Heat stress evaluations in a particular thermal work environment also requires the need of estimating the metabolic
heat generated from a human body. The estimation of this metabolic heat depends on the body surface area (BSA) of the
targeted audience employed in that particular work environment. In this study an attempt was made to evaluate the different
BSA estimates for a group of 51 metal casting workers. Nine different BSA expressions were evaluated based on the
anthropometric variables of casting workers and a comparative analysis among these BSA estimates have been performed. The
results concluded slightly considerable mean variations among the different BSA estimates, although strong association (at
significance level of 0.01) was observed among the different BSA expressions
