Safety and Health Information

To prevent glare on the screen, avoid working with a window or light source behind you.
Turn off lights or close drapes if necessary.
Place your monitor, chair, and work table so that the top of the monitor is slightly below
the top of your head and the screen is 18-28 inches away from you. This may require
placing something under the monitor.
Preventing discomfort and fatigue
Like any activity that involves sitting for long periods of time, using a computer can make
you tired and stiff. In addition, using a keyboard and mouse improperly can sometimes be
associated with RSIs (repetitive stress injuries), particularly in the wrists. Follow these
suggestions to prevent discomfort:
Take frequent breaks. Stand up, stretch, and walk around. These breaks are not wasted
time. They help you work more effectively in the long run.
Adjust your chair so that your lower back and thighs are supported and your feet are ßat
on the ground (or on a footrest).
Adjust your chair and work table so that you can type and use the mouse with your
elbows at a 90¡ angle, your forearms level, and your hands in a straight line with your
forearms. A work table equipped with an adjustable keyboard tray may make this easier.
Do not place your wrists on the hard edge of your table. Use a wrist pad.
Sit up straight in your chair. Slouching puts unnecessary strain on your back.
Do not strike the keys any harder than necessary.
