Abstract—
In this paper, we propose to use thermal-protective respirators based on granular phase change materials to protect the respiratory organs from dangerously high temperatures of inhaled air during fires and other emergencies. We demonstrate the possibility of creating such personal protective equipment based on known materials using a numerical experiment. In this case, the insignificant mass of the cooling element based on granular phase change material makes it possible to combine it with a gas and smoke protective element and create combined respirators that protect against both high temperatures and toxic combustion products.
