Tips for Setting Up and Using Your Workstation
The following tips may be useful for setting up an ergonomic work
environment that is safe, comfortable, and productive. Although you may be
able to perform this procedure yourself, it is useful to work with a friend to
achieve the best fit.
Facilities Selection
1. A good work chair should swivel, and you should be able to adjust the
seat height while sitting. The seat should have a rounded front edge.
The chair should have a large enough base to remain stable when
adjusted to its maximum height. It should have castors or glides. Many
chairs rock, which may partially relieve the muscle tension from sitting
in a fixed position. Some chairs can also be adjusted for seat tilt and
depth, armrest height, backrest angle, and lower back support. Check
the chair instructions to take advantage of its adjustability features.
2. Select a work surface that provides enough space to do your work
without excessive turning, twisting, or stretching. The height of the
work surface should be adjustable, and, if possible, the workspace
should be wide enough to use the mouse and keyboard at the same
height. This will help your neck, shoulders, and upper arms to stay
relaxed while you work.
3. Indirect lighting should be used, whenever possible, to prevent glare on
the display screen. If you prefer a lower level of lighting (for example,
200-250 lx) than is usually found in offices, separate task lighting may
be needed for reading documents. Wearing dark-colored clothing helps
minimize glare reflections on the screen.
