The article presents the results of studies to substantiate the vulnerability functions of a person in light clothes and without personal protective equipment, exposed to heat flows and (or) air temperatures. As experimental data, the published parameters of thermal effects are taken, leading to lesions of an unprotected person at various exposures. The available methods for assessing human vulnerability to the effects of thermal fields when used give large discrepancies when compared with experimental data, especially at initial and final values of temporary exposures, as well as at low and high values of the damaging factor. So, at low values of heat fluxes, the duration of their impact on the degree of damage to a person has little effect, and, conversely, at high values of the heat flux density, the effect of the duration of exposure increases many times over.
In this regard, the problem of substantiating the functions of thermal (temperature) vulnerability of a person with a wide range of intensities of damaging factors and temporary exposures is relevant.
In this work, the functions of human vulnerability under the influence of heat flows and the temperature of the gaseous medium surrounding a person are obtained, which make it possible to assess the damage to a person without protective equipment with a probability of 0%, 50% and 100%. Checking the results of calculations using the obtained mathematical dependences showed a high degree of convergence with the results of known experimental data.
