Accident Classified As:

Cause of Problem: Other

Lost power to controls for crude column overhead fans and Uninterruptable Power Supply backup ran out of batteries. Fans shut down leading to necessity of shutdown of the unit and flaring

Discharge Preventable - Yes

Notes/Remedial Actions

The process unit was stablized until an electrician could resote control power to the fans. Once power was restored the equipment was restarted and the unit safely returned to normal conditions. The incident will be investigated and any appropriate corrective actions will be implemented to prevent reoccurrence. Report said it was preventable but did not say why or how. The cover letter/narrative (referencing the verbal notification) mentioned that naphtha and smoke were released, but these were not mentioned elsewhere in the report
