A 9-line UXO report is a document with nine blank fields, or sections, for reporting an unexploded ordnance (UXO). UXO is any form of explosive or ammunition that has failed to detonate as intended. The report is used to show where the UXO was sited and what measures were taken.
The nine fields in a UXO report include date-time group discovered, reporting activity and location, contact method, type of explosive, NBC contamination, resources threatened, impact on mission, protective measures taken and recommended priority. An unexploded ordnance includes mortar bombs, shells or sea mines, hand grenades, mines and artillery shells. Reporting an UXO is an important step in protecting the public and also providing a baseline for investigation.
