Back to Ergonomics - Contributing Conditions
Some conditions that may contribute to employees developing MSDs
may be identified through review of injury records, job and work analysis, and
employee input, and may be obvious and not require further analysis. However,
more complex problems may require further analysis before an effective solution
can be designed and implemented.
There are a number of assessment tools available that may assist in analyzing jobs. The following are a
sampling of non-OSHA, off-site analysis tools you may choose to use. The listing of these tools should not be
interpreted, however, as an agency finding in support or rejection of any particular tool.
Manual For the Revised NIOSH Lifting Equation. US Department of Health
and Human Services (DHHS), National Institute of Occupational Safety and
Health (NIOSH) Publication No. 94-110, (1994, January 1). Contains a
complete description of all terms in the lifting equation with several sample calculations.
Evaluation Tools. Washington State Department of Labor and Industries. Links for evaluation tools in PDF and
- Lessons for Lifting and Moving Materials [447 KB PDF, 26 pages].
(2000, February). Provides pertinent information for safety professionals and manufacturing
supervisors on back anatomy, back injuries and methods to avoid the risks
of back injury. A checklist, Lifting Hazard Assessment Worksheet, based on the 1991 NIOSH Revised Lifting Equation,
completed with a score of 6
or higher means the lift is unsafe.
- WAC 296-62-051, Ergonomics (Repealed by ballot initiative 12/4/03) [695 KB PDF, 18 pages].
Washington Administrative Code (WAC), Washington State Labor Department and Industries,
(2000). Includes WISHA Checklist for Work-Related Musculoskeletal Disorders.
The initiative heightened awareness of ergonomics and generated a broader
discussion of this important safety issue. Both sides of the debate have
said that use of proper ergonomic techniques belongs in the workplace and
benefits employers as well as workers.
Manual Materials Handling. Liberty Mutual Research Institute for
Safety. These tables were formerly called the Snook tables.
Analysis Tools for Ergonomists. University of Southern Florida, College
of Public Health, (2007, April 1). Provides tools organized into four
categories: Basic, Qualitative, Semi-Quantitative and Quantitative.
