There are various health problems associated with the regular use of computers. For this reason employers must be aware of the regulations surrounding computer health and safety;

  • there should be no trailing wires
  • food and drink should not be placed near a machine
  • electrical sockets must not be overloaded
  • there must be adequate space around the machine
  • heating and ventilation must be suitable
  • lighting must be suitable with no glare or reflections
  • benches must be strong enough to support the computers

Many computer users suffer serious back problems. This is probably due to a poor posture or an awkward position while sitting at a computer

Solutions
A fully adjustable chair should avoid poor posture.
Footrests can reduce these problems.
Screens should tilt and turn to a position that avoids awkward movements.
Eyestrain
Eyes can become strained after staring at a computer screen for a long time, particularly if working in bad light, in glare or with a flickering screen.

Solutions
Screen filters can remove a high percentage of the harmful rays emitted from a computer screen.
Use screens that do not flicker.
Take regular breaks – do not work for more than one hour without a break.
Lighting must be suitable and blinds fitted to windows to reduce glare.

Repetitive Strain Injury (RSI)
Repetitive Strain Injury (RSI) is damage to the fingers, wrists and other parts of the body due to repeated movements over a long period of time.

SolutionTo prevent RSI, make sure your posture is correct, use wrist rests and have a five-minute break from typing every hour.
