Source:

1. General organic compounds, especially organic solvents, are apt to catch fire, their vapor or other combustible gases, solid powders (such as hydrogen, carbon monoxide, benzene, oil vapours, flour) when mixed with air by a certain percentage, when there is a spark (spark ignition, EDM, impact) can cause a violent explosion or burning.

2. caused by some chemical reaction exothermic combustion, such as sodium, potassium and other water burn or even explode.

3. some articles are prone to spontaneous combustion (such as white phosphorus on exposure to air to burn on their own), burns due to poor storage and use.

4. some chemicals mixed together, cause burning and explosion under certain conditions (for example red phosphorus and potassium chlorate mixed with, phosphorus will burn them off).
