218893 Estimated national burden of physical ergonomic hazards among US workersSunday, November 7, 2010
To estimate the national burden of physical ergonomic hazards among working adults in US, we used proportions of workers who are exposed to physical ergonomic hazards by occupational title obtained from the Occupational Information Network (O*NET) data. These proportions were extrapolated to the Occupational Employment Statistics (OES) from the U.S. Bureau of Labor Statistics (BLS). O*NET contained a total of 28,084 workers in 750 occupations which were used in the analysis. Repetitive motion was the most prevalent of all ergonomic hazards (27%, representing 35 million workers, are estimated to be exposed continually). Non-neutral trunk postures (bending or twisting) were also common, representing over 17 million workers who are estimated to be exposed continually (13% of the US workforce). Kneeling, crouching, stooping or crawling was another ergonomic hazard that 5.7 million US workers perform continuously (4.4% of the US workforce). Almost 2 million workers climb ladders, scaffolds, poles, etc. continually or almost continually at work. We estimate that over 13 million workers (10% of the US workforce) were exposed to cramped work space that requires getting into awkward positions every day. About 3.5 million workers (2.7% of US workforce) were estimated to be exposed to whole body vibration every day. A large portion of the US workforce is exposed to ergonomic hazards known to be associated with musculoskeletal disorders. National efforts are necessary to reduce the burden of ergonomic hazards among US workers.
