Standing Work Surfaces
Workstation height is very important. Consideration of anthropometrics together with task
will determine the preferred height. Table 33-10 lists recommended standing work surface
heights for three types of tasks. For lifting tasks, the surface height is somewhat reduced,
and when someone must press downward or generate downward forces, lower heights are
preferred to make it easier to generate the force and keep the elbow nearly straight. In
general, the forearm should be extended slightly beyond horizontal so that the shoulder
muscles do not have to carry as much weight of the arms. Work surface edges should be
rounded to prevent local forces on the arms, and seated workers at standing height work
stations should have foot rests.
