If these materials are stored in a way so the heat cannot escape, the heat buildup increases the rate of decomposition and thus the rate of heat buildup increases. Linseed oil and Danish oil in a confined space (such as a pile of oil-soaked rags left out in an uncovered container, especially if rags afterward used with anti-moisture solvent to clean up the oil) can oxidize, leading to a buildup of heat and thus ignition. Substances and mixtures with a spontaneous ignition temperature higher than # °C for a volume of # litres should not be assigned to hazard category # of this hazard class MultiUn MultiUn. The presence of water vapor may also be important, as the rate of heat generation accompanying the absorption of water in dry coal from saturated air can be an order of magnitude or more than the same amount of dry air.[10]. This article is cited by Preignition and Autoignition Chemistry of the Xylene Isomers. Some unstable chemical compounds decompose from various causes such as light, mechanical action, biological action, or impurities and in the process they produce heat. spontaneous, ignition, temperature: Etymology spontaneous, ignition, temperature: die Selbstzündungstemperatur. [4][5] Coal can ignite spontaneously when exposed to oxygen, which causes it to react and heat up when there is insufficient ventilation for cooling. As bacteria or fungi cannot survive at temperatures much above 70 to 80°C, continued heating to ignition temperature is due to oxidation, which is chemical in nature.
