Measurement of the thermal insulation (clo) value and evaporative impedance (im/IT) of work clothing systems provides useful information for comparing these systems with regard to heat stress associated with wearing the clothing in hot environments and/or while working at high activity levels. Results of this study indicated that the clothing items which provide the most protection to the wearer from industrial hazards often restrict the amount of body heat loss that is possible through radiation, convection, conduction, and particularly evaporation. Although the copper manikin measurements are useful in ranking work clothing assemblies, they should be supplemented by physiological chamber studies so that human and other environmental factors can be taken into account also. Whether or not a worker will suffer heat stress problems depends upon these factors and their net effect upon the heat exchange between the worker and his/her environment. Ideally, these variables could be manipulated by employers/employees so as to prevent heat stress and at the same time, maintain efficient productivity.
