Aims
  • The aim of this presentation is
  • To explain why health problems can occur from
    using DSE
  • To teach you how to set up your workstation
    properly
  • To provide you with 10 top tips for working
    safely with DSE

3
Before we go on..
  • DSE stands for Display Screen Equipment
  • DSE is your computer workstation and it includes
  • Your chair
  • Your desk
  • Your computer
  • Accessories on your Desk

Whats the point of this?
  • I am only watching this presentation because my
    employers asked me to
  • I dont have any problems when working at my PC,
    so this is a waste of time
  • I have no problems but I am interested in my
    health
  • I am concerned about working safely with DSE and
    I hope to learn more.

I hope you agree with point 4 !

Section 1 of 3 Health Effects
6
Health Effects (1)
  • Look at the skeleton in the picture
  • Have a guess at how many medical conditions can
    be caused by working with DSE (click on the
    buttons below).

Health Effects (2)
  • The answer is at least 17.
  • If you find that alarming, then you need to take
    this presentation seriously.
  • How many of the conditions have you heard of?
  • The general term for health problems caused by a
    computer is Repetitive Strain Injury or RSI

8
What Causes RSI?
  • These conditions are caused by excess repetition
    or tension in the joints and muscles.

FACT Did you know that there are nearly 700
muscles in the human body?
9
Test Yourself..
  • Take a 1kg bag of sugar and hold it out at arms
    length in front of your face. Initially this
    feels easy, but soon you will start to feel an
    ache in your arm muscles. The ache starts because
    the constant contraction of the muscle reduces
    the blood flow through the muscles (think of
    squeezing water out of a sponge), the muscles are
    starved of oxygen and start to hurt.
  • Now repeat the exercise, but continue to hold the
    weight for longer not surprisingly the pain
    will get worse, but most importantly it will take
    longer for the ache to resolve.
  • When working with DSE at a workstation, the same
    effect takes place such as in the arms,
    shoulders, back, legs and neck.

10
Prevention is Better than Cure
RSI is a progressive condition that can be
divided into three broad stages, although the
symptoms of sufferers do not always neatly fit
into these categories.
  • Stage 1 (mild) Pain, aching and tiredness of
    the wrists, arms, shoulders, neck or legs during
    work, which improves over night. This stage may
    last weeks or months and is reversible.
  • Stage 2 (moderate) Recurrent pain, aching and
    tiredness occur earlier in the working day,
    persist at night and may disturb sleep. This
    stage may last several months
  • Stage 3 (severe) Pain, aching, weakness and
    fatigue are experienced even when a person is
    resting completely. Sleep is often disturbed and
    the sufferer may be unable to carry out light
    tasks at home or work. This stage may last for
    months or years. Sometimes it is irreversible
    and the person never gets back full use of the
    affected part of the body.

11
Am I at Risk ?
  • It is fully possible to use a computer as a
    regular part of your job without ever developing
    RSI.
  • For this to be true you need to do the following
  • Set up your workstation so that it is comfortable
    for you.
  • Take regular breaks throughout the day. 5 minutes
    for every ½ hr of computer use.
  • Lead a healthy and active lifestyle.
  • Enjoy a balanced diet and drink lots of fresh
    water
  • Remember, the human body is not designed to be
    static for long periods. It is suited to being
    active. Not suited to long periods of sitting
    down such as in the car, at work and at home on
    the sofa.

12
Section 2 of 3 Workstation Setup
13
Workstation Setup (1)
  • Now that you have learned about the risks from
    using DSE equipment, we will look at how to set
    up a workstation correctly.
  • By following the guidance in this section you
    will greatly reduce the risk of injury.

14
Bad workstation setup.
  • Spot as many problems as you can with Helens
    workstation

15
Bad workstation setup.
Exhaust fan from nearby PC, can be noisy and blow
out hot air towards the user.
Sunlight shining through blinds. Can cause glare
on the screen
Possibility of Trapped Cables
Computer at an angle on the desk. User needs to
twist her body.
Both elbows not supported
Desk too small.
No back support. Not leaning back on the chair
Arm rest set too high. Unable to move chair
under the desk.

16
Correct Workstation Setup
  • Often people sit down at a desk and dont even
    think of rearranging it. Objects (e.g. phone)
    are left on the desk the way they found them.
  • This is what you need if you work at the
    computer
  • Screen directly in front of you, not at angle so
    you have to twist your neck.
  • A chair that supports your lower back
  • A desk that is large strong enough to support
    all the equipment
  • A monitor (screen) at a comfortable height. As a
    general rule of thumb, your eyes should be level
    with the top of the monitor.
  • Good quality equipment

17
Setting up the chair
  • CORRECT SITTING POSTURE
  • Sitting height must be adjusted to allow an angle
    of 90o between the thighs and lower legs.
  • The backrest must be in a position where it gives
    effective support to the lumbar region (lower
    back).
  • The seat area should be used fully. You should
    not be sat on the edge of your chair.
  • Not all chairs are easy to setup. Ask your
    Health and Safety Officer for help if you need it.

18
Bad Seating Posture
  • Reasons
  • Seat height is to high.
  • Backrest is to high.
  • No contact with the backrest.
  • Sitting too far forward in the seat.
  • Consequences
  • back ache!

19
Correct Workstation Setup
  • The right lighting can reduce eyestrain, neck
    strain and headaches. Sunlight is the best light,
    but make sure it doesn't create glare on your
    computer screen.
  • The proper desk will let you find the perfect
    working position. It should be deep enough to
    support your arms when you work at the computer.
  • Place your computer screen at eye-level or just
    below. For optimal comfort, set it about 45 cm
    (18 in.) from your face.
  • Sit up straight in your chair. Keep your feet
    flat on the floor and your knees level with your
    thighs.
  • Choose an office chair that lets you tilt forward
    to reach objects in front of you and backward to
    stretch your arms when you're tired.
  • When you type, hold your fingers, wrists and
    lower arms in a straight line from your keyboard.
  • Keep equipment that you use a lot, like your
    telephone and computer keyboard, within a
    distance of about 75 cm (30 in.) Keep other
    equipment farther away. This encourages you to
    change positions during the day.
  • Keep a bottle of water on your desk and drink
    regularly from it.

Section 3 of 3 Ten Top Tips
21
10 Top Tips
  • Set up your workstation so that it is comfortable
    for you. This means adjusting your chair and
    rearranging your desk.
  • Take regular breaks throughout the day. 5 minutes
    for every half-hour of computer use.
  • Take regular micropauses. Every 10 minutes leave
    the keyboard and mouse alone for 30 seconds.
  • Lead a healthy and active lifestyle. Play sport.
  • Enjoy a balanced diet and drink lots of fresh
    water.

22
10 Top Tips (cont.)
  • In your free time undertake hobbies that relax
    you and let you unwind.
  • Reduce the amount of time you use a computer by
    only using it when you need to. Rather than
    sending someone an email, phone them instead.
  • Learn keyboard shortcuts for common commands to
    help you reduce the amount of time you use the
    mouse
  • Get an eye test. Tell your optician that you
    work with a computer.
  • If you have any symptoms of RSI, then tell your
    employer immediately

Quiz
24
Question 1 of 7
  • What does RSI stand for?
  • Reduced Static Injury
  • Repetitive Stress Injury
  • Repetitive Strain Injury

25
Question 2 of 7
  • What is the best layout for a workstation?
  • Monitor (screen) on the corner of the desk so
    that I have to twist to see it. I put it there so
    I will have lots of space on my desk
  • I leave all items arranged/adjusted however I
    found them
  • All items within my easy reach. Screen directly
    in front of me, and my chair at the right height
    so that I am comfortable.

26
Question 3 of 7
  • There is glare on your screen, what do you do?
  • Turn up the brightness on the screen to
    compensate for the glare
  • Do nothing, its only a problem at certain times
    of the day when it is really sunny outside. I
    can put up with that.
  • Reposition my desk, or adjust my monitor so that
    it is not affected by the glare. I will also ask
    for blinds to be fitted to the windows.

27
Question 4 of 7
  • What is the best height for your chair?
  • Chair adjusted so that my feet dont touch the
    floor and are free to swing
  • Set as low as possible so that my posterior takes
    most of the weight of my body.
  • Adjusted so that there is a 90o angle between my
    lower leg and my thigh.

28
Question 5 of 7
  • Your open-plan office is too warm, what do you
    do?
  • Get a desk fan and point it at my face. Wear
    loose fitting clothing.
  • Moan constantly and hope someone does something
    about it.
  • Ask other people around me to see what they
    think. We can come to a consensus and ask the
    person in charge of the office to adjust the
    temperature.
