Definitions for Work Load Classifications in a Return to Work Note

31 October 2012 / California Workers Compensation, How To / Comments Off on Definitions for Work Load Classifications in a Return to Work Note

The definitions below are classifications of work load that are used administratively to communicate the terms of “sedentary”, “light”, “medium” and “heavy” and “very heavy” work.

These terms in and by themselves are not to be used to as standalone work functional instructions, but rather to provide a common reference when reading the literature, or communicating what is accepted as industry standards of the terminology.

Sedentary Work:

Occasional (0%-33% of the Work Day) 10 lbs. Exerting up to 10 lb. of force occasionally and/or a negligible amount of force frequently to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and all other sedentary criteria are met.

 

Light Work:

Occasional (0%-33% of the Work Day) 20 lbs. Frequent (34%-66% of the Work Day) 10 lbs and/or walk/stand, push/pull, or arm/leg controls. Constant (67%-100% of the Work Day) Push/pull or arm/leg controls while seated. Exerting up to 20 lbs of force occasionally, and/or up to 10 lbs of force frequently, and/or a negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for sedentary work.

Even though the weight lifted may be only negligible, a job should be rated light work: (1) when it requires walking or standing to a significant degree, or (2) when it requires sitting most of the time but entails pushing and/or pulling of arm or leg controls; and/or (3) when the job requires working at a production rate pace entailing the constant pushing and/or pulling of materials even though the weight of those materials is negligible.

NOTE: The constant stress and strain of maintaining a production rate pace, especially in an industrial setting, is physically exhausting.

 

Medium Work:

Occasional (0%-33% of the Work Day) 50 lbs. Frequent (34%-66% of the Work Day) 20 lbs. Constant (67%-100% of the Work Day) 10 lbs. Exerting 20-50# of force occasionally, and/or 10 to 25 lbs of force frequently, and/or greater than negligible up to 10 lbs of force constantly to move objects. Physical demand requirements are in excess of those for light work.

 

Heavy Work:

Occasional (0%-33% of the Work Day) 100 lbs. Frequent (34%-66% of the Work Day) 50 lbs. Constant (67%-100% of the Work Day) 20 lbs. Exerting 50 to 100 lbs of force occasionally, and/or 25 to 50 lb of force frequently, and/or 10 to 20 lb of force constantly to move objects. Physical demand requirements are in excess of those for medium work.

 

Very Heavy Work:

Occasional (0%-33% of the Work Day) over 100 lbs. Frequent (34%-66% of the Work Day) over 50 lbs. Constant (67%-100% of the Work Day) over 20 lbs. Exerting in excess of 100 lbs of force occasionally, and/or in excess of 50 lb of force frequently, and/or in excess of 20 lb of force constantly to move objects. Physical demand requirements are in excess of those for heavy work.
