Narrative
On april 16, 2015 ' operations personnel and contract crew had blown down launching barrel on lid 914b-100 in order to load a cleaning pig. In order to purge the launching barrel with nitrogen of hazardous vapors and not to over pressure the barrel, a pressure relief valve set at 1000 psi was installed on the launching barrel. After the launching barrel was blown down and cleaning pig inserted, the maintenance crew started to re-pressure the launching barrel with product off of the line that was flowing and operating at around 1100 psi. When the pressure on the launching barrel exceeded 1000 psi, the relief valve started relieving to the atmosphere. The valve used to pressure the launching barrel was closed and the relief valve closed off. The 1000 psig relief valve should have been replaced by one set at 1440 psig. The accident and procedures was reviewed with all personnel involved.
