Learn MoreMarch 12, 2021. Auto ignition fires can occur when materials undergo a chemical reaction in the environment in which the materials are stored. Auto ignition is also known as self-ignition or spontaneous combustion. In order for auto ignition to occur, the materials must be able to self-heat to the point that a thermal runaway condition occurs.
