computer workstations
The computer workstation is now a ubiquitous part of an American working day. OSHA has provided workstation ergonomic eTool to ensure that workers using these stations can do so safely and effectively.
The eTool addresses a variety of safety related items, ranging from good working positions to specific risks related to individual components of the workstation. For example, OSHA offers the following tips:
Monitors
Put monitor directly in front of you and at least 20 inches away.
Place monitor so top line of screen is at or below eye level.
Place monitor perpendicular to window.
Keyboards
Put the keyboard directly in front of you.
Your shoulders should be relaxed and your elbows close to your body.
Your wrists should be straight and in-line with your forearms.
Mouse
Keep the pointer/mouse close to the keyboard.
Alternate hands with which you operate the pointer/mouse.
Use keyboard short cuts to reduce extended use.
Desks
Desk surface should allow you to place the monitor directly in front of you, at least 20 inches away.
Avoid storing items, such as a CPU, under desks.
Desks should be able to accommodate a variety of working postures.
Chairs
The backrest should conform to the natural curvature of your spine, and provide adequate lumbar support.
The seat should be comfortable and allow your feet to rest flat on the floor or footrest.
Armrests, if provided, should be soft, allow your shoulders to relax and your elbows to stay close to your body.
The chair should have a five-leg base with casters that allow easy movement along the floor.
Telephones
Use a speaker phone or head set for long conversations.
Keep it close enough to avoid repeated reaching.
