Working with Computers and Monitors
Handheld Devices

This guidance provides information for managers and users on the possible health risks associated with handheld devices and guidance on issuing handhelds to staff.
  • Managers should be aware of the possible health risks such as upper limb disorders associated with excessive or prolonged use of handheld devices like PDAs and the BlackBerry.
  • As handheld devices are not DSE compliant they should only be issued for brief and intermittent use.
  • Handheld devices should not be considered a substitute for a laptop or PC.
  • Health hazards such as upper limb disorders may be linked to excessive and prolonged use of handheld devices.
  • The small, repetitive movements used to manoeuvre controls can cause pain over time.
  • The thumb especially is not designed for dexterity and is particularly susceptible to injury if used excessively in this way.
  • The small screen size may also result in poor posture or visual fatigue.
 
Guidance for managers
  • Managers should carefully consider whether a handheld device is appropriate before issuing one to your staff.
  • Handhelds do NOT comply with DSE Regulations. This means that they should not be used for over an hour at a time.
  • If your staff is likely to use an input device for over an hour at a time or for more than 2 hours in any working day, then a handheld is NOT the right choice. Alternatives such as a laptop wireless card may be required.
  • If your staff is likely to use an input device for over an hour at a time or for more than 2 hours in any working day, then a handheld is NOT the right choice. Alternatives such as a laptop wireless card may be required.
  • Provide your staff with information on possible hazards and advice (see below).
  • Encourage your staff to report problems or concerns.
  • Know what do if any of your staff start experiencing symptoms.  For further information see here.
 
Advice for users
  • Health risks such as upper limb disorders and visual fatigue may be linked to prolonged or excessive use of handhelds.
  • The small, repetitive movements used to manoeuvre controls can cause pain over time. The thumb particularly is not designed for dexterity and may be susceptible to injury if used excessively in this way.
  • The small screen size may also make it more difficult to adopt a good working posture.
  • Keep any inputting brief and intermittent. It should never be used continuously for over an hour or for more than 2 hours in any one day.
  • Take regular breaks. Don't wait until you feel discomfort.
  • Vary the way you input. Try using your fingers, a stylus or even a rubber-tipped pencil rather than your thumb.
  • Watch your posture avoid bending your neck and upper back to look at the screen and if possible support the arm holding the device.
  • Choose a font size that is clearly legible and keep the screen clean.
  • If you experience discomfort which you feel could be related to using a handheld report this to your manager.
