Screens
All new screens should be fitted with tilt and swivel stands. Sufficient room is needed for the screen to be moved back and forward. The top of the screen should at eye level. You screen you not be too bright but also not to dull. Because if the screen was to bright are you were looking at it for a long period of time your eyes would get strained and many even damaged.
Making yourself comfortable
As for any task that means working in one position for some time, it's important to make yourself as comfortable as possible when you use your computer. Place the monitor in front of you and at a comfortable viewing distance. If you're working from a document you might find it better to have that directly in front of you and the screen to one side. Try to position the top of the monitor display slightly below eye level when you're sitting at the keyboard.
What you should do before you start
Adjust the positions of the screen, the keyboard, the mouse and the documents you're working from, so as to achieve the most comfortable arrangement. Make sure that you have space to use your mouse easily, and rest your wrists in front of the keyboard when not typing.
Adjust the position of your chair to give you a comfortable viewing distance and posture. The screen should probably be somewhere between eighteen and thirty inches away from you.
Keeping a good posture
To keep a good posture you must sit up straight at all times and you must not slouch over. You must also keep your feet flat on the floor and look straight at the screen. The picture below is the correct posture and you must sit like this at all times.
If you have a problem with your feet touching the ground you should get a foot rest.
Safety is important when working in the I.T industry. If you do not be carful when working n a computer you can get short term are long term injury. These injuries may occur if you spend too much time on the computer e.g. looking at screen to long, back injury, repetitive strain injury etc.
Your work station should be as tidy as possible. This will make it a safe environment to work in as nothing will be in danger of being knocked over e.g. glass of water. If some sort of liquid was knocked over it could fall on electrical equipment and this could cause a fire to occur.
