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
