Beryllium dust can cause fatal and untreatable lung disease, similar to asbestosis.

The symptoms of berylliosis include shortness of breath, cough, chest pain, weight loss and fatigue. These symptoms are common, so that most people who have these symptoms do not have berylliosis. Occasionally, other areas of body like skin, eyes, mouth & nose may develop a rash following contact with dust containing beryllium.

There is no preventive or curative treatment available for berylliosis or chronic beryllium disease.

Windows Help provides extensive help on using keyboard shortcuts with Windows. Individual applications such as Microsoft Office also have their own keyboard shortcuts - with appropriate help. Learning keyboard shortcuts can take some time, but once learnt, using them tends to be faster than using mouse, and avoids much of discomfort associated with mouse. 4. Rest Breaks

All ergonomic experts agree that taking frequent rest breaks is essential to avoid risk of computer related injuries.

You should take frequent "eye breaks" - staring at a computer monitor for long periods causes you to blink less often - resulting in dryer eyes. Every 10 to 15 minutes you should look away from your monitor and blink your eyes rapidly for a few seconds. This will refresh tear film and clear any dust from surface of eyes. Additionally you should focus on something at a distance - preferably 20 feet or more away - look out of window if you can - this will relax muscles inside eye.

You should take frequent short pauses or "micro pauses" - for 10 seconds or so up to a minute - every 10 minutes or thereabouts. You should take regular short breaks - for 5 minutes or more - every hour or so - maybe go for a coffee or a short walk around office, and you should take a long break every two or three hours - for at least 15 minutes, or preferably 30 minutes to an hour. Exactly how long and how frequent your breaks are depends on your own personal preferences and working environment.

5. Stretching Exercises

Regular stretching is an essential part of RSI prevention and recovery, remember that your body is not designed to be sat at a desk for 8 hours a day clicking a mouse. Respect your body and give it movement and range of motion it normally expects.

6. Posture

Good posture is essential to avoid repetitive strain injury and other computer related injuries. Well designed workstation ergonomics can help in maintaining a good posture.

* Make sure that you can reach keyboard with your wrists as flat as possible (not twisted up or down) and straight (not twisted left or right). An ergonomic keyboard can help to keep your wrists straight. * Make sure that your elbow angle is 90 degrees or more to avoid nerve compression at elbow. * Make sure that your upper arm and elbow are as close to body and as relaxed as possible for mouse use - avoid overreaching. Also make sure that your wrist is as straight as possible when mouse is being used. * Make sure that you sit back in chair and that you have good back support - especially lumber support. * Make sure that your feet are flat on floor. Use a foot rest if necessary. * Make sure that your head and neck are as straight as possible . * Make sure that you are relaxed. Forcing yourself to sit up straight can sometimes introduce unhealthy tensions in back muscles.

7. Alternative Input Devices

There are a number of alternative input devices you can use, instead of mouse and keyboard, which you might find helpful. Examples are trackball, a graphics table and pen, a touchpad, and even voice control.

RSI is a very serious health risk, especially with young people who are coming to any industry sector that has continuous use of a PC. You need to take all actions and preventions necessary to help minimize that risk.
