Narrative
During flare outage, contractor was grinding on pipe when, due to a valve stem emission leak, sparks flew and ignited a small candle-like flame on the valve stem leak. The candle-like fire was immediately extinguished. The valve was de-pressured and fire blankets were used to prevent this from recurring. Block valves were isolated, piping upstream of the valve stem leak was flared to zero psig and a slip blind was installed to double block the associated segment. The answer to part a question 9 is shown as 0.1 barrels because this is the lowest value the system would allow; the product loss was, actually, so minimal it was not measurable. 1-10-2020 updated following further investigation. The response to part e, question 1 is 300 psig; however, this is only an estimate. The exact pressure is unknown. Also updated response to part e, question 5e.
