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.
期刊介绍:
Doklady Physics is a journal that publishes new research in physics of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
