjust the work surface height until your forearms are parallel to the floor when you have your fingers on the keyboard or other input device.

Your Work Posture Sitting in one position for long periods can be uncomfortable. To

minimize the potential for physical discomfort or injury, it's important that you maintain proper posture.

54 English

4 Working in Comfort

• Back

- While sitting at your work surface, make sure your back is supported by the chair's backrest in an erect position or angled slightly backwards.

• Arms

- Your arms should be relaxed and loose, elbows close to your

sides, with forearms and hands approximately parallel to the floor.

• Wrists

- Your wrists should be as straight as possible while using the keyboard, mouse or trackball. They should not be bent sideways, or more than 10 degrees up or down.

• Legs

- Your thighs should be horizontal or angled slightly downward. Your lower legs should be near a right angle to your thighs. Your feet should rest flat on the floor. If necessary, use a footrest, but double check that you have your seat height adjusted correctly before getting a footrest.

• Head

- Your head should be upright or tilted slightly forward. Avoid

working with your head or trunk twisted.

• Overall

- Change your position frequently and take regular breaks to

avoid fatigue.

Setting Up Your HP Computing Equipment

Make sure that all the elements of your HP computer system—monitor, document holder, keyboard, mice and other input devices, and headphones and speakers—are optimally arranged and adjusted to meet your personal requirements. The recommendations that follow will help you achieve this.

English 55

4 Working in Comfort

Your HP Monitor It is important that your monitor screen be clean and positioned

correctly to improve readability and help you work comfortably. Glare, high contrast, reflections, dirt and dust will interfere with what you see on the screen. The recommendations that follow can help you achieve a comfortable arrangement.

The top of your monitor screen should be at or slightly below eye

•

level. Most HP monitors come with a tilt-and-swivel feature that makes it easy to adjust the screen position.

To avoid obscuring your view, the screen should be positioned

•

perpendicular to your line of sight; that is, straight on.

To avoid glare or reflection, try to position the monitor so the screen

•

is at a right angle to your window rather than in front of it. If reflection or glare persists, tilting the screen forward may help.

Maintain a comfortable viewing distance to the screen. Most people

•

prefer a viewing distance of approximately 46 to 76 cm (18 to 30 inches), depending on monitor size. Character size and the amount of space available on the work surface can affect this distance.

Text should be easy to read. To help ease eyestrain, adjust text

•

attributes such as character size, spacing, and color. In addition, you will need to use the controls provided with your monitor to adjust the visual settings so that contrast and brightness levels are comfortable for you. High contrast and low brightness is usually the preferable combination.

The monitor should be free from flicker. If the image on your screen

•

is not stable, the monitor may require repair or adjustment.

When possible, use a program that has a simple user interface, such

•

as easily identifiable icons and pull-down menus. Also, screen information should be displayed in a structured and well-organized way.

56 English

4 Working in Comfort

Monitor Use Specifications

When viewing your monitor, your head should not be tilted more

•

than 15 degrees forward.

You should not have to look up more than 5 degrees above horizontal

•

or down more than 30 degrees below horizontal for normal work tasks, such as typing or reading.

Document Holders When keying in data from a hard-copy document, placing it in a

document holder rather than on a flat surface will make it easier to read. The following recommendations should be observed when using a document holder:

The document holder should be at approximately the same height

•

and distance from your eyes as the screen, and as close to the monitor as possible to prevent neck twisting. Some users prefer a document holder mounted to the monitor while others prefer the document holder positioned between the screen and keyboard.

If the primary task is to view documents rather than using the

•

monitor, the document holder may be placed directly in front of the keyboard with the monitor slightly to the side.

To help reduce stress on your neck and prevent eye fatigue, try to

•

minimize the movement of your head and eyes while using a document holder.

Your HP Keyboard

Keyboard Slope

Thigh Clearance

≥

Keyboard Height 64-76 cm

6cm

The proper positioning and use of your HP keyboard is important when using HP computing equipment. Be sure to observe the following recommendations to optimize your comfort and safety:

We recommend you place your keyboard in front of the screen or

•

document holder, whichever is viewed the most. Your HP keyboard has long cables so you can place it in the position that is most comfortable for you while you are using your system.

Because HP keyboards vary in depth, you'll want to be sure that your

•

work surface or keyboard tray has sufficient room to accommodate your model. The keyboard tray should be wide enough to hold both the keyboard and mouse or trackball: 66 to 71 cm (26 to 28 inches).

Your HP keyboard may have a kickstand that can be opened or closed

•

to raise or lower the keyboard angle. If you are in the correct sitting position with your elbows at about the same level as the work surface, you may not need to use it. However, if your elbows are below the work surface, you may wish to use the kickstand to raise the back of the keyboard.

An adjustable keyboard tray may be useful if you cannot adjust your

•

chair or work surface to the proper height for typing. It should adjust in height from 64 to 76 cm (25 to 30 inches) above the floor and tilt forward and backward to help you find the most comfortable position. Note that research has shown that there may be less muscle tension in shoulders and forearms with the keyboard tilted away from you.

58 English

4 Working in Comfort

When using your HP keyboard, remember it takes very little pressure

•

or force from your fingers to activate the keys. Improper typing style—the use of too much force—can place unnecessary stress on the tendons and muscles in your hands, wrists, and forearms.

Make sure that your hands are in a neutral position when you use

•

your keyboard. This means that your forearms, wrists, and hands should be in a straight line.

The keyboard has a low profile to help prevent excessive bending of

•

your wrists while typing. Literature suggests that you should not bend your wrists sideways or more than 10 degrees up or down. Keep your wrists straight by moving your entire hand and forearm over to use the function keys or numeric keypad.

You may use a palm rest to help keep your hands and wrists in a

•

comfortable and neutral position when you are not typing. Some HP keyboards come with an integrated palm rest. If you use a palm rest, see that it is rounded and padded, and flush in height with the front edge of the keyboard. Note that your palms—not your wrists— should rest on the palm rest. If you don't have a palm rest, try not to rest your wrists on a sharp edge, such as a work surface edge.

Mice and Other Input Devices

Various aspects of using mice and other input devices may increase your risk of discomfort or injury. Observing the following recommendations may reduce that risk:

As with the keyboard, try to keep your hand, wrist and forearm in a

•

neutral position while using your mouse or other input device.

When using a stylus or light pen with a graphics tablet, don't grip the

•

stylus tightly. Keep your hand and fingers relaxed and try to maintain a neutral posture in your hand, wrist and forearm.

English 59

4 Working in Comfort

•

If you use your thumb to rotate the ball on a trackball or spaceball, keep it in a relaxed, natural shape, and maintain a neutral posture in your hand, wrist and forearm.

Hold the mouse gently by draping your fingers over it. Keep your

•

hand relaxed and fingers loose. Do not grip the mouse tightly.

It takes very little pressure or force from your fingers to activate the

•

buttons or scroll wheel on your mouse, scrolling mouse, trackball or other input device. Using too much force can place unnecessary stress on the tendons and muscles in your hands, wrists and forearms.

If you are using a scrolling mouse, be sure to keep your fingers and

•

hand in a relaxed, neutral position when activating the scroll wheel. Also, this type of mouse features software that can minimize the number of mouse movements or button clicks.

When using a mouse, trackball, stylus and graphics tablet, or other

•

input device, position it as close to the keyboard as possible, and keep it at the same level so you do not have to stretch while using it.

WARNING FOR HEADPHONES & SPEAKERS

Use a good quality mouse pad to enable the mouse to work most

•

effectively and reduce unnecessary hand and wrist movements.

Be sure to keep your mouse and trackball clean. Regular removal of

•

accumulated dust and dirt helps ensure proper tracking and reduces unnecessary hand and wrist motions.

If your PC is multimedia or if you add a sound card to your PC, always turn the volume down before connecting headphones or speakers, to avoid discomfort from unexpected noise or static. Listening to loud sounds for prolonged periods of time may permanently damage your hearing. Before putting on headphones, place them around your neck and turn the volume down. When you put on the headphones, slowly increase the volume until you find a comfortable listening level. When you can hear comfortably and clearly, without distortion, leave the volume control in that position.

Keyboard Slope

Thigh Clearance

≥

6cm

• Work Surface Height

Keyboard Height 64-76 cm

- Adjust either your seat height, work surface

Document Holder

or both, to position the work surface at approximately elbow height.

• Work Surface Arrangement

- Make sure frequently used equipment is within easy reach. For example, if you are primarily using the keyboard, place it directly in front of you, not to the side. If you are primarily using the mouse, place it in front of your hand or arm. If you are using both a mouse and keyboard, place them both at the same work surface height and close together. If a palm rest is used, the height should be flush with the front edge of the keyboard. Other items, such as your telephone or notepad, also should be considered.

• Monitor

- Place your monitor so that the top of the screen is at, or

slightly below, eye level (up to 15 degrees).

• Head

- Do not tilt your head forward by more than 15 degrees, and

try not to turn your head toward the side.

• Back

- While sitting at your work surface, make sure your back is supported by the chair's backrest in an erect position or angled slightly backwards.

• Arms

- Make sure your arms and elbows are relaxed and loose, with your upper arm perpendicular to the floor or slightly forward. Keep your forearms and hands approximately parallel with the floor with elbows bent between 70 and 115 degrees. Keep your elbows close to your sides (less than 20 degrees away from your body).

English 61

4 Working in Comfort

Overall

• Legs

- Your thighs should be horizontal or angled slightly downward. Your lower legs should be near a right angle to your thighs. Make sure there is sufficient room under the work surface for your legs.

• Feet

- If after adjusting your chair you cannot rest your feet comfortably on the floor, use a footrest, preferably one that can be adjusted in height and angle.

Look away from the screen from time-to-time to help reduce

•

eyestrain. Focus on distant objects briefly, and blink periodically to lubricate your eyes. You also should have your eyes checked on a regular basis and ensure your eyeglass prescription is suitable for working on a monitor screen.

Remember to occasionally shift position and move your body.

•

Keeping your body in one position for long periods is unnatural and stressful. When prolonged work is required, take frequent short breaks. As a rule of thumb, a five or ten minute break every hour is a good idea. Short frequent breaks are more beneficial than longer less frequent breaks. Data show that people who work for long periods of time without a break may be more prone to injury.

Changing tasks frequently will help prevent muscle stiffness.

•

Examples: alternating between keyboarding, reading, writing, filing, and moving around in your work environment, helps you maintain a relaxed posture. Occasionally stretch the muscles in your hands, arms, shoulders, neck and back. You should stretch at least as often as you take brief task breaks—at least once every hour.

Discomfort may be alleviated by using alternative ergonomic designs

•

and accessories such as ergonomically personalized chairs, palm rests, keyboard trays, alternative input devices, prescription eyeglasses, anti-glare screens, and more. Seek additional information from the sources available to you, including your employer, doctor, local office supply store, and the Information Sources listed in the online version of Working in Comfort, preloaded on the hard disk of your HP computing equipment.
