Spontaneous combustion
Spontaneous combustion can occur when a substance with a relatively low ignition temperature such as hay, straw, peat, etc., begins to release heat. This may occur in several ways, either by oxidation in the presence of moisture and air, or bacterial fermentation, which generates heat. These materials are thermal insulators that prevent the
Stop The Fire: How To Prevent Spontaneous Combustion
Spontaneous combustion is a process in which a material self-ignites due to a chemical reaction within itself. This reaction generates enough heat to reach the material''s ignition temperature, causing it to catch fire. Unlike typical fires that require an external heat source, spontaneous combustion occurs spontaneously, hence the name.
