Incident Typing: Overview (Continued)
The incident type corresponds to both the number of resources required and the anticipated incident duration. The incident types move from Type 5 being the least complex to Type 1 being the most complex. As the number of resources required gets larger and the duration of the incident gets longer, the complexity increases. The vast majority of incidents are in the Type 3-5 range.
An image showing an inverted pyramid with different levels of incidents going from Type 1 (at top) to Type 5 (at bottom). The image depicts clocks with longer durations and more people as it moves from Type 5 to Type 1.  There is a bracket which indicates the vast mojority of  all incidents are Types 3, 4, or 5.
Clocks do not depict length of incident time.
