Essential Physical Requirements

Light: Work involves moving objects by exerting up to 20 pounds of force occasionally, or up to 10 pounds of force frequently, or a negligible amount of force constantly. Physical demand requirements are in excess of those for sedentary work. Even though the weight lifted may be only a negligible amount, a job/occupation is rated for light work when it requires (1) a significant degree of walking or standing, (2) mostly sitting while pushing or pulling arm or leg controls, or (3) working when the weight of the materials is negligible. (The constant stress and strain of maintaining a production-rate pace, especially in an industrial setting, is physically demanding of a worker even though the amount of force exerted is negligible).
