Health and Safety : Risks

Working with a computer system and monitor is not believed to be particularly dangerous. However research has revealed that some types of problem are more common in workers who use computers for long periods than in other workers. The problems that computer users have the highest risk of encountering are identified below.

Problem Explanation
Eye Strain Research suggests that using a computer monitor does not have any negative effects on eyesight in the long term. However there is evidence that computer monitors can cause temporary eye strain. Eye strain can be caused by poor positioning of a monitor, particularly if it is too close to the user, by poor lighting in an office or reflections from a screen. The most common symptom of eye strain is a headache.
Wrist Problems Typing for prolonged periods without a break can result in a Repetitive Strain Injury (RSI) such as tendonitis. RSI occurs when a person is constantly using the same group of muscles. This occurs in the fingers, hands and wrists when a worker types at a keyboard for a long time.
Back and Neck Problems Back and neck problems occur in computer operators because they remain seated in the same position for a substantial part of the working day. Poor location of the keyboard and monitor relative to the worker's chair can increase the risk of back and neck problems.
Stress Stress is a feeling of mental or physical strain or tension. It is a person's natural reaction to being placed under too much pressure at work. Stress can be caused by prolonged periods of concentration which often occur when people use computers. Other factors such as the poor design of a user interface to a computer system or the repetitive nature of some computing tasks can also lead to stress. Workers who view themselves as "slaves" to the computer systems that they use are very likely to encounter stress.
Electrical Safety Computer systems include many electrical devices and a lot of extrernal wiring to connect the different components of the system together. Poorly maintained hardware or wiring could result in an electric shock or fire.

Many measures can be taken to reduce the risk of these problems occuring.
