Getting Ergonomic
Published December 2000
US-based Anthro, Technology Furniture(R)advises that to reduce musculoskeletal disorders among computer users (almost all of us), a business needs to identify physically stressful working conditions and modify employee tasks. To create an ergonomic workplace, Anthro has outlined six safety factors must be considered:
A Perfect Fit. Most desks and tables are around 29 inches high, which is great for doing paperwork or writing. It's too high, though, for keyboarding (the ideal is 23-27 inches) and too low for a monitor, which should be at eye level. Reaching for a too-high keyboard leads to wrist pain, and dropping the head forward to view a too-low monitor strains neck muscles.
The Tall and Short of it. A perfect fit for one employee may be a dangerous misfit for another. Computers and other hardware that are shared by employees of various heights should be supported on an adjustable-height keyboard and mouse tray. Folks can then easily raise or lower the keyboard into a comfortable position, and choose to sit or stand while inputting information.
Up and Down and All Around. For high-tech equipment on the move, mobile carts must have, at a minimum, firmly fastened castors, which glide smoothly and lock securely. Handles and safety straps make it easier still to careen down corridors, across parking lots, and over elevator thresholds.
Sitting Pretty. Chairs should have a backrest, swivel base, and rolling castors. They should also offer adjustment for the seat, back, and height. (If raising the height lifts feet off the floor, add a footrest.) For perfect posture, employees should be trained to make use of the adjustment points on their chairs and computer furniture.
Shed light on the situation. Cut glare on monitor screens by relying on indirect light, which is kindest to eyes. Turn off harsh overhead lights. Close curtains or blinds. Position monitors so windows are to the side of or behind the screen. Then, use a desk or clamp-on lamp to illuminate small areas.
The Cutting Edge. Make sure that computer furniture shelf edges are smooth and rounded, with no sharp corners. Shake stands vigorously to be sure they're stable enough to hold heavy hardware—especially if in motion.
