INTRODUCTION TO ASYCUDA++ Ó UNCTAD - SITE (V1.15) 1.17 Potential Radiation danger in Pregnancy There is little evidence to support fears of damage to mother or child through radiation. It is possible that problems could arise due to pregnant women sitting still for long periods at a terminal. Short periods  away  from  the  terminal  should  be  allowed.  However,  many  governments  allow  pregnant women   the   right   not   to   work   with   VDUs.   Computers   can   themselves   be   affected   by   outside radiation and radio frequency transmissions and should not be sited near to any such sources or lightning conductors. Furniture Workstation furniture should be fully adjustable to encourage correct posture and thus reduce the pressures that can cause operator fatigue or physical strain. Noise Printing  equipment  can  generate  excessive  noise  that  should  be  reduced  by  acoustic  hoods  for printers,  particularly  dot-matrix  type.  Laser  printers  should  be  used  where  possible  to  minimise noise and increase productivity. Stress Can result from ·     Boredom, weariness, environmental conditions, office layout etc. ·     Worry about responsibility ·     Bad posture ·     Regular rest periods away from the VDU are recommended. Visual Fatigue and Eyestrain ·     Can be dangerous to users of certain medication; ·     Caused by glare, reflection, lack of contrast; ·     Site VDUs at right angles to the main light; ·     Strip lights can interfere with screen displays; ·     VDU angle, brightness and contract should be adjustable; ·     Screen design of applications is important; ·     Eyesight checks may be needed. Posture ·     Adjustable seating and computer furniture is essential. Additional Safety concerns ·     Screen flicker may affect epileptics who should seek medical advice if uncertain; ·     Good cable management is essential to prevent accidents to staff and damage to equipment; ·     Equipment must be properly sited; ·     Proper maintenance of equipment, cables and connections is essential; ·     There must be means to isolate power supply; ·     Fire extinguishers should be properly sited and marked.
