GUIDE TO GOOD PRACTICES FOR
INVESTIGATION OF ABNORMAL EVENTS
This Guide to Good Practices is written to enhance understanding of, and provide direction
for, "Notifications," Chapter VII, and "Investigation of Abnormal Events," Chapter VI, of
Department of Energy (DOE) Order 5480.19, Conduct of Operations Requirements for
DOE Facilities. The practices in this guide should be considered when planning or reviewing
programs for notifications and investigation of abnormal events. Contractors are advised to
adopt procedures that meet the intent of DOE Order 5480.19.
"Notifications" and "Investigation of Abnormal Events" are elements of an effective Conduct
of Operations program. The complexity and array of activities performed in DOE facilities
dictate the necessity for a coordinated notifications program and a consistent method for
investigating abnormal events to promote safe and efficient operations.
