1 How to Achieve an Ergonomic Computer Workstation 58 th Annual Governors Industrial Safety & Health Conference October 7-8, 2009

2 2 Presenters Jeannette Murphy, OTR/L, CEA –Ergonomist, Injury Prevention Specialist –St. Lukes Rehabilitation, Spokane WA Leslie Pickett, PT –Ergonomics and Injury Prevention Specialist –Swedish Medical Center, Seattle WA Lynn LaSalle, MOT –Ergonomist, Ergonomic Coordinator –MultiCare Health System (MHS), Tacoma WA

3 3 Participants will… Understand the ANSI/HFES human factors standards for creating an ergonomic computer workstation. Understand some of the challenges and solutions for using computers in the hospital setting Understand some of the challenges and solutions facing mobile laptop users.

4 4 ANSI/HFES : Human Factors Engineering of Computer Workstations Purpose –To specify acceptable applications of human factors engineering principles and practices to the design and configuration of the human-hardware interfaces in computer workstations.

5 5 ANSI/HFES Application –For computer workstations used regularly in office workplaces by users with normal perceptual and cognitive capabilities –Moderate to intensive computer users –Not intended for beyond the office workplace application –Generalizations to other applications exceed the scope of this standard.

6 6 ANSI/HFES Scope –Applies to computer workstations for a wide range of users –In general the physical dimensions and force requirements are designed to accommodate at least 90 percent of the North American population User Diversity –Design is not intended to accommodate all users due to the very nature of diversity

7 7 ANSI/HFES Guiding Principles –Enhance workstation usability by improving ease of use and ease of learning –Facilitate user performance by encouraging task proficiency and error recovery –Accommodate users of various physical sizes and expertise levels –Maintain user performance by allowing postural changes that minimize static loads –Promote user satisfaction by fostering product acceptance and product usage

8 8 ANSI/HFES Limitations –Not intended for transient computer work situations (e.g., using a laptop computer during airplane travel) or to workstations specially configured for individuals with physical or cognitive disabilities –Use of a portable device in an office setting, such as a laptop computer in a docking station, is not an example of transient computer work. –This standard does not apply to operator health considerations or work practices Focus is to support operator performance through attention to the design aspects of the computer hardware and environment interfaces. No implications are made that conformance to this standard produces health-related outcomes.

9 9 This standard recognized that VDT users frequently change their working postures to maintain comfort and productivity. Four reference postures are used in this standard to represent a range of postures observed at computer workstations.
