Accident Classified As: Reportable Quantity
On October 30, 2012, at 15:20 hours, a propylene rail car was lined up to the flare during unloading process. A Root Cause Analysis is being conducted to determine the exact cause of this incident.
The release was preventable, and results of the Root Cause Analysis will determine recommendations to this type of event in the future. LABB could not locate a follow up notification with these analysis results.
Products Control personnel closed flare line leading from propylene unloading racks to the flare header system. Incident investigation will result in recommendation items designed to prevent recurrence. The reportable quantity for Highly Reactive Volatile Organic Compounds (HRVOCs) was exceeded during the 24 hour period. An incident investigation was conducted to determine the cause or causes of the incident. Per this investigation, the root cause was identified as the procedures were followed incorrectly. The SGS operator misaligned the valve line-up and allowed propylene to offload to the flare. The two recommendations (actions) from the investigation were 1) review and reinforce to personnel the importance of following Operating Guidelines while performing all shift duties- completed 2/18/13; and 2) add proper valve alignment to railcar checklist- completed on 2/20/13.
