Narrative
Based on available information, a contractor employee had removed an existing service tee, and installed a boiler pin into the tap hole. Then it appears that a contract welder began to buff off the pipeline around the boiler pin to prepare for welding the pin into the pipeline. It is assumed that during the buffing operation, the boiler pin released from the pipeline, and it is further assumed that this resulted in a release of gas and this gas then ignited causing burns to the welders face and left elbow. However, the company has not been able to confirm these assumptions with any reasonable amount of certainty.
