Methods of Forecasting and Evaluating Fire and Explosion Hazards of Mixed Dangerous Substances

To research the danger of the hazardous chemicals' mix and touch, as for the fire and explosion hazards, five forecasting and evaluating methods were summarized and expounded based on the analysis of chemical reaction states and types of mixed dangerous substances. According to the nature of the mixed chemicals, the largest reaction heat, the difference of combustion heat and reaction heat, and freedom enthalpy, a qualitative prediction and evaluation of fire or explosion risk can be theoretically carried out. These methods can be used as a reference for the safety management in the production, storage, transportation, loading and unloading of the dangerous chemicals.
