A Sensible work practices are an important factor in the prevention of muscular
fatigue; discomfort or pain in the arms, neck, hands or back; or eye strain which can be
associated with constant or regular work at a keyboard and visual display unit (VDU).
B It is vital that the employer pays attention to the physical setting such as
workplace design, the office environment, and placement of monitors as well as the
organisation of the work and individual work habits. Operators must be able to recognise
work-related health problems and be given the opportunity to participate in the
management of these. Operators should take note of and follow the preventive
measures outlined below.
C The typist must be comfortably accommodated in a chair that is adjustable for
height with a back rest that is also easily adjustable both for angle and height. The back
rest and sitting ledge (with a curved edge) should preferably be cloth-covered to avoid
excessive perspiration.
D When the keyboard operator is working from a paper file or manuscript, it should
be at the same distance from the eyes as the screen. The most convenient position can
be found by using some sort of holder. Individual arrangement will vary according to
whether the operator spends more time looking at the VDU or the paper – whichever the
eyes are focused on for the majority of time should be put directly in front of the
operator.
E While keying, it is advisable to have frequent but short pauses of around thirty to
sixty seconds to proofread. When doing this, relax your hands. After you have been
keying for sixty minutes, you should have a ten minute change of activity. During this
spell it is important that you do not remain seated but stand up or walk around. This
period could be profitably used to do filing or collect and deliver documents.
F Generally, the best position for a VDU is at right angles to the window. If this is
not possible then glare from the window can be controlled by blinds, curtains or movable
screens. Keep the face of the VDU vertical to avoid glare from overhead lighting.
G Unsatisfactory work practices or working conditions may result in aches or pain.
Symptoms should be reported to your supervisor early on so that the cause of the
trouble can be corrected and the operator should seek medical attention.
