[A method of evaluation of work load in an automated chemical plant]

Time-study techniques were used at several chemical enterprises to assess 13 basic elements of the operator's labour, and to determine their average energy inputs in the conditions of a modern chemical plant. A table was drawn up as a time-study guidance for establishing energy inputs in a unit of time, thus determining the labour intensity degree. The contributors set forth a hypothesis regarding the influence of chemical processing products on the non-direct calorimetry indices in energy input analyses. It was further shown that, with the workers contacts with chemical substances in the concentrations peculiar of a modern chemical plant, no correlation corresponding to the chemical factors was required.
