NFIRS 5.0 Element: ‘Released From’

Definition : The physical location from which the hazardous material was released.
Purpose : Aggregate information on the physical location of hazardous material releases may reveal trends or patterns for particular materials, classes of materials, and physical states. These trends may provide direction for code enforcement or prevention efforts, policymakers, and training curricula.
Entry : If the location of the release was below grade, check or mark the Below Grade box. If the release was inside or on a structure, check or mark the Inside/On Structure box and enter the Story of Release directly below. If the release was outside a structure, check or mark the Outside of Structure box.
For purposes of HazMat data collection, Below Grade also refers to underground releases.
Checking or marking the Below Grade box has the effect of entering a negative number in NFIRS 5.0.
