NIOSH: Musculoskeletal disorder prevention takes hands-on approach
Practical Demonstrations of Ergonomic Principles contains a series of demonstrations designed to complement training on ergonomic principles. A description of the materials needed and step-by-step methodology are included.
There were more than 348,000 musculoskeletal disorders, accounting for 28 percent of all workplace injuries and illnesses requiring time away from work in 2009, according to the Bureau of Labor Statistics. The overall rate of MSDs was 33 cases per 10,000 full-time workers, although the rate was 226 for nursing aides, orderlies, and attendants.
MSDs typically involve the back, wrist, elbow, or shoulder, and occur when workers are exposed over time to risk factors, such as awkward postures, forceful exertions, or repetitive motions. These exposures sometimes occur due to poorly designed workstations, tasks, and hand tools.
In addition to understanding the nature of MSD risk factors and how to avoid them, training should involve demonstrations and worker participation, according to NIOSH. That way employees gain a better understanding of the impact that exposures to certain risk factors have on their bodies.
The document includes demonstrations that highlight worker participation and use inexpensive materials. The demonstrations are organized by type of ergonomic principle.
The publication is divided into the following five topics:
1.Neutral compared with non-neutral postures.
3.Hand-tool selection and use.
4.Fatigue failure and back pain.
5.Moment arms (the perpendicular distance between an applied force and the axis of rotation) and lifting.
