Desks
The best way to provide the proper screen and keyboard
heights for all users is to use split level tables or desks that
allow each height to be adjusted independently. This ensures
that almost all users, large and small, can have proper
postures as they work. Any table, desk or stand used for
computer work must be deep enough for both the keyboard
and the monitor to be in front of the worker.
The Canadian Standards Association's Guideline on Office
Ergonomics (CAN/CSA Z412-17) recommends a minimum
of 50 cm. More space may be required for larger monitors,
or less space for flat screens. Keyboard trays and/or monitor
risers may also be used to achieve proper positioning. There
should also be sufficient leg room: 43 cm of horizontal knee
space and 60 cm of toe space.
Document Holders
Computer work often involves entering information from
source documents. These should be located beside the screen
and in the same plane. Alternatively, 'slant board' document
holders position the document between the monitor and the
keyboard, thus minimizing the need to rotate the neck. This
reduces the amount of head and eye movements between the
document and the screen and decreases the risk of muscular
and visual fatigue.
The best way to correctly position documents is to use an
adjustable document holder. Make sure the holder is suitable
for the size and type of documents used in your workplace.
