Environmental Health & Safety

Review of Office Equipment


Careful consideration is needed when selecting and equipping a workstation. This list contains equipment that is familiar to and often recommended by Environmental Health and Safety in response to risk factors. It is important to remember that the recommendations are determined based on the individual, the workstation, and the tasks involved. This information is not comprehensive, and additional factors may influence the effectiveness of this equipment. Approximate costs are listed; university contracts are considered when applicable.

Adjustable Height Worksurface
Adjustable height worksurfaces allow the height of the worksurface to be optimized. High-end versions, which can be adjusted via hand crank or electric motor, allow the operator to easily modify the worksurface height or alternate between having a sitting or standing workstation. They are preferable when multiple employees share the same workstation at different times. Est. Cost: More than $500
Adjustable Keyboard Trays
Adjustable keyboard trays allow the user to optimize the placement of the mouse and keyboard. They are generally recommended for touch typists who type for more than four hours per day. Careful consideration is important when selecting an adjustable keyboard tray. The workstation must meet requirements to accommodate the unit and provide the necessary clearance. The adjustable keyboard tray itself should have a low profile, feature a negative tilt ability, as well support both the keyboard and mouse. Adjustable keyboard trays can be expensive. Cheaper products that are sold in retail stores are usually problematic and should be avoided. Consultation with Environmental Health and Safety or a listed vendor is highly recommended before the purchase of an adjustable keyboard tray. Est. Cost: ~$200
Adjustable Monitor Arms
Adjustable monitor arms greatly increase the flexibility of the workstation by freeing up desk space and allowing the operator to easily move and position their display. In combination with an adjustable keyboard tray, an operator can have enough room to process paperwork and use the video display terminal on a surface as narrow as 24". Est. Cost: ~$200
Cable Extensions
Cable extensions can be used to improve the placement of equipment at a workstation, thus helping to avoid awkward postures. They are also sometimes necessary following changes to a workstation, such as installation of an adjustable keyboard tray or monitor arm. Est. Cost: Less Than $30
Computer Peripherals
Different computer peripherals may be effective in reducing strain. Because product selection is volatile, a list of recommended peripherals is not maintained here. Straight keyboards, split contoured keyboards, flat keyboards that mimic a split keyboard design, and special mouses may all improve posture of the wrists and hands. Other individuals may require equipment that is more specialized. Est. Cost: Usually Less Than $100
Copyholders
Copyholders help maintain neutral positioning when transcribing information from documents to a computer. They can be placed inline with, or mounted to the side of a display. Est. Cost: Less than $50
Corner Sleeves
Corner sleeves are useful for operators who are using an L-shaped desk as a corner workstation. They are installed on the inside corner of the desk, allowing the operator to work against a flat surface. They do rest on the worksurface, creating an edge that can interfere with writing or mouse use. If the L-shaped worksurface consists of systems furniture, the department should consider obtaining a suitable diagonal corner surface instead. Est. Cost: Less than $50
Desk Risers
Desk risers are a simple solution to raise an operator's worksurface. Depending on the workstation, they may or may not be a practical solution. They are designed to hold both feet and edges and are constructed as stackable units, allowing the worksurface to be raised incrementally. Est. Cost: Minimal
Footrests
Footrests provide a comfortable surface for an operator to rest their feet. If the height of the chair prevents an operator from comfortably reaching the floor, a footrest is usually recommended. Est. Cost: Less than $25
Freestanding Furniture
Free standing, static furniture may not seem impressive, though there is a lot available in surplus. If an operator's workstation is deficient, it is very likely that a suitable replacement can be found in surplus. For further information, Contact the PSU Warehouse at 5-4921. Est. Cost: Free through PSU Surplus

Full Spectrum Lighting
Light from fluorescent lamps has a different spectrum than sunlight. This causes fluorescent light to render colors differently which can impact comfort and reduce productivity. Refer to the AOA articles on computer vision syndrome (CVS) for more information. Full spectrum fluorescent lighting is designed to better resemble sunlight, making it more pleasant to many people. Est. Cost: ~$8 per fluorescent tube

Laptop Risers
Laptops are problematic because the display is attached to the keyboard, causing the operator to work with the keyboard, display, or both in an awkward position and impacting their posture. When using a laptop at a workstation, the operator should either use a docking station connected to a keyboard and monitor, or a laptop riser with a separate keyboard in a fashion that is consistent with ergonomic principles. This is necessary for an operator to maintain a healthy posture while working on a notebook computer. Refer to Cornell University's 5 Tips for Using a Laptop Computer for further information. Est. Cost: less than $25
Monitor Risers
In many cases, placing the computer monitor on the worksurface results in the display being too low for the operator to use comfortably. Monitor risers can be used to raise the display to a comfortable height, allowing the head and neck to remain in neutral position. Est. Cost: Less than $25
Palm rests
Palm rests provide a comfortable surface to rest hands on between periods of typing. Ideally, it is better for an operator to type while floating their hands over the keyboard, as opposed to typing while resting their palms on a surface. It is also important to consider the difference between resting palms and resting wrists. Resting wrists should be avoided because this can increase pressure on soft tissues in the wrists and lead to discomfort. Est. Cost: Less than $25
Systems Furniture
Systems furniture is often advantageous because it is highly versatile. It consists of different sizes of panels, worksurfaces, and an array of accessories including but not limited to task lighting, file pedestals, drawers, shelves, and cabinets. The systems are modular and can be reconfigured to meet the needs of an individual.

Departments can procure and install systems furniture through an outside vendor, or they can request assistance from Facilities and Planning.
For assistance with a single workstation, Contact FAP Maintenance at 5-4925. For projects involving multiple workstations, Contact FAP AECS. Est. Cost: Varies widely
Seating Options
For people who spend a significant amount of time sitting at their workstation, it is important that they have a chair that fits their needs. This means that the chair must have dimensions that accommodate the parameters of the individual, support them in a healthy posture, and include features that allow the them to avoid fatigue and slouching. Visit our guide on chair selection. Est. Cost: $250-$800
Task Lighting
Task lighting can be used to increase the illuminance of a specific area. It is handy for tasks such as processing paperwork when lighting in the surrounding space cannot be increased or done so without resulting in adverse effects. Est. Cost: Less than $50
Telephone Headsets and Handset Lifters
For operators who frequently answer the telephone or who use the telephone for long durations should consider obtaining a wireless headset. This helps the operator avoid awkward postures by allowing them the full use of their hands while on the telephone. A handset lifter can be used in combination with a wireless headset to further avoid repetitive motion. A wireless headset system can be obtained through PSU Telecommunications and Networking. Est. Cost: ~$300
Wedge Cushions
Wedge cushions may help an individual maintain a declined posture in a chair without the forward-tilt ability. This may also be useful for individuals who are frequently in meetings away from their office. Est. Cost: Less than $40
