NFIRS 5.0 Element: ‘Cause of Ignition’

Définition : The general causal factor that resulted in a heat source igniting a combustible material. The cause could be the result of a deliberate act, mechanical failure, or act of nature.
 
Purpose : This information is used to determine if further information about the factors related to the fire’s ignition will be collected later in the module. When combined with other data elements that make up the fire’s “ignition chain,” it provides critical information about the nature of the events and the circumstances that caused the fire. This is an important element in understanding the causes of fires.
Entry : Check or mark the box best describing why the heat source and the combustible material were able to combine to initiate the fire. If this is an exposure report, check or mark the top box in this block and skip to Section G.
