Abstract: In order to prevent and eliminate the potential ignition sources in fire and explosive atmosphere, the identification and research ignition properties of ignition sources were studied. Some relative standards and literatures on ignition sources were analyzed, and from the view of prevention and control ignition sources and fire and explosion investigation, the ignition sources were divided into the 7 large term with 26 categories, including hot sources, electrical ignition, mechanically generated sparks, chemical ignition, waves ignition, pyrotechnic materials and others. The characteristic index system of ignition properties for ignition sources was presented, including temperature, energy, flame shape, time frequency and ignition capability. Some quantitative characterization parameters of ignition sources were proposed. The energy distribution of ignition sources,the temperature rangesand some factors influencing the ignition probability were described. The research results showed that the characteristic index system of ignition properties can reflect the correlation between ignition source and fuel, and this is helpful to identify the effective ignition source of fire and explosion atmospheres and reduce the probability of accidents.PC software and mobile APP with security expert knowledge base were developed for online consultation and data sharing.
