This compound, a green, finely divided material, is bagged and marketed under several trade names. Description of Occupations Exact duplication of occupations is not generally found in the various plants. This is due primarily to variations in the processes, plant layouts, and quantity of production. A given workman’s functions may consist of only a part of the group functions listed or may consist of several group functions. The former is more likely to occur in large plants and the latter in smaller plants. Figure 3 shows the relationship of the eight major functional groups common to the industry according to a simplified flow diagram. Table 1 also shows these eight major groups in the general order of processing, but with their corresponding common occupations and functions. Description of Comparison Plants Three groups of workmen were selected for the purpose of comparison with the workmen in the chromate industry. The working environment for these men was studied for comparison with that of the chromate industry.
