Narrative
A tor was discovered in early august with missing outside threads during maintenance work. The decision was made to abandon the tor to prevent future incidents. A new plug was inserted, the cap was installed and stamped as out of service. During the morning of the incident, the maintenance team decided to seal weld the abandoned cap on the damaged tor. During welding, a small amount of product (gasoline) began dripping from under the cap and a small fire ignited. No product reached the ground. The team was able to quickly put out the fire with a fire extinguisher. Update 5/18/2018 the drips stopped after after line was shut down and the pressure was reduced. It was then decided to remove the entire section of piping where the tor was located. Our procedure has been updated in may 2016 to not allow welding on tor fittings with the plug installed. This procedural change was not know by the maintenance group due to not identifying them on the moc for the change on this procedure. The moc distribution list was reviewed and updated. 5/28/2018 per notification from brian pierzina report was not submitted as a final when updated. Submitted as final
