Unit 8: Safety and security
Health aspects: All computer systems have at least tiltable and anti-glass screens, adjustable chairs and foot supports, suitable lightning and uncluttered work stations as well as frequent breaks and frequent eye tests
Back and neck problems/strain caused by sitting in front of a monitor for long periods in the same position. It could be eliminated by using foot rests to reduce posture problems and use fully adjustable chair to give the correct posture.
Repetitive strain injury. It is when fingers and wrists are damaged because of continuous use of a keyboard and repetitive clicking of mouse buttons. It could be minimised by using ergonomic keyboards and take regular breaks (every 30 minutes) and do some exercise during that break (stretching arms for example.
Eyestrain caused by staring at a computer screen too long or having incorrect lightning in the room. Ways to eliminating it is to change to LCD screens if you are currently using CRT screens where there is less flicker in LCD and try focusing on a point that is certain distance away
Headaches caused by screen reflections and flickering screens. It could be minimized by have an eye test regularly and use window blinds to cut out reflections

Electrocution. It could be minimised by checking equipment on a regular basis, not placing any drinks near computers and check insulation on wires regularly
Trailing wires which cause tripping. Using cable ducts and wireless connections are way to minimise tripping to happen
Heavy equipment falling and causing injury. This could be eliminated by using strong and large desks or table to support hardware as well as so the hardware isn't really close to the edge where it can fall off
