Ergonomic Guidelines for Manual Material Handling Department of Health and Human Services

Publisher Marketing: Manual material handling (MMH) work contributes to a large percentage of the over half a million cases of musculoskeletal disorders reported annually in the United States. Musculoskeletal disorders often involve strains and sprains to the lower back, shoulders, and upper limbs. They can result in protracted pain, disability, medical treatment, and financial stress for those afflicted with them, and employers often find themselves paying the bill, either directly or through workers' compensation insurance, at the same time they must cope with the loss of the full capacity of their workers. Scientific evidence shows that effective ergonomic interventions can lower the physical demands of MMH work tasks, thereby lowering the incidence and severity of the musculoskeletal injuries they can cause. Their potential for reducing injury-related costs alone makes ergonomic interventions a useful tool for improving a company's productivity, product quality, and overall business competitiveness. But very often productivity gets an additional and solid shot in the arm when managers and workers take a fresh look at how best to use energy, equipment, and exertion to get the job done in the most efficient, effective, and effortless way possible. Planning that applies these principles can result in big wins for all concerned. This booklet will help you to recognize high-risk MMH work tasks and choose effective options for reducing their physical demands. Illustrated inside you will find approaches like: Eliminating lifting from the floor and using simple transport devices like carts or dollies; Using lift-assist devices like scissors lift tables or load levelers; Using more sophisticated equipment like powered stackers, hoists, cranes, or vacuum assist devices; Guiding your choice of equipment by analyzing and redesigning work stations and workflow.
