PHYSICAL DEMANDS

Physical Demands data elements provide a systematic way of describing the physical activities that an occupation requires of a worker. The assessment of these elements is focused primarily on the physical demands of the job - not the physical capacities of the worker. Physical Demand refers to the level and/or duration of physical exertion generally required to perform occupational tasks (sitting, standing, walking, lifting, carrying, reaching, pushing, and pulling).

This document offers a general overview and basic descriptions of the Physical Demands elements that are collected by the Bureau of Labor Statistics (BLS) for the Occupational Requirements Survey (ORS). These definitions are intended to provide information only and are not intended to be used during the course of data collection.

Physical demands covered:

 

Alternate Sit/Stand or Walk at Will

The ability to alternate between sitting and standing is present when a worker has the flexibility to choose between sitting or standing as needed when this need cannot be accommodated by scheduled breaks and/or lunch period.

Climbing Ramps/Stairs

Ascending or descending ramps and/or stairs using feet and legs. Hands and arms may be used for balance (e.g., to hold a railing).

Note: Stairs involved in commute/getting into building are excluded if work is always performed in one building. Stairs onto a vehicle or a piece of machinery/equipment are included.
