Fast Fires and Hot Fires
A couple terms that you might hear your fire investigator using, but may not understand precisely what they mean to you and your assignment, are “fast fires” and “hot fires”.
Fast Fires–
You may have heard an investigator or a witness referring to a fire as intentionally set because it was a fast fire. Is this a legitimate conclusion to make? It depends. Natural fire progression should be fairly predictable. If fire growth and spread appear to be at odds with expectations, further analysis may reveal they were “helped” along intentionally. Click the video of a demonstration and further explanation.

Hot Fires–
Another term you might hear your fire investigator using, but may not understand precisely is “hot fires.” This term has been used in the past as a justification for a fire cause being classified as incendiary. For example, “We know it was intentionally set because it was a hot fire.”
But is that true? Are incendiary fires especially hot? Is there any validity to the claim that set fires are hot fires? Click below for more information.
