Spontaneous combustion


DBI is able to evaluate the risk of self-heating and spontaneous combustion in organic materials such as protein powder, fuel pellets, straw and various forms of dust.

DBI can offer customers the testing of organic materials in powder form with a view to preventing self-heating.

Self-heating and spontaneous combustion of organic materials can result in products being destroyed or, in the worst case scenario, a smouldering fire that is difficult to extinguish.
The temperature around a stockpile in a warehouse or storeroom is a critical factor in determining whether or not a process of self-heating can begin. Therefore, DBI has a method for predicting the critical temperature of the surrounding area.

The critical temperature of the surrounding is also called CAT - the Critical Ambient Temperature. If the temperature of the surrounding area is below this limit for a given stockpile, self-perpetuating heating processes cannot develop.

The critical temperature is determined on the basis of tests, whereby a sample of the organic material is heated up slowly in a testing furnace. At the same time, the temperature of the material is recorded.

From the temperature curves it is possible to determine the critical temperature for a given volume of organic material. Alternatively, it is possible to determine the maximum volume of the material it is prudent to store at a given temperature.

Thus, DBI can help you increase levels of fire safety.
