How do oily rags self combust?

Spontaneous combustion of oily rags occurs when rag or cloth is slowly heated to its ignition point through oxidation. A substance will begin to release heat as it oxidizes. If this heat has no way to escape, like in a pile, the temperature will rise to a level high enough to ignite the oil and ignite the rag or cloth.

Why should oily rags and paper never be stored in open containers?

Oil-soaked rags are a spontaneous combustion hazard because as the oil oxidizes, heat is released. If the heat is not dissipated, it can build up and ignite the rags. Special oily-waste cans should be used to store oil-soaked rags. These containers allow air to flow around the rags, thus dissipating the heat.
