Background technique

Hazardous chemical accidents are different from ordinary accidents. Hazardous chemical accidents are often accompanied by poisoning incidents, which can cause serious secondary injuries and secondary disasters, resulting in a large number of casualties and economic losses. Therefore, after a hazardous chemical accident, no matter the personnel who go to rescue or the medical staff who rescue the patient, they must accurately understand the type, quantity, storage location and physical and chemical characteristics of the hazardous chemical, and choose the appropriate timing and effective protective measures. Only after that can enter the scene for disaster relief or rescue patients, otherwise they will suffer another explosion injury or cause casualties due to poisoning. At present, chemical identification generally adopts microscopic methods such as spectroscopy, chromatography, and mass spectrometry with sophisticated instruments, but such methods are time-consuming and cannot adapt to the unpredictable nature of accident scenes and the urgent need for emergency rescue.
