Název v původním jazyce

Applicability of Human Thermophysiological Model for Prediction of Thermal Strain in PPE

Popis výsledku v původním jazyce

Use of personal protective equipment (PPE) is an essential way how to protect the human body in hazardous environment with the risk of CBRN agents. On the other hand, the PPE poses a bar-rier to evaporative heat dissipation, therefore, increasing the heat accumulation in the body. In our research we investigated the applicability of the thermophysiological models for prediction of thermal strain and permissible working time in contaminated environment when the usage of protective ensembles is required. We pursued a relationship between the thermal-insulation characteristics of four types of PPE against CBRN agents and the induced thermal strain in set of real physiologic strain tests with human probands wearing PPE in a climatic chamber. Based on the results, we compared predictions using two thermophysiological models – Predicted Heat Strain Index (PHS) and Fiala-based model of thermal comfort (FMTK) with the experimental da-ta. To provide user-friendly platform for estimation of thermal stress in PPE, we developed a us-er-friendly computational tool Predictor of the Thermal Stress (PTS). The PTS tool was validated by means of the results from real tests in climatic chamber. The PTS showed to be easy-to-use computational tool, that can be run on a regular PC, based on real data applicable for the estimation of the permissible work time limit with regard to thermal strain in PPE under various conditions.
