Ergonomics is the science of designing and adjusting a workplace environment to fit the user's job demands and physical capabilities. Regular ergo evaluations ensure that the computer workstation is fully compatible with the physical capabilities and limitations of the user. Each user has individual needs that require specific calibrations of the workstation setup. An examination of the user's posture and work habits along with the overall arrangement of the workstation can help reduce the likelihood of injuries and increase workplace efficiency.
Instructions
1. Examine the workstation's chair, monitor, keyboard, mouse and work area. The chair should be adjusted so the user's elbows are at the same height as the computer's keyboard and mouse. The chair should ideally have cushioning to support the shoulders and upper back. The mouse should be close enough to the chair that the user does not have to reach to use it, ideally next to the keyboard. The work area should have sufficient space to allow the user full mobility and comfort.
2. Observe the user's posture when working at the computer. The user should sit upright with thighs parallel to the floor, back and shoulders touching the backrest, elbows to the side and feet flat against the floor or in a stable footrest. The monitor should be a comfortable distance from the user's eyes (24 to 30 inches) with the top of the screen at eye level. The user's head and neck should be upright and in line with her torso.
3. Note the user's desk organization. The phone should be placed to the side of the non-dominant hand. Lamps should be placed to maximize illumination of source materials without causing excessive glare. The desktop should be organized so the most frequently used materials are closest to the user.
4. Interview the user regarding work habits, such as frequency and duration of breaks, keyboard and mouse usage and daily tasks. Verify that the user knows adjust the chair's height and that the workstation's appliances and components are in working order.
5. Take notes on all design flaws and problems at the workstation (chair not adjustable, mouse too far from chair) for future reference.
