  • Just like using any piece of equipment, when using computers you have to think about your health and safety. This is why it is significant to make sure your computer is set–up correctly.
  • The monitor or screen is at the accurate height, the top line in line with your line of eyesight.
    The chair is at the correct height so your feet are on the floor and feel better to work.
  • The screen is at the correct position and brightness to suit the room you are in.
    The
    keyboard and mouse are within easy reach to use them easily.
  • Cables are organized so they don’t clutter up the desk, or get in the way of your legs under the desk.
    Take regular screen breaks so you are not in the similar position for long periods of time.
