Estimation of heat strain in PPE using human thermophysiological model
Original language description
Personal protective equipment (PPE) against CBRN agents is designed to provide perfect barrier between the human body and harmful environment. However, working in PPE accounts for increased risk of heat stress development which may cause heat exhaustion and lead to harmful health consequences. In our research we pursued relationship between thermal insulation of protective ensembles and the induced heat stress. We measured thermal resistance and evaporative resistance using 34-zone Newton thermal manikin on four types of protective ensembles (light impermeable, heavy impermeable, filtration NBC suit and firefighter ensemble). The same types of protective ensembles were examined for inducing heat stress with a group of volunteers performing physical activity in climatic chamber under various ambient conditions. The results from heat stress tests were compared to simulation calculations by means of two thermophysiological models considering ambient temperature, PPE characteristics, individual characteristics of the user and expected energetic demands of the work. As a result, Fiala-based Human Thermophysiological Model which gave more realistic values, was used for development of Predictor of Thermal Strain – an user-friendly computer tool based on extensive database of simulated calculations for estimation of allowable work time limit in PPE under various conditions.
