What are the Risks to people
who regularly use workstations ?
Work Related Upper Limb Disorder (WRULD) ranging from temporary fatigue to chronic soft
tissue injuries eg tendinitis or carpal tunnel
syndrome.
Postural – prolonged static posture and
awkward sitting position eg twisting are known to
cause musculoskeletal problems.
Why should we conduct risk
assessments on workstations ?
Legal – requirements HSWA 1974 and
H&S (DSE) Regs 1992.
Moral – If a risk assessment is conducted
and followed the risks (previous slide) are
reduced significantly.
Financial - Less chance of a person being
off work sick with WRULD or
musculoskeletal disorders.
When assessing a workstation what
would you consider about the
following:
Display Screen
Key Board
Mouse
Software
Desk
Chair
Environment
Display Screen
Adjust brightness & contrast to suit lighting
Screen surface clean
Screen characters sharply focussed ( no
flicker )
Text size – large enough to see clearly
Screen at an appropriate height
Key Board
Correctly placed with adequate space
Symbols legible
Facility to tilt
Wrist support if required
Mouse
Mat free from splits, cracks & fraying
Positioned within reach
Used with wrist straight
Room to support forearm on desk
Software
Appropriate for tasks required
Operators trained where appropriate (eg
SWIFT)
Help facilities
Desk
Adequate space to accommodate
equipment
Space under desk for leg movement
Provision of footrest (where required)
Set to avoid twisting of the spine and neck
Chair
Moveable (casters fitted )
Adjustable in height & tilt
Users forearms – approx. horizontal
Eyes – same height as top of the VDU
Environment
Adequate heating & ventilation
Adequate artificial lighting
Natural lighting –able to restrict (blinds)
Sufficient space
Free of other hazards eg trip hazards
Noise shouldn’t be distracting
Work station set up
Work station set up
1. Eye to screen distance about 500 to 700 mm. When seated correctly
you should just be able to touch the screen with an outstretched
fingertip. If a document holder is used it should be placed at a similar
distance from the eyes and in the same plane as the screen.
2. Screen height and angle should allow comfortable head position
3. Chair providing adjustable seat height and backrest
4. Good lumbar support to maintain ‘S’- shaped spinal curve
Work station set up
5.
No undue pressure on underside of thighs and backs of knees
6.
Foot support adjustable in height if you cannot rest your feet firmly
on the floor
7.
Clearance under desk for thighs and space for postural change
8.
Forearms approximately horizontal.
9.
Minimal upward (extension) or downward (flexion) deviation of
wrists
10. Support for wrists, if needed
