NFIRS 5.0 Element: ‘Last Unit Cleared Date Time’

Definition : The actual month, day, year, and time of day when the last unit cleared the incident scene. This is not an elapsed time.
Purpose : Combined with the previously recorded times, this element is valuable to fire department management in determining the actual time spent at an incident.
Entry : Enter the month, day, year (mm/dd/yyyy), and time that the last unit cleared the scene. If the date is the same as the Alarm date, check or mark the corresponding box; do not reenter the date. However, if the incident extended (from the Alarm time to the Last Unit Cleared time) through midnight, do not check or mark the box; instead, enter the date.
