Health and Safety : Measures

By taking appropriate measures the risk of many computer related health and safety problems can be reduced. Sensible measures for reducing these risks are listed below. Some of them are required by law.

Problem Measures to Reduce Risk
Eye Strain
  • Regular eye tests carried out by an optician will help identify any sight problems so that they can be corrected by glasses. Special glasses may be required for work using a computer monitor.
  • The monitor should not be too close to the user. A distance of 50 to 60cm away is recommended.
  • Reflections on the monitor screen should be avoided by appropriate positioning of the screen and nearby light sources and the use of an anti-glare screen.
  • Room lighting should not be too bright and should be flicker-free. Natural sunlight or high frequency fluorescent tube lighting can achieve this.
  • Regular breaks away from the computer will allow the eyes to refocus at a normal viewing distance.
Wrist
Problems
  • A worker's job should be designed so that there is some variety in the tasks that the worker carries out.
  • Regular breaks where the worker stops typing should be incorporated into the working day. A typical system might include 10 minutes away from the computer every hour.
  • The position of the keyboard, monitor and chair should be adjusted to make working as comfortable as possible.
  • The use of alternative input methods such as voice recognition instead of the keyboard can reduce the amount of typing that has to be done.
  • A careful watch should be kept for early symptoms such as tingling, aching, swelling or numbness in the hands and wrists.
Back and
Neck
Problems
  • Appropriate positioning of the keyboard, monitor and chair together with an upright seating position will reduce the strain on back and neck muscles.
  • Taking regular breaks will provide relief to the muscles which are used to maintain the seated position.
Stress
  • Jobs should be designed so that they incorporate a variety of different activities so that workers do not find their tasks too repetitive.
  • An employee's workload should be achieveable. Giving employees more work than they can hope to complete will produce stress.
  • The user interface of the computer software that is being used should not frustrate the user.
  • An appropriate system for identifying and counselling people who are encountering stress will help to overcome problems which were not avoided.
Electrical
Safety
  • New electrical equipment must comply with legal requirements to ensure that it is safe to use.
  • Installed electrical equipment and wiring must be regularly tested to ensure that it remains safe. Records of these tests must be kept.
  • Employees must be trained in the safe use of electrical equipment.

Many of the suggested measures, such as taking regular breaks away from the computer can help to reduce the risks of several problems at the same time.
