Overexertion injuries are the leading cause of non-fatal workplace injuries in the US. Overexertion is defined as excessive physical effort. In 1991, Snook and Ciriello published revised maximum acceptable weights for manual material handling activities. These Snook & Ciriello tables include weight limits for males and females, the capabilities of different percentages of the population, and other variables such as varying frequencies, horizontal & vertical hand positions, and travel distances. These weight limits are an essential inclusion in an ergonomics professional's toolbox.

Objectives:

  • Define the purpose of Snook & Ciriello Tables.
  • List which body parts are analyzed by these tables.
  • Identify the Snook & Ciriello Tables input variables.
  • Interpret the Snook & Ciriello scores and their implications.

This presentation will provide a detailed look at AIHA's An Ergonomics Guide to Computer Workstations, 2nd Edition. AIHA defines ergonomics as a multidisciplinary science that applies design principles based on the physical and psychological capabilities of people to the design of jobs, equipment, products, and workplaces. The original 1994 guide summarized the peer-reviewed basic research prior to the early nineties.

Since that time, the knowledge base provided by peer-reviewed data has continued to grow. In addition, the work environment has continued to evolve with significant changes in the equipment used and the time spent on the computer. The 2nd edition updates the information for industrial hygienists and occupational health and safety professionals. The guide provides a means to familiarize individuals designing computer workstations, working with computers for extended periods, and responsible for the health and safety of workers. Focus will be placed on the causes of upper extremity discomfort, back pain, and vision complaints and available controls. We will cover musculoskeletal risk factors such as repetition, forceful exertions, static postures, awkward postures, localized contact stress, psychosocial stress, special applications, and economics.

Objectives:

  • Identify causes of upper extremity discomfort, back pain, and vision complaints.
  • Identify primary musculoskeletal risk factors.
  • Utilize controls for primary musculoskeletal risk factors.
