A typical cause of grease fires is leaving a frying pan on the heat unattended. This is pretty obvious, but the type of fuel needs to be considered. [2] A fire naturally occurs when the elements are present and combined in the right mixture. The embers are still extremely hot at this stage though and will likely ignite any fresh fuel that you put on.

Sources of fire are not strong enough for the fire to occur. Water cannot be used on certain type of fires: Since these reactions are well understood, it has been possible to create specific water-additives which will allow: Water-additives are generally designed to be effective on several categories of fires (class A + class B or even class A + class B + class F), meaning a better global performance and usability of a single extinguisher on many different types of fires (or fires that involve several different classes of materials).
