There are two types of “combustion explosions”, . deflagrations and detonations. There are other types of “explosions”, . “physical explosions” of vessels by overpressure above the established limit due to overfill, as a result of runaway reaction, etc. The word “explosion” is rather a jargon and we will avoid applying it in this book where possible. Sometimes the use of term “explosion” could generate misunderstanding. For example, some standards do introduce wrongly from author’s point of view so-called “explosion limit”. This is done in spite of the fact that there can be a significant different between the “flammability limit”, which is relevant for deflagrations, and “detonability.
