Narrative
During tank repairs, contract employee removed couplings from the cone roof on the tank with a cutting torch. While in the process of removing a coupling, a hot piece of slag dropped from the cone roof and into the 24"/30" tank sump pipe opening. The hot slag caused a fire in the sump which was quickly extinguished by a contractor. Repairs were shut down and permits pulled. No injuries or equipment was damage as a result of the incident. After the tank was confirmed to have 0% lel, entry was made into the tank to check the tank lateral/sump line. It was discovered that residual product was present in the piping. Residual product was removed from sump piping. Initial nrc #:1211092 and 48 hour nrc#:1211151. Additional hazard reassessment should have been completed before tank repair activities started to prevent occurrence.
