The NFIRS specification provides this definition for Relational Edit Rule 184:
Relational Edit Rule 184 — If Incident Type = 1xx (fire) and either or both of the fields Contents Loss and Property Loss is/are not entered then the system shall generate the following warning message: 'Estimated dollar losses are required for all fires. If there was no loss or no pre-incident value, check or mark the appropriate None boxes. If loss cannot be estimated, do not enter a loss value and no further action is required.'
