• In general – change your position frequently (around every 20-30 minutes)
and take regular breaks to avoid tiredness.
• Back – when sitting at your workstation, your back must be supported by your
chair’s backrest, which must be upright or angled slightly back.
• Arms – your arms and elbows should be relaxed and loose. Your elbows should
be close to your body. Hold your forearms and hands roughly parallel to the
fl oor.
• Wrists – when working with the keyboard, mouse or trackball, your wrists
should be stretched out and not bent at an angle of more than 10°, where pos-
sible.
Make sure that your wrists are not resting on the table edge itself.
• Legs – your thighs should be horizontal or angled slightly down. Your lower
legs should form an angle with your thighs of approximately 90°. Your feet
should be resting fl at on the fl oor. Use a foot rest if you need one, but fi rst make
sure that your seat height has been adjusted correctly.
• Head – your head should be upright or bent very slightly forward. Do not work
with your head or upper body twisted.
As you work, the top edge of the monitor should be at eye level or very slightly
lower.
The distance between the monitor and the person viewing it depends on indi-
vidual requirements. Distances between 50 and 60cm are commonly used.
