Health and Safety using ICT

  1. 1. Health and Safety Using ICT
  2. 2. Ergonomics <ul><li>Intended to maximize productivity (work completed) by minimizing user tiredness and discomfort in the workplace. </li></ul><ul><li>Ensures positional safety. </li></ul>
  3. 3. Desk <ul><li>The desk must be: </li></ul><ul><ul><li>Large enough to allow the monitors, keyboard etc to be correctly positioned. </li></ul></ul><ul><ul><li>Matte surface, to avoid reflective glare. </li></ul></ul><ul><ul><li>Low enough to allow you to keep your forearms horizontal and high enough to allow your thighs underneath it. </li></ul></ul><ul><ul><li>Elbows should be at an angle of at least 90 degrees when sitting at it. </li></ul></ul>
  4. 4. Chair <ul><li>The chair must be: </li></ul><ul><ul><li>High enough to allow you to sit comfortably over the keyboard. </li></ul></ul><ul><ul><li>It should swivel: five castors will ensure that it is stable. </li></ul></ul><ul><ul><li>Must be adjustable for comfort. </li></ul></ul><ul><ul><li>The backrest must be firm against your back. </li></ul></ul><ul><ul><li>Your feet should be flat on the floor. </li></ul></ul>
  5. 5. Monitor <ul><li>The screen should: </li></ul><ul><ul><li>Have easily adjustable brightness and contrast controls. </li></ul></ul><ul><ul><li>Be easy to tilt or swivel. </li></ul></ul><ul><ul><li>Have no reflective glare </li></ul></ul><ul><ul><li>Make sure that you sit far enough away from the monitor you are using; most people's natural distance for comfortable vision is 20-24 inches. </li></ul></ul>
  6. 6. Lighting <ul><li>Lighting should: </li></ul><ul><ul><li>Be appropriate for all editing tasks, e.g. reading the screen, keyboard work, paperwork, and must not cause glare or reflections on the monitor. </li></ul></ul><ul><ul><li>Be positioned to reduce glare and reflections. </li></ul></ul><ul><ul><li>Lighting is covered by the Lighting at Work Regulations (1987), which state fluorescent lights which flicker should be replaced to prevent headaches and disturbed vision. </li></ul></ul>
  7. 7. Keyboard <ul><li>The keyboard should: </li></ul><ul><ul><li>have a matte surface to avoid reflective glare. </li></ul></ul><ul><ul><li>Be separate from the monitor and easily tiltable, with clearly marked keys. </li></ul></ul><ul><ul><li>Be easy to use - for example, keys should not stick - and the desk should be large enough to allow adequate space in front of it to position the hands properly. </li></ul></ul>
  8. 8. Environment <ul><li>Computers generate heat, but this must be controlled to a &quot;comfortable&quot; level, if necessary by the use of fans and/or air conditioning. </li></ul><ul><li>The air must not be too dry or too damp. </li></ul><ul><li>Background noise must not be so high that you find it difficult to concentrate. </li></ul><ul><li>In general you should have enough space to be able to change position and vary your movements. </li></ul><ul><li>Take regular breaks from the computer, ideally five minutes every half an hour. This relieves eye strain as well as helping to prevent RSI. </li></ul>
  9. 9. Electrical Appliances <ul><li>The rules for all electrical appliances apply in a computer room. </li></ul><ul><ul><li>There should be no trailing wires. </li></ul></ul><ul><ul><li>Food and drink should not be placed near a machine. </li></ul></ul><ul><ul><li>Electrical sockets must not be overloaded. </li></ul></ul><ul><ul><li>All electrical equipment must be tested for safety at regular intervals. </li></ul></ul>
