Preventing tripping hazards

To minimise the risk of tripping, only use the cords that you need for that session and do
not place them across walking areas. Consider the use of extension cords when making
PowerPoint presentations.

Ongoing discomfort or pain

If you are experiencing ongoing discomfort or pain that is not eliminated by the strategies
suggested in this document, seek medical advice and discuss the problem with your
Principal.
Further advice on reducing muscular strain is also available from Employee Support
Services in Central Office on 9264 4889.

Ergonomic and posture principles for general computer use

§ Sit up and back in your chair.
§ The top of the monitor screen should be at or just below
eye level.
§ The monitor should be positioned directly in front.
§ At the correct height for keyboarding your elbows are
approximately level with the keyboard and bent at 90-100
degrees.
§ The knees should be at 90 degrees or greater. A footstool
may be required.
§ Keep elbows close to your sides.
§ Working documents should be between you and the monitor or just to the side of the
monitor on a document holder.
§ Frequently used equipment should be within easy reaching distance.
§ Keep the mouse as close to the keypad as possible and on the same level.
§ Look away from the screen and focus on distant objects regularly to reduce eye
strain (remember that blinking helps to lubricate your eyes).
§ Avoid glare or reflection from windows or lights where possible.
§ Avoid holding your muscles tensed for long periods of time. Stretch and change
postures frequently.
§ Change tasks frequently to help prevent muscle stiffness.
§ Take short frequent micro-breaks. Short and frequent breaks are more beneficial
than longer less frequent breaks. Suggested breaks are 2-3 minutes every 15-20
minutes, 5 minutes every 30 minutes, or 10 minutes every hour.
