2 Ergonomics for Best Performance Presented by: Business Center North NSHE

3 A Definition Ergonomics is the study of how the human body interacts and interfaces with it’s mechanical environment

4 The Ergonomically Correct Seated Position

5 Crude but Effective

6 Standard Ergonomic Equipment ADJUSTABLE CHAIR KEYBOARD TRAY MOUSING DEVICE ADJUSTABLE MONITOR STAND/RISER FOOT REST DOCUMENT HOLDER

7 Chairs One chair will not fit all Try a “variety” of chairs If possible, test a chair for several days Learn how to adjust the chair properly Purchasing requires “service after sale” If it is broken, replace or repair it… NOW!

8 Chairs Chairs are designed to fit a “normative” range of people People who are heavier or lighter, taller or shorter or with disabilities or orthopedic injuries may need a specially ordered chair Chairs designed for continuous use are commercially available

9 The Chair Minimum Adjustments: Height Back Lumbar Support Angle Seat Depth of seat Pan angle (optional) Armrests Height Span Swivel top arms preferred

10 Chair Examples

11 The Keyboard Tray Fully adjustable Grip and Lock Mechanism for those who move tray frequently Wide enough for keyboard and mouse to be placed next to each other Mouse at same height as keyboard There are different models for corner use and straight edge use Pay attention to depth of the track

12 Sample Keyboard and Mouse Trays

13 Keyboard & Mouse Not everyone needs a “natural” keyboard Some do need a “natural” keyboard Literally hundred of keyboards Mouse or trackball is an individual preference Trackball must NOT be thumb operated A wrist rest should be provided for most users Foam vs. Gel is an individual choice Avoid wrist rests that are too thick

14 Sample Keyboards

15

16 Sample Pointing Devices

17 Monitor Monitor Position should allow for normal head and neck position For most, top of monitor screen is at eye level Bifocal wearers like a lower monitor position. Challenge of proper corrective lens Use a monitor riser to gain height Even a phone book or ream of paper will do

18 Sample Monitor Risers

19 Footrests Footrests must be used in the event that proper working height cannot be reached without lifting the chair to height that does not allow the users feet to touch the floor. It is also acceptable as an alternative position for those who sit for extended periods

20 Document Holders Prefer document holder in line with monitor Document holder mounted to side of monitor is acceptable Document holders should hold documents in line and should not bounce or wobble during use.

21 Sample Document Holders

22 Laptop Users Should be provided with docking stations (port replicators), monitor, full size keyboard and mouse for use at a desk. OR Folding Stand with full size peripherals

23 Phones and other office equipment Headsets recommended for individuals who use the phone extensively or who must use both hands while using the telephone Avoid the use of cradles Workers who staple, date stamp and hole punch extensively should be provided with electric models

24 Other thoughts and considerations Fit the workstation to the employee, not vice-versa Everyone is unique Vary Work Tasks Do not ignore complaints of discomfort Be aware of risk factors Avoid awkward/fixed postures Avoid contact stress with hard/sharp surface Address any physical problems early

25 The Economics of Ergonomics Think of the bigger picture Which is cheaper? The average ergonomic claim? $4456.77 High = $54,137.74 Low = $6.10 The average ergonomic office setup? Chair = $500.00 Keyboard Tray = $250.00 Monitor Stand = $100.00 Footrest $50.00 Total $900.00
