Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: Human Factors

During propylene truck offloading activities, truck rack personnel began the normal Unit 65 process by opening a line to the flare to begin the transfer process. The line should be closed after the transfer to storage begins. However, the Unit 65 personnel failed to close the flare line and an amount of material went to the flare instead of to storage.

Discharge Preventable - Yes

Notes/Remedial Actions

Upon discovery, the line that was open to the flare was closed and the procedure was reviewed with the operator to prevent reoccurrence.
