The invention provides a system for assessing a burn and death risk of a human body in a fire environment. A fire scene construction module is used for providing a fire heat radiation environment required by a skin-clothing-environment heat and mass transfer model; the skin-clothing-environment heat and mass transfer model is used for outputting skin temperature distribution of personnel during dressing under exposure of fire heat radiation; a skin temperature data output module is used for outputting skin temperature distribution data output by the skin-clothing-environment heat and mass transfer model; a skin burn prediction module predicts a skin burn degree of the human body according to the skin temperature distribution data and makes a calculation to obtain a burn area ratio of the whole body; and a death risk assessment module assesses a death probability of the personnel exposed to the fire heat radiation environment. According to the system, the demand of predicting the safety condition and death risk of the personnel in the fire heat radiation environment is met and a certain reference meaning is provided for accident rescue and personnel protection.
Description
technical field [0001] The invention belongs to a human body safety assessment system in a fire environment, in particular to a human body burn death risk assessment system in a fire environment. Background technique [0002] In a fire environment, trapped people and rescuers are exposed to high radiation and flames and other hazards, often causing skin burns and other hazards. In the case of high-temperature heat radiation, the heat will pass through the protective clothing from the environment and be transferred to the skin surface, and the skin temperature will increase and there will be a risk of burns. When the human body is continuously exposed to external thermal radiation, the local skin temperature rises to a certain level, causing damage and injury, skin burns occur, and in severe cases, it leads to the risk of death. [0003] Skin burns generally occur when the skin temperature is higher than 44°C. Burns are destructive damages to human skin, and generally human...
