NFIRS 5.0 Element: ‘Exposure Number’
When a fire involves more than one building, each building fire should be considered a separate fire, with the ignition for all but the original building fire classified as exposure fires.
The Incident Date for each exposure remains the same as that of the basic incident; however, the Alarm Time in Block E1 should reflect the time of each new exposure.
|Element Type||Numeric – Integer numbers (no decimal points). If the user has not provided information, an empty field should be transmitted. All integer values are assumed to be positive.
